Changes from 5.2.6 to 5.2.7 (March 2021)
****************************************
The main developers this time were: SiegeLord, Peter Hull, Elias
Pschernig, Aldrik Ramaekers, Andreas Rönnquist.
Build system:
• Allow generating projects with a suffix (lorry-lee).
• Fix build under Clang-CL in Visual Studio.
Core:
• Avoid some undefined behavior errors.
• Return key modifiers in ‘ALLEGRO_EVENT_KEY_UP’ and
‘ALLEGRO_EVENT_KEY_DOWN’.
• Allow calling ‘al_map_*’ color functions before Allegro is
initialized.
• Allow minimum bitmap size to be something other than 16 on
non-Android platforms (controlled via ‘allegro5.cfg’).
• Add ‘al_get_monitor_refresh_rate’ (only implemented on Windows for
now).
Graphics:
• Fix ‘ALLEGRO_KEEP_INDEX’ flag for bitmaps.
• Add ‘ALLEGRO_OPENGL_CORE_PROFILE’ display flag.
Emscripten:
• The experimental Emscripten support (via the SDL backend) is now
documented in ‘README_sdl.txt’.
OSX:
• Move more Cocoa operations to the main thread.
• Explicitly link CoreVideo to fix the static build.
Windows:
• Issue #1125: Speed up OpenGL extension detection (Tobias Scheuer).
• Use Unicode APIs when enumerating joysticks.
• Use ‘WM_DEVICECHANGE’ rather than polling to detect joystick
hotlugging, reducing input drops and lags (Todd Cope).
• Fix joystick polling period.
• Restore WinXP compatibility by using slightly older API when
loading shared libraries (Julian Smythe).
• Fix build with HLSL disabled (Julian Smythe).
• Raise DirectInput ‘MAX_JOYSTICKS’ to 32 and ‘DEVICE_BUFFER_SIZE’ to
128.
SDL:
• Issue #1224: Fix bug in SDL voice driver.
Audio addon:
• Allows playing sounds in reverse by specifying a negative speed.
Acodec addon:
• Fix edge-case looping in Ogg Vorbis stream (Cody Licorish)
Audio addon:
• Use more sensible values for PulseAudio’s playback buffer,
potentially resolving some crashes and high CPU usage.
Native Dialog Addon:
• Migrate from GTK2 to GTK3. Sadly, we lose menu icons as GTK3
dropped support for them.
TTF addon:
• Allow initializing TTF addon before the Font addon.
• Shut-down the TTF addon automatically in ‘al_uninstall_system’.
PhysFS addon:
• Fix handling of native path separators.
• Stop using deprecated PhysFS API.
Primitives addon:
• Fix segfault in ‘al_draw_ribbon’ when ‘num_segments > 128’ (Rodolfo
Borges).
• Issue 1215: Correctly handle small scales when determining
subdivision level for high level primitives (Robin Heydon).
Documentation:
• Fix LaTeX errors in the generation of the reference manual PDF.
• Add links to examples into the reference manual.
• Allow pressing ‘S’ to focus the search bar in the docs.
• Assorted documentation improvements.
Misc:
• Add a security policy and an associated private security mailing
list - allegro-security@lists.liballeg.org.
• Add Emscripten-powered examples to
https://liballeg.org/examples_demos.html.
Examples:
• ‘ex_audio_simple’ now displays instructions and supports
bidirectional looping.
• Add default files to some audio examples.
Allegro is a cross-platform library mainly aimed at video game and multimedia
programming. It handles common, low-level tasks such as creating windows,
accepting user input, loading data, drawing images, playing sounds, etc.
and generally abstracting away the underlying platform.
