• Fix building examples with non-Allegro dependencies with the monolith build.

Documentation:

• Various documentation updates (Daniel Johnson and others).

Other:

• Add more #include statements in Allegro headers, so it’s easier to use them in isolation (Jordan Woehr).

• Allow marking tests as being hardware only.

• Prefix some private Allegro macros and types to not pollute the namespace.

• Make set_shader_uniform api const-correct (Bruce Pascoe).

Audio addon:

• Adjust loop end position when calling al_set_sample_instance_length.

Acodec addon:

• Allow file-backed audio streams to be restarted after they finish.

• Add Opus codec support.

Image addon:

• Fail gracefully if not built with PNG/JPG loaders.

Native dialog addon:

Font addon:

• Make al_get_text_dimensions and al_get_glyph_dimensions return exact bounding boxes (koro).

• Add ALLEGRO_GLYPH structure and al_get_glyph, allowing for some additional optimization when drawing fonts.

Examples:

• Add more controls to ex_audio_props.

• Add an example of using Enet with Allegro.

Changes from 5.1.13.1 to 5.2.0 (April 2016)

The main developers this time were: SiegeLord, Polybios, Mark Oates, Elias Pschernig and Jonathan Seeley.

Core:

• Add al_is_event_source_registered (koro).

• Make destructors log messages more meaningful.

• Mouse emulation API for touch devices is now unstable.

• Rename al_convert_bitmaps to al_convert_memory_bitmaps.

Input:

• Haptic API is now unstable.

Android port:

• Fixed bogus display destruction on Android which previously caused zombie states.

OSX port:

• Fix OSX mouse state position scaling.

• Fix other various scaling issues.

• Make toggling ALLEGRO_FRAMELESS work.

• Fix an issue where fullscreen windows would occasionally leave empty space for the titlebar.

• Fix incorrect debug assert in the audio addon.

Windows port:

• Make Allegro apps DPI-aware by default, which means that they won’t be scaled by the OS.

• Fix compilation for the CPU detection code on some compilers.

• Don’t sync the D3D bitmap when locking with WRITE_ONLY.

• Remove dsound.dll runtime loading.

• Don’t link xinput and d3dx9 libraries (they are still required at runtime though if you’re using the relevant features).

• Fix a bug where al_wait_for_event_timed can block despite 0 timeout (Aldo Nunez).

Build system:

• Install PDB files when building with MSVC.

Documentation:

• Fix source links for API entries with multi-line prototypes.

• Make the readme look prettier on GitHub.

• Tons of assorted documentation improvements, especially for the audio addon.

Other:

• Add a stability system where some unstable APIs need to be opted into by defining ALLEGRO_UNSTABLE before including Allegro headers.

Audio addon:

• Fix sporadic deadlocks

• Recorder API is now unstable.

Native dialog addon:

• al_toggle_menu_item_flags is now unstable.

TTF addon:

• Add an option to pre-cache the glyphs, useful for platforms where the current algorithm is buggy (typically some Android devices).

Video addon:

• Temporarily remove FFmpeg backend, as it was too buggy, didn’t build and was too hard to fix.

Examples:

• Make ex_vsync less likely cause a seizure.

• Make ex_draw_bitmap and ex_touch_input switch in/out on Android.

• Add documentation to ex_bitmap (Daniel Johnson).

• Improve ex_logo text entry experience.
