Changes from 5.2.7 to 5.2.8 (June 2022)

The main developers this time were: SiegeLord, Elias Pschernig, Sebastian Krzyszkowiak, Julian Smythe.

Build system:

• Add a configuration summary. Currently this mostly reports the addon features.

• Fix build failure with sanitizers enabled.

• Remove -Wdeclaration-after-statement, MSVC had support for this for a while now.

• Bump minimum CMake version to 3.0.

Core:

• Add al_fopen_slice mode to prevent seek on close (Karl Robillard).

• Allow configuring bitmap wrapping via al_set_new_bitmap_wrap.

Graphics:

• Reject creating bitmaps with negative width or height (Peter Hull).

• Add a minimal shader implementation for GLSL. Minimal shader supports fewer features, but is faster (Issue [#1120]). Select it via the _MINIMAL suffix to the shader platforms.

Emscripten:

• Improve emscripten instructions for building demos (Connor Clark).

• Fix usage of SDL_Init for emscripten (Issue [#1322]) (Connor Clark).

OSX:

• Fix a few thread-related crashes.

• Don't use -flat_namespace in LINK_FLAGS (danielnachun).

• Make al_get/set_window_position work on Retina displays

Windows:

• Fix flickering when creating multisampling displays under DirectX.

• Fix multisampling selection on Windows with OpenGL.

• Fixed a bug which freezes and crashes the window in Windows OpenGL (HerrNamenlos123).

• Allow specifying shader model 3_0 for HLSL shaders (Issue [#1154]).

SDL:

• Ignore touch events from indirect touch devices.

• Use SDL_PeepEvents for event handling, to improve performance.

• Improve joysticks support (Issue [#1326]) (Connor Clark).

• Fix mouse axis setter (Connor Clark).

Linux:

• Use clock_gettime with CLOCK_MONOTONIC instead of gettimeofday (check-switch-26).

Android:

• Update Gradle to 5.0.

Audio addon:

• Add ALLEGRO_PLAYMODE_LOOP_ONCE (Issue [#1309]).

• Add al_play_audio_stream, a 'simple' API endpoint for audio stream playback.

Acodec addon:

• Fix Vorbis/Opus support under MSVC + Clang.

• Add audio identification / al_identify_sample.

• Use regular seeking for Ogg streams. The old one did cross-fades, causing unexpected behavior in certain cases (Issue [#1310]).

• Enable looping for modules.

Audio addon:

• Allow identifying and listing audio devices via new API: al_get_num_audio_output_devices, al_get_audio_output_device, al_get_audio_device_name (Aldrik Ramaekers).

Color addon:

• Add linear and oklab color spaces to the color addon.

Font addon:

• Fix declaration of al_draw_multiline_textf() as a PRINTFUNC (check-switch-26).

Image addon:

• Prevent RLE data in corrupt .tga from overflowing the buffer (Peter Hull).

• PCX loader validation (Peter Hull).

• Windows BMP - Make more robust to crashing (Peter Hull).

• Fix DDS compressed image loading when image dimensions are not multiple of block size (check-switch-26).

Native Dialog addon:

• Fix native dialogs addon compatibility with older GTK+ versions (Andrew Kravchuk).

TTF addon:

• Fixed TTF rendering when using transforms (check-switch-26).

PhysFS addon:

• Fix incorrect error handling in PHYSFS_close (j-w-c-b).

Video addon:

• Allow identifying video files via a magic number, exposed via al_identify_video (Issue [#1262]).

• Fix al_is_video_addon_initalized (Jayson).

Documentation:

• Document some reasonable defaults for al_create_mixer/al_create_voice.

• Refactor the audio docs to highlight the simple API better.

Misc:

• Fix a few data race issues, in an effort to fix ex_threads crashes on Linux.

Examples:

• Allow exiting from ex_audio_timer (BillKek)

• Add the Allegro 4 "shooter" demo.

• Fix ex_threads crash under D3D.

• Add ex_audio_devices.

• Update ex_palette to build with Emscripten (Issue [#1318]).

• Improve ex_stream_seek.

• Improve ex_windows.
