0.32 (February 6, 2007)
  - Glyph Keeper now can produce native Allegro FONT objects. This means
     that Glyph Keeper now can be used with AllegroGL.
  - DejaVu Sans 2.14 is now included as example font.
  - Fixed memory leak introduced in 0.30.
  - Added API to debug memory usage in Glyph Keeper and FreeType.
  - Stable centering: Glyph center remains the same when you rotate it.
  - Improved benchmarks.

0.31 (February 2, 2007)
  - Bundled FreeType updated to version 2.3.1.
  - Glyph Keeper now can work with bitmap (raster) fonts.
  - Bytecode interpreter and sublixel rendering are from now OFF by default.
  - gk_rend_set_angle() and gk_rend_set_italic() are deprecated. (They are
     still available if you don't define GK_NO_LEGACY when compiling your
     program). Instead four new functions are introduced:
     gk_rend_set_angle_in_radians(), gk_rend_set_angle_in_degrees(),
     gk_rend_set_italic_angle_in_radians() and
     gk_rend_set_italic_angle_in_degrees().
  - New functions for getting renderer properties:
     gk_rend_get_italic_angle_in_radians(),
     gk_rend_get_italic_angle_in_degrees(), gk_rend_get_bold_strength().
  - New function for creating a copy of a renderer object:
     gk_create_copy_of_renderer().
  - New functions for finding text dimensions: gk_text_dimensions_utf8(),
     gk_text_dimensions_utf16(), gk_text_dimensions_utf32().
  - Dimensions of italic text are now computed correctly.
  - All files use Windows end of line now.
  - Examples are improved.

0.30.1
  - Removed fragments of SDL_gfx code. SDL_gfx is now required to compile
     Glyph Keeper with SDL.
  - Fixed compilation with SDL and MinGW.
  - Fixed angled bold text.
  - Added two functions: gk_rend_set_before_renderer() and
     gk_rend_set_after_renderer() for adding a renderer that will always
     render copy of same character. This can be used for shadows, outlines,
     underlines, etc.

0.30 (January 15, 2007)
  - Fixed compilation with FreeType 2.2.1.
  - Bundled FreeType is updated to version 2.2.1.
  - Applied 64-bit fixes by Hans de Goede.
  - New API: gk_rend_set_bold() for making bold text.
  - Added ability to change font boldness in compare_alleg.c example.
  - license.txt now includes info about bundled 3-rd party software.
  - Removed one C++ style variable declaration in OpenGL driver.
  - Fixed incorrect inclusion of FreeType header in examples/alfont.c,
      reported by gnolam.
  - Added 'delete.me' into the obj dirs, for those with buggy archievers.
  - Fixed "statement with no effect" warning in 'examples/bench_utils.c'.

0.29.1 (July 9, 2005)
  - Added example font (Bitstream Vera) to the examples/ directory.
      Hard-coded this font in text-mode and "Hello, World!" examples and
      set it as default for all other examples.
  - Added 'demofont.pcx' - example font for Allegro benchmark
      (bench_bare_alleg).
  - Minor fixes in Makefiles.

0.29 (July 03, 2005)
  - FreeType is now bundled with Glyph Keeper.
  - Added benchmark examples.
  - Many fixes and improvements in makefiles.

0.28 (June 27, 2005)
  - Added simple examples.
  - Updated documentation.
  - Added install.txt with installation instructions.
  - Added makefile for MinGW.
  - Added makefiles for MSVC 7.1 and 8.0.
  - Changed source indentation: 2 -> 4 spaces. (I did not have a big monitor
      when I started writing GK).

0.27 (June 14, 2005)
  - Hopefully fixed problem occuring in case if FreeType renders
      a 2 or 4-bit glyph (not tested).
  - Now FreeType v.2.1.10 is required to compile Glyph Keeper.
  - From now on you can't mix different versions of Glyph Keeper header and
      library anymore. It will compile and run, just it will never succeed
      to load a font.
  - If you manage to compile Glyph Keeper and your program with different
      targets, it will still not work - it will not load any fonts.
  - Fixed memory leak in _gk_unload_glyph(), reported by biscuitz.
  - From now it is necessary to specify GLYPH_TARGET in the command line
      to compile Glyph Keeper. It will not be set to GLYPH_TARGET_TEXT
      by default, as it was previously.
  - Fladimir da Gorf commented out debug macro and added missing glyph
      deletion in OpenGL driver.
  - New routine: gk_render_char_center().
  - GK_MAX_UNICODE made public again.
  - Fixed gk_render_char() to match documentation.

0.26.2 (May 25, 2005)
  - Added API gk_face_number_of_own_characters_in_range().
  - Fladimir da Gorf updated OpenGL driver to remove the limitation on glyph
      size (or at least making it much greater than it was).

0.26.1 (March 29, 2005)
  - Fladimir da Gorf fixed angled text output with OpenGL target.

0.26 (March 23, 2005)
  - Added OpenGL driver made by Fladimir da Gorf. This is work in progress
      release, OpenGL driver is not finished and has known problems.

0.25 (March 23, 2005)
  - Restructured source to make more easy to see what and where is included.
      (glyph.c now does not have any code, but only includes other files).

