* Mon Jun 22 2020 Martin Sirringhaus <>
  - Add patch Fix-big-endian-miscompile-of-bitcast-zex.patch
    to fix miscompilations with rustc 1.43 that lead to LTO failures
* Thu May 14 2020 Martin Sirringhaus <>
  - Update to version 1.43.1
    - Updated openssl-src to 1.1.1g for CVE-2020-1967.
    - Fixed the stabilization of AVX-512 features.
    - Fixed `cargo package --list` not working with unpublished
* Mon May 04 2020 Andreas Schwab <>
  - Update rustfmt_version
* Wed Apr 29 2020 Martin Sirringhaus <>
  - Update to version 1.43.0
    + Language
    - Fixed using binary operations with `&{number}` (e.g. `&1.0`)
      not having the type inferred correctly.
    - Attributes such as `#[cfg()]` can now be used on `if`
    - Syntax only changes:
    * Allow `type Foo: Ord` syntactically.
    * Fuse associated and extern items up to defaultness.
    * Syntactically allow `self` in all `fn` contexts.
    * Merge `fn` syntax + cleanup item parsing.
    * `item` macro fragments can be interpolated into `trait`s,
      `impl`s, and `extern` blocks.
      For example, you may now write:
      macro_rules! mac_trait {
      ($i:item) => {
      trait T { $i }
      mac_trait! {
      fn foo() {}
    * These are still rejected *semantically*, so you will likely
      receive an error but these changes can be seen and parsed by
      macros and conditional compilation.
    + Compiler
    - You can now pass multiple lint flags to rustc to override the
      previous flags.
      For example; `rustc -D unused -A unused-variables` denies
      everything in the `unused` lint group except `unused-variables`
      which is explicitly allowed. However, passing
      `rustc -A unused-variables -D unused` denies everything in
      the `unused` lint group **including** `unused-variables` since
      the allow flag is specified before the deny flag (and therefore
    - rustc will now prefer your system MinGW libraries over its
      bundled libraries if they are available on `windows-gnu`.
    - rustc now buffers errors/warnings printed in JSON.
    + Libraries
    - `Arc<[T; N]>`, `Box<[T; N]>`, and `Rc<[T; N]>`, now implement
      `TryFrom<Arc<[T]>>`,`TryFrom<Box<[T]>>`, and `TryFrom<Rc<[T]>>`
    * *Note** These conversions are only available when `N` is
    - You can now use associated constants on floats and integers
      directly, rather than having to import the module.
      e.g. You can now write `u32::MAX` or `f32::NAN` with no imports.
    - `u8::is_ascii` is now `const`.
    - `String` now implements `AsMut<str>`.
    - Added the `primitive` module to `std` and `core`.
      This module reexports Rust's primitive types. This is mainly
      useful in macros where you want avoid these types being shadowed.
    - Relaxed some of the trait bounds on `HashMap` and `HashSet`.
    - `string::FromUtf8Error` now implements `Clone + Eq`.
    + Stabilized APIs
    - `Once::is_completed`
    - `f32::LOG10_2`
    - `f32::LOG2_10`
    - `f64::LOG10_2`
    - `f64::LOG2_10`
    - `iter::once_with`
    + Cargo
    - You can now set config `[profile]`s in your `.cargo/config`,
      or through your environment.
    - Cargo will now set `CARGO_BIN_EXE_<name>` pointing to a
      binary's executable path when running integration tests or
      `<name>` is the name of your binary as-is e.g. If you wanted
      the executable path for a binary named `my-program`you would
      use `env!("CARGO_BIN_EXE_my-program")`.
    + Misc
    - Certain checks in the `const_err` lint were deemed unrelated
      to const evaluation, and have been moved to the
      `unconditional_panic` and `arithmetic_overflow` lints.
    + Compatibility Notes
    - Having trailing syntax in the `assert!` macro is now a hard
      error. This has been a warning since 1.36.0.
    - Fixed `Self` not having the correctly inferred type. This
      incorrectly led to some instances being accepted, and now
      correctly emits a hard error.
* Tue Apr 07 2020 Andreas Schwab <>
  - Avoid duplication of environment settings
* Tue Mar 31 2020 Antonio Larrosa <>
  - Update to version 1.42.0:
    + Language
    - You can now use the slice pattern syntax with subslices.
    - You can now use #[repr(transparent)] on univariant enums. Meaning
      that you can create an enum that has the exact layout and ABI of
      the type it contains.
    - There are some syntax-only changes:
    * default is syntactically allowed before items in trait
    * Items in impls (i.e. consts, types, and fns) may syntactically
      leave out their bodies in favor of ;.
    * Bounds on associated types in impls are now syntactically
      allowed (e.g. type Foo: Ord;).
    * ... (the C-variadic type) may occur syntactically directly
      as the type of any function parameter.
      These are still rejected semantically, so you will likely receive
      an error but these changes can be seen and parsed by procedural
      macros and conditional compilation.
    + Compiler
    - Added tier 2 support for armv7a-none-eabi.
    - Added tier 2 support for riscv64gc-unknown-linux-gnu.
    - Option::{expect,unwrap} and Result::{expect, expect_err, unwrap,
      unwrap_err} now produce panic messages pointing to the location
      where they were called, rather than core's internals.
      Refer to Rust's platform support page for more information on
      Rust's tiered platform support.
    + Libraries
    - iter::Empty<T> now implements Send and Sync for any T.
    - Pin::{map_unchecked, map_unchecked_mut} no longer require the
      return type to implement Sized.
    - io::Cursor now derives PartialEq and Eq.
    - Layout::new is now const.
    - Added Standard Library support for riscv64gc-unknown-linux-gnu.
    + Stabilized APIs
    - CondVar::wait_while
    - CondVar::wait_timeout_while
    - DebugMap::key
    - DebugMap::value
    - ManuallyDrop::take
    - matches!
    - ptr::slice_from_raw_parts_mut
    - ptr::slice_from_raw_parts
    + Cargo
    - You no longer need to include extern crate proc_macro; to be
      able to use proc_macro; in the 2018 edition.
    + Compatibility Notes
    - Error::description has been deprecated, and its use will now
      produce a warning. It's recommended to use Display/to_string
* Tue Mar 31 2020
  - Rebased patches:
    + ignore-Wstring-conversion.patch (offset / fuzz)
* Mon Mar 23 2020 Federico Mena Quintero <>
  - Update to version 1.41.1:
    - Always check types of static items
    - Always check lifetime bounds of `Copy` impls
    - Fix miscompilation in callers of `Layout::repeat`
  - Update to version 1.41.0:
    + Language
    - You can now pass type parameters to foreign items when implementing
      traits. E.g. You can now write `impl<T> From<Foo> for Vec<T> {}`.
    - You can now arbitrarily nest receiver types in the `self` position. E.g. you can
      now write `fn foo(self: Box<Box<Self>>) {}`. Previously only `Self`, `&Self`,
      `&mut Self`, `Arc<Self>`, `Rc<Self>`, and `Box<Self>` were allowed.
    - You can now use any valid identifier in a `format_args` macro.
      Previously identifiers starting with an underscore were not allowed.
    - Visibility modifiers (e.g. `pub`) are now syntactically allowed on trait items and
      enum variants. These are still rejected semantically, but
      can be seen and parsed by procedural macros and conditional compilation.
    + Compiler
    - Rustc will now warn if you have unused loop `'label`s.
    - Removed support for the `i686-unknown-dragonfly` target.
    - Added tier 3 support\* for the `riscv64gc-unknown-linux-gnu` target.
    - You can now pass an arguments file passing the `@path` syntax
      to rustc. Note that the format differs somewhat from what is
      found in other tooling; please see the documentation for
      more information.
    - You can now provide `--extern` flag without a path, indicating that it is
      available from the search path or specified with an `-L` flag.
      Refer to Rust's [platform support page][forge-platform-support] for more
      information on Rust's tiered platform support.
    + Libraries
    - The `core::panic` module is now stable. It was already stable
      through `std`.
    - `NonZero*` numerics now implement `From<NonZero*>` if it's a smaller integer
      width. E.g. `NonZeroU16` now implements `From<NonZeroU8>`.
    - `MaybeUninit<T>` now implements `fmt::Debug`.
    + Stabilized APIs
    - `Result::map_or`
    - `Result::map_or_else`
    - `std::rc::Weak::weak_count`
    - `std::rc::Weak::strong_count`
    - `std::sync::Weak::weak_count`
    - `std::sync::Weak::strong_count`
    + Cargo
    - Cargo will now document all the private items for binary crates
      by default.
    - `cargo-install` will now reinstall the package if it detects that it is out
      of date.
    - Cargo.lock now uses a more git friendly format that should help to reduce
      merge conflicts.
    - You can now override specific dependencies's build settings. E.g.
      `[] opt-level = 2` sets the `image` crate's
      optimisation level to `2` for debug builds. You can also use
      `[profile.<profile>.build-override]` to override build scripts and
      their dependencies.
    + Misc
    - You can now specify `edition` in documentation code blocks to compile the block
      for that edition. E.g. `edition2018` tells rustdoc that the code sample
      should be compiled the 2018 edition of Rust.
    - You can now provide custom themes to rustdoc with `--theme`, and check the
      current theme with `--check-theme`.
    - You can use `#[cfg(doc)]` to compile an item when building documentation.
    + Compatibility Notes
    - As previously announced 1.41.0 will be the last tier 1 release for 32-bit
      Apple targets. This means that the source code is still
      available to build, but the targets are no longer being tested and release
      binaries for those platforms will no longer be distributed by the Rust project.
      Please refer to the linked blog post for more information.
* Fri Jan 17 2020 Dominique Leuenberger <>
  - Adjust constraints: Request 20GB HDD for all archs. Simplify the
    file by removing the overrides for various disk sizes. All archs
    are curretnly at roughly 17GB storage in use.
* Wed Jan 08 2020 Federico Mena Quintero <>
  - Bump version of libssh2 for SLE15; we now need a version with
    libssh2_userauth_publickey_frommemory(), which appeared in libssh2
  - Use the bundled libssh2 prior to SLE15.  SLE12 has 1.4.3, which is
    too old for the ssh crate now.
* Mon Dec 30 2019 Luke Jones <>
  - Update to version 1.40.0
    + Language
    - You can now use tuple `struct`s and tuple `enum` variant's constructors in
      `const` contexts. e.g.
      pub struct Point(i32, i32);
      const ORIGIN: Point = {
      let constructor = Point;
      constructor(0, 0)
    - You can now mark `struct`s, `enum`s, and `enum` variants with the `#[non_exhaustive]` attribute to
      indicate that there may be variants or fields added in the future.
      For example this requires adding a wild-card branch (`_ => {}`) to any match
      statements on a non-exhaustive `enum`.
    - You can now use function-like procedural macros in `extern` blocks and in
      type positions. e.g. `type Generated = macro!();`
    - Function-like and attribute procedural macros can now emit
      `macro_rules!` items, so you can now have your macros generate macros.
    - The `meta` pattern matcher in `macro_rules!` now correctly matches the modern
      attribute syntax. For example `(#[$m:meta])` now matches `#[attr]`,
      `#[attr{tokens}]`, `#[attr[tokens]]`, and `#[attr(tokens)]`.
    + Compiler
    - Added tier 3 support\* for the
      `thumbv7neon-unknown-linux-musleabihf` target.
    - Added tier 3 support for the
      `aarch64-unknown-none-softfloat` target.
    - Added tier 3 support for the `mips64-unknown-linux-muslabi64`, and
      `mips64el-unknown-linux-muslabi64` targets.
    + Libraries
    - The `is_power_of_two` method on unsigned numeric types is now a `const` function.
    + Stabilized APIs
    - BTreeMap::get_key_value
    - HashMap::get_key_value
    - Option::as_deref_mut
    - Option::as_deref
    - Option::flatten
    - UdpSocket::peer_addr
    - f32::to_be_bytes
    - f32::to_le_bytes
    - f32::to_ne_bytes

