    * New functions added for displaying a pix from a pixa.
    * Split out sort/hash/set/map functions for dna, sarray and pta.
    * More robust horizontal deskew on multi-column page images.
    * Improve webpio_reg test.
    * Remove X11 display for gplot; it is no longer supported.
    * Remove most sleep calls, which were put in for gplot; no longer needed.
    * Removed use of gthumb in library.
    * Removed use of pixDisplayWrite() in the library; still in some progs.
    * Improved test for endianness in makefile.static; no longer requires
      any local files or building and running a program.
    * Modified all files for doxygen output (spearheaded by Jurgen Buchmuller)
    * Improved plotting of the boxes in a boxa.
    * Replaced the slow point hash function with a simple fast one.
    * Added pam (4 component) format writing to pnmio.c (Jurgen Buchmuller)

    * More serialized boot recognizers stored as self-generating code.
    * Cleaned up generating an adapted recognizer from the boot recognizer.
    * Simplified temp file naming; removed most instances of named
      temp files from non-debug code; use tmpfile() and a wrapper
    * Simplify and streamline multipage tiff reading (Jeff Breidenbach).
    * Improvement of Otsu thresholding.
    * Recognize outstanding contributors to leptonica over the years.
    * New gif mem read/write interface that avoids writing a temp file,
      contributed by Tobias Peirick.
    * Use double arrays (dna) instead of float (numa) for set ops.
    * Cleanup of gray quantization functions and tests.

    * Final mods for compatibility with tesseract 4.00.
* Tue Feb 02 2016
  - Update to 1.73.
    * All lept_* functions have been rewritten to avoid path rewrites
      for output to temp files, which were introduced in 1.72.
    * Added grayscale histogram functions that can be used to compare
    * Added functions to determine if an image region has horizontal
      text lines.
    * Added functions to compare photo regions of images to determine
      if they're essentially the same.
    * Added red-black tree utility functions to implement maps and
    * Improved security of tiff and gif reading, to prevent memory
      corruption when reading bad data.
  - Change major library version to 5.
  - Change programs prefix from "leptonica" to "lept" (make the names
    simpler to use).
* Sun Sep 27 2015
  - Update to 1.72:
    * Better handling of 1 bpp colormap read/write with png so that
      they are losseless. The colormap is always removed on read and
      the conversion is to the simplest non-cmapped pix that can
      fully represent the input -- both with and without alpha.
    * Fixed overflow bug in pixCorrelationBinary().
    * Fixed orientation flags and handling of 16 bit RGB in tiff.
    * Also new wrappers to TIFFClientOpen(), so we no longer go
      through the file descriptor for memory operations.
    * Improvements in the dewarp functions.
    * New box sequence smoothings.
    * New antialiased painting through mask; previously it was only
      implemented for connected components in a mask.
    * Better error handling and debug output with jpeg2000
    * Implemented base64 encoding. This allows binary data to be
      represented as a C string that can be compiled. Used this in
      bmf utility.
    * Implemented automatic code generation for deserialization from
      compiled strings (stringcode.*)
    * Regression tests write to leptonica subdir of in windows; in
      unix it is optional.  This avoids spamming the directory.
    * Added new colorspace conversions (XYZ, LAB).
    * New source files: encoding.c, bmfdata.h, stringcode.c,
      stringcode.h, bootnumgen.c.
    * Removed source files: convolvelow.c, graymorphlow.c
    * New programs: genfonts_reg, colorize_reg, texturefill_reg,
      autogentest1, autogentest2.
    * alltests_reg now has 66 tests.
  - Added new build requirement openjpeg2-devel for openSUSE > 13.1.
* Sat Sep 27 2014
  - Update to 1.71.
    * This version supports tesseract 3.0.4. In particular, 3.0.4 has
      automatic conversion of a set of scanned images, either in a
      directory or coming directly from a scanner, into pdf with
      injected text. This is something we've wanted to do for several
    * Improved jp2k header reading, including resolution.
    * Removed src files: rotateorthlow.c, pdfio.c, pdfiostub.c.
    * Renamed jp2kio.c, jp2kiostub.c ==> jp2kheader.c,
      jp2kheaderstub.c. These header reading functions parse the jp2k
      files, and don't require a jpeg2000 library.
    * New jp2kio.c, jp2kiostub.c, that uses openjpeg-2.X to read and
      write jp2k. We now support I/O from these formats: png, tiff,
      jpeg, bmp, pnm, webp, gif and jp2k as well as writing to
      PostScript and pdf.
    * New pdfio1.c, pdfio1stub.c, pdfio2.c pdfio2stub.c, where we've
      split functions into high and low level.
    * Fixed memory bug in bilateral.c.
    * Improved reading/write of binary data from file. For example,
      l_binaryReadStream() can now be used to capture data piped in
      via stdin.
    * Font directory now arg passed in everywhere (not hardcoded).
    * Don't write temporary files to /tmp; only to a small number of
      subdirectories, to avoid spamming the /tmp directory. E.g., for
      regression tests, the current output is now to /tmp/regout/.
    * For jpeg reading modify pixReadJpeg() to take as a hint a bit
      flag that allows extraction of only the luminance channel.
    * Allow wrapping of pdf objects from png images without
    * Better support for alpha on read/write with png, including 1
      bpp with colormap, alpha (supported in png with transparency
* Sun Jan 26 2014
  - Update to 1.70.
    * New bilateral filtering.
    * New simple character recognition utility.
    * Improved dewarping functionality, in model building and
      rendering. More flexible use of ref models.
    * Better and more consistent handling of alpha layer in RGBA,
      though use of the spp field.  Ability to handle more png files
      with alpha, including palette with alpha.
    * New fast converters from jpeg and jpeg2000 to pdf, without
    * Made bmp reader (and pix reading in general) more robust; avoid
      size overflow errors.
    * New text labelling operations; depth conversion of a set of
  - Major version changed to 4.
  - Rename liblept-devel to leptonica-devel.
  - Drop liblept-1.69-no_return and leptonica-1.69-giflib5 patches
    (fixed upstream).
  - BuildRequires: pkgconfig(libwebp) >= 0.2.0
  - Correct URL and a source URL.
* Tue Mar 12 2013
  - fix build with giflib-5.x, leptonica-1.69-giflib5.patch