0.24 (March 22, 2005)
  - Fixed unclusion of "glyph.h" in glyph.c, pointed by Fladimir da Gorf.
      (Changed to "../include/glyph.h").
  - Added more precaching functions, in hope to use them in OpenGL driver:
      gk_precache_range(), gk_precache_set_utf8(), gk_precache_set_utf16()
      and gk_precache_set_utf32().
  - Fixed bug in gk_precache_char().

0.23.1 (March 9, 2005)
  - Updated documentation.
  - Switched off GLYPH_SAFE and GLYPH_LOG macros, that should be only used
      for debugging. They should be off in released versions because they
      make Glyph Keeper slow. (Forgot to switch them off before the release).

0.23 (March 1, 2005)
  - It should be compatible with upcoming Allegro 4.2, that has
      changed FONT_VTABLE structure since 4.1.18.
  - New function: gk_face_number_of_own_characters().
  - gk_face_number_of_characters() now does not count surrogates.
  - New functions: gk_face_has_character() and gk_face_has_own_character().
  - Added character remapping with API: gk_remap_character(),
      gk_unmap_character(), gk_remap_range(), gk_unmap_range().

0.22 (February 15, 2005)
  - SDL driver is fully functional again.
  - Moved target-specific includes out of extern "C" block, as suggested
      by Oscar Giner.
  - New function: gk_rend_set_color_combined().
  - gk_rend_set_color() is renamed to gk_rend_set_color_rgb(), for clarity.
  - gk_rend_set_size() is renamed to gk_rend_set_size_subpixel(),
      so it will not be used with integer pixel sizes by mistake.
  - Added two macros: gk_makecol(r,g,b) and gk_makeacol(a,r,g,b).

0.21.4 (February 7, 2005)
  - Fixed font path search, finally.
  - Restored text target compilation.
  - Restored C89 compatibility.

0.21.3 (February 7, 2005)
  - Fixed font path search problem, reported by Ken Seergobin.

0.21.2 (February 6, 2005)
  - Added functions for measuring a single glyph / single character.
  - Added gk_set_font_path() function for setting a font search path.
  - Added background rectangle rendering, working for angled text also.
  - Optimized Allegro 32-bit antialiased output with background.
  - Added gk_text_advance_utf8/16/32 functions.
  - Added macros for enabling/disabling RLE and bitpack glyphs compression.
      From now a target driver is not required to handle RLE and bitpacked
      glyphs, linear 8-bit glyph support is enough.
  - UTF-32 decoder now knows about byte order mark.
  - Added GK_NO_LAGACY macro.
  - Minor fixes and changes.

0.21.1 (January 31, 2005)
  - UTF-16 support added.
  - Fixed some brain damage effect in "gk_load_face_from_file()",
      which caused function to fail most of times. (introduced in 0.21)
  - Centering and text width calculation is finally fixed.
  - Added GK_LEGACY macro for controlling compatibility defines.

0.21 (January 31, 2005)
  - All API functions got prefixed with "gk_".
  - Fixed text width calculation bug, reported by Daniel Schlyder.
  - Fixed (hopefully) 64-bit porting problems, following Peter Wang's
      suggestion.
  - Fixed overflow problem with glyph advance values for very
      large font sizes (around 1000 pixels).
  - Fixed Allegro driver's screen access with DJGPP compilation.
  - Fixed C89 compatibility, broken in 0.20.

0.20.1 (January 23, 2005)
  - height field of FONT object now can be used.
  - FONT support works with Allegro 4.1.18.
  - Increased speed of face_get_number_of_characters().

0.20 (January 9, 2005)
  - Added support for creating Allegro FONT objects, as suggested
      by Evert Glebbeek, Serge Semashko, Miran, MattSmith and others.

0.19.1 (December 31, 2004)
  - Bug fixed: When there are two renderers using same font face, one
      italic and other not italic, sometimes non-italic renderer was
      producing italic glyphs. (Reported by Fladimir da Gorf)

0.19 (October 28, 2004)
  - Added italic text rendering, new API: rend_set_italic().
  - Allegro driver was trying to release un-acquired bitmap if text alpha was
      set to 0.

0.18 (October 7, 2004)
  - Changed function of rend_set_size() and rend_set_size_pixels().

0.17 (October 4, 2004)
  - Fix for rend_precache_char().
  - New API function: rend_has_glyph().
  - New API function: load_face_from_memory().
  - New API function: rend_set_error_char().

0.16 (September 30, 2004)
  - Improved drawing speed for Allegro screen bitmap.
  - Antialiased rendering to 8-bit Allegro bitmap does not crash anymore.
  - Removed some obsolete code.

0.15 (September 22, 2004)
  - Some API functions have got better names.
  - Removed text background rendering. It never worked for angled text anyway.
  - Added alpha transparency.
  - Added RLE-like compression for anti-aliased glyphs.
  - Optimized some of the Allegro-specific routines.
  - Added initial SDL support. Only monochrome opaque rendering.
  - Commenting, logging, etc.

Version 0.14 was the first public release (August 22, 2004)
It already had the following:

  - Works with FreeType 2.1.9
  - Rendering directly to Allegro BITMAPS
  - Glyph caching
  - Angled text rendering
  - RLE compression of monochrome glyphs

Before that I did not track the history. If you are curious you can
download Glyph Keeper 0.12 or 0.10 and see what was there.