    - f32::from_be_bytes
    - f32::from_le_bytes
    - f32::from_ne_bytes
    - f64::from_be_bytes
    - f64::from_le_bytes
    - f64::from_ne_bytes
    - mem::take
    - slice::repeat
    - todo!
    + Cargo
    - Cargo will now always display warnings, rather than only on
      fresh builds.
    - Feature flags (except `--all-features`) passed to a virtual workspace will
      now produce an error. Previously these flags were ignored.
    - You can now publish `dev-dependencies` without including
      a `version`.
    + Misc
    - You can now specify the `#[cfg(doctest)]` attribute to include an item only
      when running documentation tests with `rustdoc`.
    + Compatibility Notes
    - As previously announced, any previous NLL warnings in the 2015 edition are
      now hard errors.
    - The `include!` macro will now warn if it failed to include the
      entire file. The `include!` macro unintentionally only includes the
      first _expression_ in a file, and this can be unintuitive. This will become
      either a hard error in a future release, or the behavior may be fixed to include all expressions as expected.
    - Using `#[inline]` on function prototypes and consts now emits a warning under
      `unused_attribute` lint. Using `#[inline]` anywhere else inside traits
      or `extern` blocks now correctly emits a hard error.
* Mon Dec 30 2019
  - Rebased patches:
    + hopefully-fix-rustdoc-build.patch dropped (merged upstream)
* Fri Nov 29 2019 Neal Gompa <>

