2009-12-22 - Allegro 4.4.0 released!

This is the first release of the 4.4 branch, which is backwards compatible with the stable 4.2 branch, and the intended successor. The main change is that the following addons are bundled in, so you do not have to hunt them down and install them separately: AllegroGL, loadpng, JPGalleg, logg. We have also switched over to the CMake build system, which we have been using for the unstable 4.9 branch. See the full list of changes.

Unfortunately, Allegro 4.4.0 does not support DOS, BeOS/Haiku or QNX. We welcome interested parties to restore support for any of these platforms. For Haiku/QNX, it should be a simply matter of updating the build system.

2009-10-04 - Allegro 4.2.3 released!

This is an bug fix release for Allegro 4.2. Here is a list of the principal changes since version 4.2.2:

Fix fnstsw compile bug with newer binutils.
Trent Gamblin made a small change to the Windows mouse driver to add support for touchscreens (at least 1 of them).
Peter De Wachter made the ALSA driver work for hardware which does not support unsigned samples.
Matthew Leverton fixed a problem with filename encoding and the SYSTEM_NONE driver. Added set_filename_encoding(), get_filename_encoding().
Milan Mimica made the MinGW and MSVC makefiles add the suffix "_c" onto non-asm builds, and clarified that user programs linking against the non-asm libraries must also defined ALLEGRO_USE_C. Mixing calling conventions causes segfaults when functions are inlined.
AJ added detection for SSSE3, SSE4.1 and SSE4.2
David A. Capello made key_shifts work properly on Windows for Control, Alt, and Shift.
Clarified that set_config_file() does not search for the given config file in other locations, as Allegro does with allegro.cfg at initialization.
Fixed buffer overflow in exgui.
Fixed problems with newer versions of autoconf.
