Changes from 5.0.3 to 5.0.4 (August 2011)
=========================================

The main developers this time were: Trent Gamblin, Matthew Leverton,
Elias Pschernig, Jon Rafkind, Paul Suntsov, Peter Wang and torhu.

Core:

- Restore searching of directories on PATH for DLLs to load on Windows.

- Fix crash on shutdown in headless Unix environment (no X11 display).

- Change all instances of al_malloc + memset(0) to al_calloc.

Graphics:

- Save memory in OpenGL case by freeing bitmap memory after uploading a
texture. Use a temporary buffer when converting lock buffer back to native
texture format.

- Don't release or refresh memory or sub-bitmaps when D3D device gets
lost/found.

- Do not set D3D sub bitmaps to modified when first creating them. This can
cause major slowdowns when creating a lot of sub-bitmaps and is likely
responsible for slow font performance/startup when using D3D.

- Fix incorrect number of display formats in D3D (tobing).

- Honor ALLEGRO_VSYNC in the WGL driver.

- Make titlebar icons the right size on Windows.

- Fix typo causing weird results of al_get_monitor_info on X.

- Don't setup FBO for a sub-bitmap whose parent is locked.

- Specialise ADD/ONE/INVERSE_ALPHA blend mode software scanline drawers.

- Toggle ALLEGRO_VIDEO_BITMAP flag off when creating a memory bitmap (both
bits were previously on).

- Add null bitmap assertion to al_clone_bitmap.

Input:

- New system for mapping extended keys in Windows keyboard driver.
Mainly for getting the same keycode for numpad keys independently of the
state of Num Lock.

- More reliable updating of the toggle modifiers in Windows keyboard driver
(Num Lock, Caps Lock, and Scroll Lock).

Timers:

- Fix race conditions when starting timers from different threads.

Audio addons:

- Don't mix into a global temporary sample buffer, causing noise when two
separate mixers are trying to run in parallel.

- Make it possible to start/stop an audio stream which is attached to a voice.

- ALSA voices could not be resumed after being stopped, because the
update threads quit as soon as a voice is stopped.

- OpenAL backend did not handle the case where _al_voice_update returns less
than a full buffer.

- Attempt to load FLAC and Vorbis DLLs only once to avoid Windows popping up
too many error windows.

Native dialogs addon:

- al_show_native_messagebox() on Windows: add UTF-8 support; show heading;
show information icon by default.

TTF addon:

- Reduce memory usage.

- Don't make multiple passes over strings when computing text dimensions.

Build system:

- Make sure static builds on Windows never use DLL_TLS (Zac Evans).

- Made compilation possible with different combinations of Xinerama,
XF86VidMode, or Randr being present.

- cmake: Use find_path HINTS instead of PATHS in our DirectX SDK scripts.

- cmake: Search for D3DX9 once instead of multiple times (John-Kim Murphy).

- cmake: Find FLAC/Ogg/Vorbis libraries under the names generated by the
official MSVC project files.

- Include zlib.h explicitly for libpng 1.5.

Examples:

- Add multisampling to SPEED example. Change examples to use ALLEGRO_SUGGEST
for multisampling.

- Include the font for speed.app under OSX within the bundle so it can be run
by double clicking.

- Use default blending/pre-multiplied alpha in ex_blend2.

Other:

- Various documentation updates.

- Fix minor memory leaks.

Bindings:

- Better way to make the Python wrapper work with both Python 2 and 3.

- Include Windows-specific functions in the Python wrapper.

Is there a guide to compiling it under windows with mingw?

Edit: I seem to have this problem "D:\Programming\allegro-5.0.4\lib\liballegro-5.0.4-static-mt.a(wsystem.o):wsystem.c|| undefined reference to `PathFindOnPathA@8'|"

You need to link to Shlwapi.lib .

Or, I suppose it's libshlwapi.a on MinGW.^[2]