  - Update to version 1.39.0
    + Language
    - You can now create async functions and blocks with async fn,
      async move {}, and async {} respectively, and you can now call
      .await on async expressions.
    - You can now use certain attributes on function, closure, and
      function pointer parameters.
    - You can now take shared references to bind-by-move patterns in
      the if guards of match arms.
    + Compiler
    - Added tier 3 support for the i686-unknown-uefi target.
    - Added tier 3 support for the sparc64-unknown-openbsd target.
    - rustc will now trim code snippets in diagnostics to fit in your

      print the output of successful tests.
    + For more details:
  - Drop patches already merged in upstream:
    + rust-61206-assume-tarball-llvm-is-fresh.patch
    + add-option-to-allow-warnings.patch
* Wed Oct 23 2019 Ralf Haferkamp <>
  - Switch to bundled version of libgit2 for now. libgit2-sys seems
    to expect using the bundled variant, which just seems to point
    to a snapshot of the master branch and doesn't match any released
    libgit2 (bsc#1154817).
    See: and for details.
* Mon Sep 30 2019 Luke Jones <>
  - Add patch add-option-to-allow-warnings.patch to add a config option
    which allows warnings and so enables v1.38 to bootstrap itself.
* Mon Sep 30 2019 Luke Jones <>
  - Update to version 1.38.0
    + Language
    - The `#[global_allocator]` attribute can now be used in submodules.
    - The `#[deprecated]` attribute can now be used on macros.
    + Compiler
    - Added pipelined compilation support to `rustc`. This will
      improve compilation times in some cases.
    + Libraries
    - `ascii::EscapeDefault` now implements `Clone` and `Display`.
    - Derive macros for prelude traits (e.g. `Clone`, `Debug`, `Hash`) are now
      available at the same path as the trait. (e.g. The `Clone` derive macro
      is available at `std::clone::Clone`). This also makes all built-in macros
      available in `std`/`core` root. e.g. `std::include_bytes!`.
    - `str::Chars` now implements `Debug`.
    - `slice::{concat, connect, join}` now accepts `&[T]` in addition to `&T`.
    - `*const T` and `*mut T` now implement `marker::Unpin`.
    - `Arc<[T]>` and `Rc<[T]>` now implement `FromIterator<T>`.
    - Added euclidean remainder and division operations (`div_euclid`,
      `rem_euclid`) to all numeric primitives. Additionally `checked`,
      `overflowing`, and `wrapping` versions are available for all
      integer primitives.
    - `thread::AccessError` now implements `Clone`, `Copy`, `Eq`, `Error`, and
    - `iter::{StepBy, Peekable, Take}` now implement `DoubleEndedIterator`.

      multiple features.
    + Misc
    - `rustc` will now warn about some incorrect uses of
      `mem::{uninitialized, zeroed}` that are known to cause undefined behaviour.
* Tue Sep 10 2019
  - Use gcc7 on all of SLE12, since the embedded LLVM wants at least gcc 5.1.
  - Add rust-61206-assume-tarball-llvm-is-fresh.patch - Upstream fix to make
    LLVM not be rebuilt during the installation phase.
* Wed Aug 28 2019 Luke Jones <>
  - Update to version 1.37.0
    + Language
    - #[must_use] will now warn if the type is contained in a tuple,
      Box, or an array and unused.
    - You can now use the `cfg` and `cfg_attr` attributes on
      generic parameters.
    - You can now use enum variants through type alias. e.g. You can
      write the following:
      type MyOption = Option<u8>;
      fn increment_or_zero(x: MyOption) -> u8 {
      match x {
      MyOption::Some(y) => y + 1,
      MyOption::None => 0,
    - You can now use `_` as an identifier for consts. e.g. You can write
      `const _: u32 = 5;`.
    - You can now use `#[repr(align(X)]` on enums.
    - The  `?` Kleene macro operator is now available in the
      2015 edition.
    + Compiler
    - You can now enable Profile-Guided Optimization with the `-C profile-generate`
      and `-C profile-use` flags. For more information on how to use profile
      guided optimization, please refer to the rustc book.
    - The `rust-lldb` wrapper script should now work again.

      default executable to use for `cargo run`.
    - cargo-vendor is now provided as a sub-command of cargo
    + Compatibility Notes
    - Using `...` for inclusive range patterns will now warn by default.
      Please transition your code to using the `..=` syntax for inclusive
      ranges instead.
    - Using a trait object without the `dyn` will now warn by default.
      Please transition your code to use `dyn Trait` for trait objects instead.
* Tue Jul 09 2019 Luke Jones <>
  - Remove fix-llvm8-build.patch, fixed upstream
* Mon Jul 08 2019 Luke Jones <>
  - Update to version 1.36.0
    + Language
    - Non-Lexical Lifetimes are now enabled on the 2015 edition
    - The order of traits in trait objects no longer affects the semantics of that
      object. e.g. `dyn Send + fmt::Debug` is now equivalent to
      `dyn fmt::Debug + Send`, where this was previously not the case.
    + Libraries
    - `HashMap`'s implementation has been replaced with `hashbrown::HashMap` implementation
    - `TryFromSliceError` now implements `From<Infallible>`
    - `mem::needs_drop` is now available as a const fn
    - `alloc::Layout::from_size_align_unchecked` is now available as a const fn
    - `String` now implements `BorrowMut<str>`
    - `io::Cursor` now implements `Default`
    - Both `NonNull::{dangling, cast}` are now const fns
    - The `alloc` crate is now stable. `alloc` allows you to use a subset
      of `std` (e.g. `Vec`, `Box`, `Arc`) in `#![no_std]` environments if the
      environment has access to heap memory allocation.
    - String` now implements `From<&String>`
    - You can now pass multiple arguments to the `dbg!` macro. `dbg!` will
      return a tuple of each argument when there is multiple arguments.
    - `Result::{is_err, is_ok}` are now `#[must_use]` and will produce a warning if
      not used.

