Allegro changelog for 5.1.x series

See changes-5.0.txt for changes in Allegro 5.0.x. These lists serve as summaries; the full histories are in the Subversion repository.

Changes from 5.1.0 to 5.1.1 (February 2012)

The main developers were: Thomas Fjellstrom, Trent Gamblin, Matthew Leverton, Elias Pschernig, Jon Rafkind, Peter Wang.

Ports:

• Thomas Fjellstrom started an Android port. Displays, keys and touch events work.

Core:

• Make al_ref_cstr, al_ref_ustr and al_ref_buffer return const ALLEGRO_USTR* instead of just an ALLEGRO_USTR* (Paul Suntsov).

Graphics:

• Fixed a bug in the OpenGL driver when drawing the backbuffer outside the clipping rectangle of the target bitmap.

Displays:

• Fixed a problem with wrong window size when restoring a minimised window, in code that was added to support window constraints (jmasterx).

• Set ALLEGRO_MINIMIZED display flag on Windows (Zac Evans).

• Prevent a deadlock during display creation on X.

• Fallback to the 'old' visual selection method on X instead of crashing if the 'new' visual selection doesn't work.

• Implement XEmbed protocol.

• Add hot plug display support on iOS (Airplay and wired.)

Input:

• Use the same logic in set_mouse_xy for FULLSCREEN_WINDOW as was used for FULLSCREEN. (Max OS X)

Audio addons:

• Add audio recording API with implementations for ALSA, AudioQueue, DirectSound8 and PulseAudio.

• Improve code to check that DLL symbols are loaded in the acodec addon. The old method was hacky and broke under -O2 using GCC 4.6.1. (Paul Suntsov)

Image addon:

• Some initial Android support.

• Write libjpeg errors to Allegro log.

TTF addon:

• Clear locked region so pixel borders aren't random garbage that can be seen sometimes with linear filtering on.

Video addon:

• Added Ogg Theora/Vorbis backend.

• Fixed a few warnings with ffmpeg version 0.7/0.8.

Build system:

• Add monolith library option.

• Detect the new MinGW cross-compiler in Ubuntu.

Examples:

• Added new examples: ex_record, ex_record_name, ex_display_events.

• ex_ogre3d: Make it work under Windows (AMCerasoli).

• skater: small bug fixes, mouse support, add missing files for scrollers.

• a5teroids: Support gamepads that report small non-zero values for sticks that are at rest.

• Added pong example in Python.

Other:

• Added index to HTML version of the reference manual.

• Various documentation updates.

• Other minor bug fixes.

Changes from 5.0.x to 5.1.0 (November 2011)

The main developers were: Michał Cichoń, Trent Gamblin, Matthew Leverton, Elias Pschernig, Paul Suntsov, Peter Wang.

Core:

• Added al_register_assert_handler.

• Added API for registering callbacks to intercept window messages on Windows.

Graphics:

• Added bitmap conversion API: al_convert_bitmap, al_convert_bitmaps, with bitmap flag ALLEGRO_CONVERT_BITMAP and display option ALLEGRO_AUTO_CONVERT_BITMAPS. Automatic bitmap conversion is enabled by default.

• Added al_draw_tinted_scaled_rotated_bitmap_region.

• Added new ALLEGRO_PIXEL_FORMAT_LUMINANCE_8 format.

• Added a new bitmap flag ALLEGRO_KEEP_INDEX.

• Separate bitmap loader flags from bitmap flags. This adds three functions: al_load_bitmap_flags, al_load_bitmap_flags_f and al_load_bitmap_font_flags.

• Add ALLEGRO_SRC_COLOR, ALLEGRO_DST_COLOR blending modes (Jon Rafkind).

• Add ALLEGRO_INVERSE_SRC_COLOR and ALLEGRO_INVERSE_DST_COLOR blending modes.

• Made al_compose_transform do a full 3d multiply.

• Added al_get_current_inverse_transform, al_ortho_transform, al_get_projection_transform, al_set_projection_transform.

• Added al_reset_clipping_rectangle convenience function.

• Added al_get_d3d_texture_size.

• Added al_d3d_set_release_callback and al_d3d_set_restore_callback for release/restoring user d3d objects.

Displays:

• Added al_get_display_orientation.

• Added a new display option ALLEGRO_SUPPORTED_ORIENTATIONS to specify the supported orientations (default is just portrait as before).

• Added al_change_display_option function, initially only for ALLEGRO_SUPPORTED_ORIENTATIONS.

• Add two new display events (only implemented on iOS right now). ALLEGRO_EVENT_DISPLAY_HALT_DRAWING tells the app to stop all drawing and ALLEGRO_EVENT_DISPLAY_RESUME_DRAWING tells it it can start drawing again. SWITCH_OUT/IN on iOS were redefined from "going into/out of background" to "going active/inactive".

• Added the function al_acknowledge_drawing_halt.

• Added window size constraint functions (jmasterx).

Input:

• Add API related to touch input. The implementation covers iDevices and Windows 7 drivers for touch input. A number of mouse emulation modes are provided.

Events:

• Add al_pause_event_queue, al_is_event_queue_paused.

Filesystem:

• Added al_fopen_slice.

• Added al_set_exe_name which allows overriding Allegro's idea of the path to the current executable.

Audio addon:

• Add mixer gain property and functions.

• Add a 'global' audio event source, generating some audio events from the Audio Queues driver: AUDIO_ROUTE_CHANGE, AUDIO_INTERRUPTION, AUDIO_END_INTERRUPTION.

Native dialogs addon:

• Add menus to native dialogs (Windows and GTK).

Primitives addon:

• Add simple polygon triangulator and polygon drawing routines.

• Added al_draw_polyline and al_draw_polyline_ex.

• Added al_draw_filled_pieslice and al_draw_pieslice.

• Added al_draw_elliptical_arc.

TTF addon:

• Added al_load_ttf_font_stretch functions (tobing).

Shader addon:

• Added a shader addon and programmable pipeline support.

Video addon:

• Added a video player addon, currently using ffmpeg.

iOS port:

• Added al_iphone_override_screen_scale, al_iphone_get_screen_scale, al_iphone_set_statusbar_orientation, al_iphone_get_last_shake_time, al_iphone_get_battery_level, al_iphone_get_window, al_iphone_get_view.

Examples:

• Added new example programs: ex_audio_chain, ex_loading_thread, ex_menu, ex_palette, ex_polygon, ex_shader, ex_window_constraints, ex_video.

• Added skater demo ported from Allegro 4.4.