      `Box<FnMut>`, and `Box<Fn>` respectively.
    - You can now coerce closures into unsafe function pointers. e.g.
      unsafe fn call_unsafe(func: unsafe fn()) {
      pub fn main() {
      unsafe { call_unsafe(|| {}); }

  - Update to version 1.34.0
    + Language
    - You can now use `#[deprecated = "reason"]` as a shorthand for
      `#[deprecated(note = "reason")]`. This was previously allowed
      by mistake but had no effect.
    - You can now accept token streams in `#[attr()]`,`#[attr[]]`, and
      `#[attr{}]` procedural macros.
    - You can now write `extern crate self as foo;` to import your
      crate's root into the extern prelude.
    + Compiler
    - You can now target `riscv64imac-unknown-none-elf` and
    - You can now enable linker plugin LTO optimisations with
      `-C linker-plugin-lto`. This allows rustc to compile your Rust
      code into LLVM bitcode allowing LLVM to perform LTO optimisations
      across C/C++ FFI boundaries.
    - You can now target `powerpc64-unknown-freebsd`.
    + Libraries
    - The trait bounds have been removed on some of `HashMap<K, V, S>`'s
      and `HashSet<T, S>`'s basic methods. Most notably you no longer
      require the `Hash` trait to create an iterator.
    - The `Ord` trait bounds have been removed on some of
      `BinaryHeap<T>`'s basic methods. Most notably you no longer require
      the `Ord` trait to create an iterator.
    - The methods `overflowing_neg` and `wrapping_neg` are now `const`
      functions for all numeric types.
    - Indexing a `str` is now generic over all types that
      implement `SliceIndex<str>`.
    - `str::trim`, `str::trim_matches`, `str::trim_{start, end}`, and
      `str::trim_{start, end}_matches` are now `#[must_use]` and will
      produce a warning if their returning type is unused.
    - The methods `checked_pow`, `saturating_pow`, `wrapping_pow`, and
      `overflowing_pow` are now available for all numeric types. These are
      equivalvent to methods such as `wrapping_add` for the `pow` operation.

* Sat Mar 02 2019 Luke Jones <>
  - Update to version 1.33.0
    + Language
    - You can now use the `cfg(target_vendor)` attribute. E.g.
      `#[cfg(target_vendor="linux")] fn main() { println!("Hello Linux!"); }`
    - Integer patterns such as in a match expression can now be exhaustive.
      E.g. You can have match statement on a `u8` that covers `0..=255` and
      you would no longer be required to have a `_ => unreachable!()` case.
    - You can now have multiple patterns in `if let` and `while let`
      expressions. You can do this with the same syntax as a `match`
      expression. E.g.
      enum Creature {
      fn main() {
      let state = Creature::Crab("Ferris");
      if let Creature::Crab(name) | Creature::Person(name) = state {
      println!("This creature's name is: {}", name);
    - You can now have irrefutable `if let` and `while let` patterns. Using
      this feature will by default produce a warning as this behaviour can be
      unintuitive. E.g. `if let _ = 5 {}`
    - You can now use `let` bindings, assignments, expression statements,
      and irrefutable pattern destructuring in const functions.
    - You can now call unsafe const functions. E.g.
      const unsafe fn foo() -> i32 { 5 }
      const fn bar() -> i32 {
      unsafe { foo() }
    - You can now specify multiple attributes in a `cfg_attr` attribute.
      E.g. `#[cfg_attr(all(), must_use, optimize)]`
    - You can now specify a specific alignment with the `#[repr(packed)]`
      attribute. E.g. `#[repr(packed(2))] struct Foo(i16, i32);` is a struct
      with an alignment of 2 bytes and a size of 6 bytes.
    - You can now import an item from a module as an `_`. This allows you to
      import a trait's impls, and not have the name in the namespace. E.g.
      use std::io::Read as _;
      // Allowed as there is only one `Read` in the module.
      pub trait Read {}
    - extern` functions will now abort by default when panicking.
      This was previously undefined behaviour.
    + Compiler
    - You can now set a linker flavor for `rustc` with the `-Clinker-flavor`
      command line argument.
    - The mininum required LLVM version has been bumped to 6.0.
    - Added support for the PowerPC64 architecture on FreeBSD.
    - The `x86_64-fortanix-unknown-sgx` target support has been upgraded to
      tier 2 support. Visit the [platform support][platform-support] page for
      information on Rust's platform support.
    - Added support for the `thumbv7neon-linux-androideabi` and
      `thumbv7neon-unknown-linux-gnueabihf` targets.
    - Added support for the `x86_64-unknown-uefi` target.

    - You can now use the `?` operator in macro definitions. The `?`
      operator allows you to specify zero or one repetitions similar to the `*` and
      `+` operators.
    - Module paths with no leading keyword like `super`, `self`, or `crate`, will
      now always resolve to the item (`enum`, `struct`, etc.) available in the
      module if present, before resolving to a external crate or an item the prelude.
      enum Color { Red, Green, Blue }
      use Color::*;
    + All editions
    - You can now match against `PhantomData<T>` types.
    - You can now match against literals in macros with the `literal`
      specifier. This will match against a literal of any type.
      E.g. `1`, `'A'`, `"Hello World"`
    - Self can now be used as a constructor and pattern for unit and tuple structs. E.g.
      struct Point(i32, i32);
      impl Point {
      pub fn new(x: i32, y: i32) -> Self {
      Self(x, y)
      pub fn is_origin(&self) -> bool {
      match self {
      Self(0, 0) => true,
      _ => false,
    - Self can also now be used in type definitions. E.g.
      enum List<T>
      Self: PartialOrd<Self> // can write `Self` instead of `List<T>`
      Cons(T, Box<Self>) // likewise here
    - You can now mark traits with `#[must_use]`. This provides a warning if
      a `impl Trait` or `dyn Trait` is returned and unused in the program.
  - Compiler
    + The default allocator has changed from jemalloc to the default allocator on
      your system. The compiler itself on Linux & macOS will still use
      jemalloc, but programs compiled with it will use the system allocator.
    + Added the `aarch64-pc-windows-msvc` target.
  - Libraries
    + `PathBuf` now implements `FromStr`.
    - `Box<[T]>` now implements `FromIterator<T>`.
    - The `dbg!` macro has been stabilized. This macro enables you to
      easily debug expressions in your rust program. E.g.
      let a = 2;
      let b = dbg!(a * 2) + 1;
      //      ^-- prints: [src/] a * 2 = 4
      assert_eq!(b, 5);

* Thu Dec 06 2018 Luke Jones <>
  - Update to version 1.31.0
    + Language
    - This version marks the release of the 2018 edition of Rust.
    - New lifetime elision rules now allow for eliding lifetimes in functions and
    impl headers. E.g. `impl<'a> Reader for BufReader<'a> {}` can now be
    `impl Reader for BufReader<'_> {}`. Lifetimes are still required to be defined
    in structs.
    - You can now define and use `const` functions. These are currently
    a strict minimal subset of the const fn RFC. Refer to the
    [language reference][const-reference] for what exactly is available.
    - You can now use tool lints, which allow you to scope lints from external
    tools using attributes. E.g. `#[allow(clippy::filter_map)]`.
    - `#[no_mangle]` and `#[export_name]` attributes can now be located anywhere in
    a crate, not just in exported functions.
    - You can now use parentheses in pattern matches.
    + Compiler
    - Updated musl to 1.1.20
    + Libraries
    - You can now convert `num::NonZero*` types to their raw equivalvents using the
    `From` trait. E.g. `u8` now implements `From<NonZeroU8>`.
    - You can now convert a `&Option<T>` into `Option<&T>` and `&mut Option<T>`
    into `Option<&mut T>` using the `From` trait.

  - Jump from version 1.26.2 to 1.30.0 due to a build issue with using 1.26.x to
    compile 1.27.x. This package release requires %{rust_bootstrap} to be set.
  - Enable extra rust tools to be built (cargo, rls, rustfmt, analysis)

    Update to version 1.30.0 (2018-10-25)
    + Language
    - Procedural macros are now available.-  These kinds of macros allow for
      more powerful code generation. There is a new chapter available
      in the Rust Programming Language book that goes further in depth.
    - You can now use keywords as identifiers using the raw identifiers
      syntax (`r#`),-  e.g. `let r#for = true;`
    - Using anonymous parameters in traits is now deprecated with a warning and
      will be a hard error in the 2018 edition.-
    - You can now use `crate` in paths.-  This allows you to refer to the
      crate root in the path, e.g. `use crate::foo;` refers to `foo` in `src/`.
    - Using a external crate no longer requires being prefixed with `::`.-
      Previously, using a external crate in a module without a use statement
      required `let json = ::serde_json::from_str(foo);` but can now be written
      as `let json = serde_json::from_str(foo);`.
    - You can now apply the `#[used]` attribute to static items to prevent the
      compiler from optimising them away, even if they appear to be unused,-
      e.g. `#[used] static FOO: u32 = 1;`
    - You can now import and reexport macros from other crates with the `use`
      syntax.-  Macros exported with `#[macro_export]` are now placed into
      the root module of the crate. If your macro relies on calling other local
      macros, it is recommended to export with the
      `#[macro_export(local_inner_macros)]` attribute so users won't have to import
      those macros.
    - You can now catch visibility keywords (e.g. `pub`, `pub(crate)`) in macros
      using the `vis` specifier.-
    - Non-macro attributes now allow all forms of literals, not just
      strings.-  Previously, you would write `#[attr("true")]`, and you can now
      write `#[attr(true)]`.
    - You can now specify a function to handle a panic in the Rust runtime with the
      `#[panic_handler]` attribute.-
    + Compiler
    - Added the `riscv32imc-unknown-none-elf` target.-
    - Added the `aarch64-unknown-netbsd` target-
    + Libraries
    - `ManuallyDrop` now allows the inner type to be unsized.-

    - `Iterator::find_map`
    - The following methods are replacement methods for `trim_left`, `trim_right`,
      `trim_left_matches`, and `trim_right_matches`, which will be deprecated
      in 1.33.0:
      + `str::trim_end_matches`
      + `str::trim_end`
      + `str::trim_start_matches`
      + `str::trim_start`
    + Cargo
    - `cargo run` doesn't require specifying a package in workspaces.][cargo/5877]
    - `cargo doc` now supports `--message-format=json`.][cargo/5878] This is
      equivalent to calling `rustdoc --error-format=json`.
    - Cargo will now provide a progress bar for builds.][cargo/5995]
    + Misc
    - `rustdoc` allows you to specify what edition to treat your code as with the
      `--edition` option.-
    - `rustdoc` now has the `--color` (specify whether to output color) and
      `--error-format` (specify error format, e.g. `json`) options.-
    - We now distribute a `rust-gdbgui` script that invokes `gdbgui` with Rust
      debug symbols.-
    - Attributes from Rust tools such as `rustfmt` or `clippy` are now
      available,-  e.g. `#[rustfmt::skip]` will skip formatting the next item.
  - Update to version 1.29.2 (2018-10-11)
    + Workaround for an aliasing-related LLVM bug, which caused miscompilation.
    + The `rls-preview` component on the windows-gnu targets has been restored.
  - Update to version 1.29.1 (2018-09-25)
    + Security Notes
    - The standard library's `str::repeat` function contained an out of bounds write
      caused by an integer overflow. This has been fixed by deterministically
      panicking when an overflow happens.
  - Update to version 1.29.0 (2018-09-13)
    + Compiler
    - Bumped minimum LLVM version to 5.0.
    - Added `powerpc64le-unknown-linux-musl` target.
    - Added `aarch64-unknown-hermit` and `x86_64-unknown-hermit` targets.
    + Libraries
    - `Once::call_once` no longer requires `Once` to be `'static`.
    - `BuildHasherDefault` now implements `PartialEq` and `Eq`.
    - `Box<CStr>`, `Box<OsStr>`, and `Box<Path>` now implement `Clone`.
    - Implemented `PartialEq<&str>` for `OsString` and `PartialEq<OsString>`
      for `&str`.
    - `Cell<T>` now allows `T` to be unsized.
    - `SocketAddr` is now stable on Redox.
    + Stabilized APIs
    - `Arc::downcast`
    - `Iterator::flatten`
    - `Rc::downcast`
    + Cargo
    - Cargo can silently fix some bad lockfiles.][cargo/5831] You can use
      `--locked` to disable this behavior.
    - `cargo-install` will now allow you to cross compile an install
      using `--target`.][cargo/5614]
    - Added the `cargo-fix` subcommand to automatically move project code from
      2015 edition to 2018.][cargo/5723]
    - `cargo doc` can now optionally document private types using the
      `--document-private-items` flag.][cargo/5543]
    + Misc
    - `rustdoc` now has the `--cap-lints` option which demotes all lints above
      the specified level to that level. For example `--cap-lints warn`
      will demote `deny` and `forbid` lints to `warn`.
    - `rustc` and `rustdoc` will now have the exit code of `1` if compilation
      fails and `101` if there is a panic.
    - A preview of clippy has been made available through rustup.
      You can install the preview with `rustup component add clippy-preview`.
    + Compatibility Notes
    - `str::{slice_unchecked, slice_unchecked_mut}` are now deprecated.
      Use `str::get_unchecked(begin..end)` instead.
    - `std::env::home_dir` is now deprecated for its unintuitive behavior.
      Consider using the `home_dir` function from instead.
    - `rustc` will no longer silently ignore invalid data in target spec.
    - `cfg` attributes and `--cfg` command line flags are now more
      strictly validated.
  - Update to version 1.28.0
    + Language
    - The `#[repr(transparent)]` attribute is now stable.-  This attribute
      allows a Rust newtype wrapper (`struct NewType<T>(T);`) to be represented as
      the inner type across Foreign Function Interface (FFI) boundaries.
    - The keywords `pure`, `sizeof`, `alignof`, and `offsetof` have been unreserved
      and can now be used as identifiers.-
    - The `GlobalAlloc` trait and `#[global_allocator]` attribute are now
      stable.-  This will allow users to specify a global allocator for
      their program.
    - Unit test functions marked with the `#[test]` attribute can now return
      `Result<(), E: Debug>` in addition to `()`.-
    - The `lifetime` specifier for `macro_rules!` is now stable.-  This
      allows macros to easily target lifetimes.
    + Compiler
    - The `s` and `z` optimisation levels are now stable.-  These optimisations
      prioritise making smaller binary sizes. `z` is the same as `s` with the
      exception that it does not vectorise loops, which typically results in an even
      smaller binary.
    - The short error format is now stable.-  Specified with
      `--error-format=short` this option will provide a more compressed output of
      rust error messages.
    - Added a lint warning when you have duplicated `macro_export`s.-
    - Reduced the number of allocations in the macro parser.-  This can
      improve compile times of macro heavy crates on average by 5%.
    + Libraries
    - Implemented `Default` for `&mut str`.-
    - Implemented `From<bool>` for all integer and unsigned number types.-
    - Implemented `Extend` for `()`.-
    - The `Debug` implementation of `time::Duration` should now be more easily
      human readable.-  Previously a `Duration` of one second would printed as
      `Duration { secs: 1, nanos: 0 }` and will now be printed as `1s`.
    - Implemented `From<&String>` for `Cow<str>`, `From<&Vec<T>>` for `Cow<[T]>`,
      `From<Cow<CStr>>` for `CString`, `From<CString>, From<CStr>, From<&CString>`
      for `Cow<CStr>`, `From<OsString>, From<OsStr>, From<&OsString>` for
      `Cow<OsStr>`, `From<&PathBuf>` for `Cow<Path>`, and `From<Cow<Path>>`
      for `PathBuf`.-
    - Implemented `Shl` and `Shr` for `Wrapping<u128>`
      and `Wrapping<i128>`.-
    - `DirEntry::metadata` now uses `fstatat` instead of `lstat` when
      possible.-  This can provide up to a 40% speed increase.
    - Improved error messages when using `format!`.-

    + Cargo
    - Cargo will now no longer allow you to publish crates with build scripts that
      modify the `src` directory.][cargo/5584] The `src` directory in a crate should be
      considered to be immutable.
    + Misc
    - The `suggestion_applicability` field in `rustc`'s json output is now
      stable.-  This will allow dev tools to check whether a code suggestion
      would apply to them.
    + Compatibility Notes
    - Rust will consider trait objects with duplicated constraints to be the same
      type as without the duplicated constraint.-  For example the below code will
      now fail to compile.
      trait Trait {}
      impl Trait + Send {
      fn test(&self) { println!("one"); } //~ ERROR duplicate definitions with name `test`
      impl Trait + Send + Send {
      fn test(&self) { println!("two"); }
  - Update to version 1.27.2:
    + Compatibility Notes
    - The borrow checker was fixed to avoid an additional potential unsoundness when using
      match ergonomics
  - Update to version 1.27.1:
    + Security Notes
    - rustdoc would execute plugins in the /tmp/rustdoc/plugins directory
      when running, which enabled executing code as some other user on a
      given machine. This release fixes that vulnerability; you can read
      more about this on the blog. The associated CVE is [CVE-2018-1000622].
      Thank you to Red Hat for responsibily disclosing this vulnerability to us.
    + Compatibility Notes
    - The borrow checker was fixed to avoid an additional potential unsoundness when using
      match ergonomics
  - Update to version 1.27.0:
    + Language
    - Removed 'proc' from the reserved keywords list. This allows `proc` to
      be used as an identifier.
    - The dyn syntax is now available. This syntax is equivalent to the
      bare `Trait` syntax, and should make it clearer when being used in tandem with
      `impl Trait` because it is equivalent to the following syntax:
      `&Trait == &dyn Trait`, `&mut Trait == &mut dyn Trait`, and
      `Box<Trait> == Box<dyn Trait>`.
    - Attributes on generic parameters such as types and lifetimes are
      now stable. e.g.
      `fn foo<#[lifetime_attr] 'a, #[type_attr] T: 'a>() {}`
    - The `#[must_use]` attribute can now also be used on functions as well as
      types. It provides a lint that by default warns users when the
      value returned by a function has not been used.
    + Compiler
    - Added the `armvte-unknown-linux-musleabi` target.
    + Libraries
    - SIMD (Single Instruction Multiple Data) on x/x_ is now stable.
      This includes arch::x & arch::x_ modules which contain
      SIMD intrinsics, a new macro called `is_x_feature_detected!`, the
      `#[target_feature(enable="")]` attribute, and adding `target_feature = ""` to
      the `cfg` attribute.
    - A lot of methods for `[u]`, `f`, and `f` previously only available in
      std are now available in core.
    - The generic `Rhs` type parameter on `ops::{Shl, ShlAssign, Shr}` now defaults
      to `Self`.
    - std::str::replace` now has the `#[must_use]` attribute to clarify
      that the operation isn't done in place.
    - Clone::clone`, `Iterator::collect`, and `ToOwned::to_owned` now have
      the `#[must_use]` attribute] to warn about unused potentially
      expensive allocations.

    - `cargo-metadata` now includes `authors`, `categories`, `keywords`,
      `readme`, and `repository` fields.
    - `cargo-metadata` now includes a package's `metadata` table.
    - Added the `--target-dir` optional argument. This allows you to specify
      a different directory than `target` for placing compilation artifacts.
    - Cargo will be adding automatic target inference for binaries, benchmarks,
      examples, and tests in the Rust 2018 edition. If your project specifies
      specific targets, e.g. using `[[bin]]`, and have other binaries in locations
      where cargo would infer a binary, Cargo will produce a warning. You can
      disable this feature ahead of time by setting any of the following to false:
      `autobins`, `autobenches`, `autoexamples`, `autotests`.
    - Cargo will now cache compiler information. This can be disabled by
      setting `CARGO_CACHE_RUSTC_INFO=0` in your environment.
    + Compatibility Notes
    - Calling a `CharExt` or `StrExt` method directly on core will no longer
      work. e.g. `::core::prelude::v1::StrExt::is_empty("")` will not
      compile, `"".is_empty()` will still compile.
    - `Debug` output on `atomic::{AtomicBool, AtomicIsize, AtomicPtr, AtomicUsize}`
      will only print the inner type. E.g.
      `print!("{:?}", AtomicBool::new(true))` will print `true`,
      not `AtomicBool(true)`.
    - The maximum number for `repr(align(N))` is now 2²⁹. Previously you
      could enter higher numbers but they were not supported by LLVM. Up to 512MB
      alignment should cover all use cases.
    - The `.description()` method on the `std::error::Error` trait
      has been soft-deprecated. It is no longer required to implement it.
    + Misc
    - Added “The Rustc book” into the official documentation.
* Thu Oct 11 2018
  - Add CVE-2018-1000622-prevent-rustdoc-loads-uncontrolled-plugins-path.patch:
    + This patch consists of requiring `--plugin-path` to be passed
      whenever `--plugin` is passed
    + rustdoc plugins will be removed entirely on 1.28.0, we should
      drop this patch after 1.28.0(bsc#1100691, CVE-2018-1000622).

    - `fn main() -> impl Trait` no longer works for non-Termination trait
      This reverts an accidental stabilization
    - `NaN > NaN` no longer returns true in const-fn contexts
    - Prohibit using turbofish for `impl Trait` in method arguments
* Sat May 12 2018
  - Update to version 1.26.0:
    + Language:
    - Closures now implement `Copy` and/or `Clone` if all captured
      variables implement either or both traits.
    - The inclusive range syntax is now stable.
    - Stablise `'_`. The underscore lifetime can be used anywhere
      where a lifetime can be elided.
    - `impl Trait` is now stable allowing you to have abstract
      types in returns or in function parameters.
    - Pattern matching will now automatically apply dereferences.
    - 128-bit integers in the form of `u128` and `i128` are now
    - `main` can now return `Result<(), E: Debug>` in addition to
    - A lot of operations are now available in a const context.
    - Fixed entry slice patterns are now stable. e.g.
    + Compiler:
    - LLD is now used as the default linker for `wasm32-unknown-\
    - Fixed exponential projection complexity on nested types.
      This can provide up to a ~12% reduction in compile times for
      certain crates.
    - Added the `--remap-path-prefix` option to rustc. Allowing you
      to remap path prefixes outputted by the compiler.
    + Libraries:
    - Implemented `From<u16> for usize & From<{u8, i16}> for
    - Added hexadecimal formatting for integers with fmt::Debug.
    - Implemented `Default, Hash` for `cmp::Reverse`.
    - Optimized `str::repeat` being 8x faster in large cases.
    - `ascii::escape_default` is now available in libcore.
    - Trailing commas are now supported in std and core macros.
    - Implemented `Copy, Clone` for `cmp::Reverse`.
    - Implemented `Clone` for `char::{ToLowercase, ToUppercase}`.

    - Deprecate `AsciiExt` trait in favor of inherent methods.
    - `".e0"` will now no longer parse as `0.0` and will instead
      cause an error.

    + `str::find::<char>` now uses memchr. This should lead to a 10x
      improvement in performance in the majority of cases.
    + `time::{SystemTime, Instant}` now implement `Hash`.

      instead abort.
    + `Formatter::flags` method is now deprecated. The `sign_plus`,

    + Arbitrary `auto` traits are now permitted in trait objects.[45772]
    + rustc now uses subtyping on the left hand side of binary operations.[45435]
      Which should fix some confusing errors in some operations.
  - Compiler changes:
    + Enabled `TrapUnreachable` in LLVM which should mitigate the impact of
      undefined behaviour.[45920]
    + rustc now suggests renaming import if names clash.[45660]
    + Display errors/warnings correctly when there are zero-width or
      wide characters.[45711]
    + rustc now avoids unnecessary copies of arguments that are

    + rustdoc now prints rendering warnings on every run.[45324]
    + Release tarballs now come with rustfmt[45903]
  - Compatibility Notes:

    + Stabilised the `compile_fail` attribute for code fences in doc-comments.
      This now lets you specify that a given code example will fail to compile.
  - Compatibility Notes
    + The minimum Android version that rustc can build for has been bumped
      to `4.0` from `2.3`

  -Language updates:
      + [Stabilize pub(restricted)][40556] `pub` can now accept amodule path to
      make the item visible to just that module tree. Also accepts the keyword
      `crate` to make something public to the whole crate but not users of the
      library. Example: `pub(crate) mod utils;`. [RFC 1422].
      + [Stabilize `#![windows_subsystem]` attribute][40870] conservative exposure of the
      `/SUBSYSTEM` linker flag on Windows platforms. [RFC 1665].
      + [Refactor of trait object type parsing][40043] Now `ty` in macros can accept
      types like `Write + Send`, trailing `+` are now supported in trait objects,

      + [Now warns if you bind a lifetime parameter to 'static][40734]
      + [Tuples, Enum variant fields, and structs with no `repr` attribute or with

      + [rustdoc now accepts `#` at the start of files][40828]
      + [Fixed jemalloc support for musl][41168]
  - Compatibility Notes:
      + [Changes to how the `0` flag works in format!][40241] Padding zeroes are now
      always placed after the sign if it exists and before the digits. With the `#`
      flag the zeroes are placed after the prefix and before the digits.
      + [Due to the struct field optimisation][40377], using `transmute` on structs
      that have no `repr` attribute or `#[repr(Rust)]` will no longer work. This has
      always been undefined behavior, but is now more likely to break in practice.
      + [The refactor of trait object type parsing][40043] fixed a bug where `+` was
      receiving the wrong priority parsing things like `&for<'a> Tr<'a> + Send` as
      `&(for<'a> Tr<'a> + Send)` instead of `(&for<'a> Tr<'a>) + Send`
      + [Overlapping inherent `impl`s are now a hard error][40728]
      + [`PartialOrd` and `Ord` must agree on the ordering.][41270]
      + [`rustc -o out --emit=asm,llvm-ir`][41085] Now will output
      `out.asm` and `out.ll` instead of only one of the filetypes.
      + [ calling a function that returns `Self` will no longer work][41805] when
      the size of `Self` cannot be statically determined.
      + [rustc now builds with a "pthreads" flavour of MinGW for Windows GNU][40805]
      this has caused a few regressions namely:
      + Changed the link order of local static/dynamic libraries (respecting the
      order on given rather than having the compiler reorder).
      + Changed how MinGW is linked, native code linked to dynamic libraries
      may require manually linking to the gcc support library (for the native
      code itself)
* Wed May 10 2017
  - Adjustment of rust version dependency to prevent inability to

  - Compiler updates
    * [`rustc` now supports `--emit=metadata`, which causes rustc to emit
      a `.rmeta` file containing only crate metadata][38571]. This can be
      used by tools like the Rust Language Service to perform
      metadata-only builds.
    * [Levenshtein based typo suggestions now work in most places, while
      previously they worked only for fields and sometimes for local
      variables][38927]. Together with the overhaul of "no
      resolution"/"unexpected resolution" errors (#[38154]) they result in

  - Language updates
    * Basic procedural macros allowing custom `#[derive]`, aka "macros 1.1", are
    stable. This allows popular code-generating crates like Serde and Diesel to
    work ergonomically. [RFC 1681].
    * [Tuple structs may be empty. Unary and empty tuple structs may be instantiated
    with curly braces][36868]. Part of [RFC 1506].
    * [A number of minor changes to name resolution have been activated][37127].
    They add up to more consistent semantics, allowing for future evolution of
    Rust macros. Specified in [RFC 1560], see its section on ["changes"] for
    details of what is different. The breaking changes here have been transitioned
    through the [`legacy_imports`] lint since 1.14, with no known regressions.
    * [In `macro_rules`, `path` fragments can now be parsed as type parameter
    * [`?Sized` can be used in `where` clauses][37791]
    * [There is now a limit on the size of monomorphized types and it can be
    modified with the `#![type_size_limit]` crate attribute, similarly to
    the `#![recursion_limit]` attribute][37789]
  - Compiler changes
    * [On Windows, the compiler will apply dllimport attributes when linking to
    extern functions][37973]. Additional attributes and flags can control which
    library kind is linked and its name. [RFC 1717].
    * [Rust-ABI symbols are no longer exported from cdylibs][38117]
    * [The `--test` flag works with procedural macro crates][38107]
    * [Fix `extern "aapcs" fn` ABI][37814]
    * [The `-C no-stack-check` flag is deprecated][37636]. It does nothing.
    * [The `format!` expander recognizes incorrect `printf` and shell-style
    formatting directives and suggests the correct format][37613].
    * [Only report one error for all unused imports in an import list][37456]
  - Compiler performance
    * [Avoid unnecessary `mk_ty` calls in `Ty::super_fold_with`][37705]
    * [Avoid more unnecessary `mk_ty` calls in `Ty::super_fold_with`][37979]
    * [Don't clone in `UnificationTable::probe`][37848]
    * [Remove `scope_auxiliary` to cut RSS by 10%][37764]
    * [Use small vectors in type walker][37760]
    * [Macro expansion performance was improved][37701]
    * [Change `HirVec<P<T>>` to `HirVec<T>` in `hir::Expr`][37642]
    * [Replace FNV with a faster hash function][37229]

    packaged versions haven't successfully built in the past
* Fri Dec 23 2016
  - Update to version 1.14.0
      + Announcement:
      + Details:
  - Release highlights:
      + support for RFC 1492. This small addition lets you use `..`
      in more places, for example when destructuring a struct or tuple
      + println!(), with no arguments, prints newline
      + Wrapping impls standard binary and unary operators on
      references, as well as the Sum and Product iterators, making
      references to these types easier to use
      + Implement From<Cow<str>> for String and From<Cow<[T]>> for
      Vec<T>. These implementations make sense, but were not yet added.
      + Expand .zip() specialization to .map() and .cloned() for
      improved performance.
      + Implement RefUnwindSafe for atomic types, as these types are
      “unwind safe,” though that wasn’t obvious at first.
      + Specialize Vec::extend to Vec::extend_from_slice for
      performance gains.
      + Don’t reuse HashMap random seeds. This helps to mitigate one
      type of DDoS attack.
      + The internal memory layout of HashMap is more cache-friendly,
      for significant improvements in some operations
      + Impl Add<{str, Cow<str>}> for Cow<str>. We already support Add
      for other string types, so not having it on Cow is inconsistent.

      the compiler, and so did a number of usability improvements
      across the documentation, rustdoc itself, and various error
      + This is the first release, which is guaranteed to be built
      by previous stable release of rustc

* Mon May 30 2016
  - Update to version 1.9.0
      + Stabilization of std::panic
      + Deprecation warnings, #[deprecated] attribute
      + Compile time improvements

      + Library stabilizations
      About 80 library functions and methods are now stable in 1.
* Fri Apr 15 2016
  - Update to version 1.8.0:
      + Various “operator equals” operators, such as += and -=, are now
      overloadable via various traits.
      + Empty struct declaration can contain cutly braces
      + New (non default) cargo based build system for rustc
      + About 20 library functions and methods are now stable in 1.8
* Fri Mar 04 2016
  - Update to version 1.7.0:
      + Many stabilized APIs
      + Improved library performance
      + BTreeSet and its iterators, Iter, IntoIter, and Range are covariant over their contained type.
      + LinkedList and its iterators, Iter and IntoIter are covariant over their contained type.
      + str::replace now accepts a Pattern, like other string searching methods.
      + Any is implemented for unsized types.
      + Hash is implemented for Duration.
      + Soundness fixes, may break code. See RFC 1214 for more information.
      + Several bugs in the compiler's visibility calculations were fixed.
      + Parsing "." as a float results in an error instead of 0.
      + Borrows of closure parameters may not outlive the closure.
* Wed Jan 20 2016
  - Update to version 1.6.0:
      + Stabilization of libcore and other library functions
      + disallows wildcards
* Fri Oct 30 2015
  - Update to version 1.4.0:
      + Several changes have been made to fix type soundness and improve the
      behavior of associated types. See RFC 1214. Although we have mostly
      introduced these changes as warnings this release, to become errors next
      release, there are still some scenarios that will see immediate breakage.
      + The str::lines and BufRead::lines iterators treat \r\n as line breaks in
      addition to \n.
      + Loans of 'static lifetime extend to the end of a function.
      + str::parse no longer introduces avoidable rounding error when parsing
      floating point numbers. Together with earlier changes to float
      formatting/output, "round trips" like f.to_string().parse() now preserve
      the value of f exactly.  Additionally, leading plus signs are now accepted.
* Sat Oct 17 2015
  - Split the gdb support to rust-gdb subpackage
* Fri Sep 18 2015
  - Update to version 1.3.0:
      + API stabilization, including the new Duration API and
      enhancements to Error and Hash/Hasher.
      + The substring matcher now uses a more efficient algorithm.
      + There were improvements to zero filling that speed up
      Vec::resize and Read::read_to_end.
      + The implementation of Read::read_to_end has been specialized
      for stdin and File, resulting in additional speedups.
      + The PartialEq implementation on slices is now much faster.
  - Packaging: renamed source package to rustc to match upstream
* Wed Aug 12 2015
  - Update to version 1.2.0:
      + An across-the-board improvement to real-world compiler performance.
      Representative crates include hyper (compiles 1.16x faster), html5ever
      (1.62x faster), regex (1.32x faster) and rust-encoding (1.35x faster). You
      can explore some of this performance data at Nick Cameron’s preliminary
      tracking site, using dates 2015-05-15 to 2015-06-25.
      + Parallel codegen is now working, and produces a 33% speedup when
      bootstrapping on a 4 core machine. Parallel codegen is particularly useful
      for debug builds, since it prevents some optimizations; but it can also be
      used with optimizations as an effective -O1 flag. It can be activated
      by passing -C codegen-units=N to rustc, where N is the desired number
      of threads.
* Mon Jul 27 2015
  - Update to version 1.1.0:
    + The std::fs module has been expanded to expand the set of
      functionality exposed:
    * DirEntry now supports optimizations like file_type and
      metadata which don't incur a syscall on some platforms.
    * A symlink_metadata function has been added.
    * The fs::Metadata structure now lowers to its OS counterpart,
      providing access to all underlying information.
    + The compiler now contains extended explanations of many errors.
      When an error with an explanation occurs the compiler suggests
      using the --explain flag to read the explanation. Error
      explanations are also available online.
    + Thanks to multiple improvements to type checking, as well as other
      work, the time to bootstrap the compiler decreased by 32%.
  - drop tar_scm service and use source urls
* Fri May 15 2015
  - Update to version 1.0.0:
