<p>The main developers this time were: Trent Gamblin, SiegeLord, Elias
Pschernig.</p>
<p>Core:</p>
<ul>
<li><p>Fix OSX backend on OSX 10.10 (lordnoriyuki).</p></li>
<li><p>Simplify how sub-bitmaps interact with their parent bitmaps. You
can now destroy a sub-bitmap at any time (not only before the parent is
destroyed). Additionally, when the parent is converted using
<code>al_convert_bitmap</code>, all the sub-bitmaps are also
automatically converted.</p></li>
<li><p>Switch to using unicode Win32 (e.g. this fixes using
<code>al_set_window_title</code> with unicode strings).</p></li>
<li><p>Add some Linux WM hints so make Allegro windows work more
smoothly (especially with Unity).</p></li>

</ul>
<p>Graphics:</p>
<ul>
<li><p>Add block compression pixel formats
(ALLEGRO_PIXEL_FORMAT_COMPRESSED_RGBA_DXT1/DXT3/DXT5) for compressed
video bitmaps. This includes an API to fetch compressed block size
(<code>al_get_pixel_block_width/height/size</code>) as well as API to
load and unload compressed bitmap data without paying a runtime
compression cost (<code>al_lock_bitmap_blocked</code>). Unfortunately,
due to patent concerns this last feature is disabled for OpenGL (if you
thinks those concerns don’t apply to you, you can enable it by passing
<code>-DWANT_OPENGL_S3TC_LOCKING=1</code> to cmake).</p></li>
<li><p>Make real fullscreen modes work on OS X again. May not be perfect
still. (thanks to SDL).</p></li>
</ul>

3.1).</p></li>

‘joystick’ is still the first joystick. Supports two analog sticks and
10 buttons (A B X Y L1 R1 DPAD_L DPAD_R DPAD_U DPAD_D). Supports
hotplugging and theoretically multiple joysticks (needs
testing).</p></li>

Reynaldo).</p></li>

<ul>
<li>Add multi line text output for the font addon
(<code>al_draw_multiline_text</code>,
<code>al_draw_multiline_textf</code> and
<code>al_draw_multiline_ustr</code>).</li>
</ul>
<p>Primitives addon:</p>
<ul>
<li>Fix some sharp-angle polyline drawing bugs.</li>
</ul>
<p>Examples:</p>
<ul>
<li><p>New examples: ex_compressed, ex_font_multiline.</p></li>
<li><p>ex_dir: demonstrate <code>al_for_each_fs_entry</code>.</p></li>
<li><p>ex_haptic2: demonstrate hotplugging.</p></li>

<h1 id="changes-from-5.1.5-to-5.1.6-march-2013">Changes from 5.1.5 to
5.1.6 (March 2013)</h1>
<p>The main developers this time were: Trent Gamblin, Paul Suntsov,
Peter Wang.</p>
<p>Core:</p>
<ul>
<li><p>Fix use of clobbered return value from setlocale() on
X11.</p></li>
<li><p>Register system interface even if no display driver available on
Windows.</p></li>
<li><p>Fix use of double math functions for float arguments (Nick
Trout).</p></li>
</ul>
<p>Shaders:</p>
<ul>
<li><p>Revamped shader API. The shader API is now part of the core
library, and the shader addon removed.</p></li>
<li><p>Shaders are now a per-bitmap property, set with al_use_shader. A
bitmap without a set shader uses a default shader internally, that
allows Allegro drawing functions to work as in non-programmable pipeline
mode.</p></li>
<li><p>Shader variable setters operate on the shader of the target
bitmap.</p></li>
<li><p>Rename ALLEGRO_USE_PROGRAMMABLE_PIPELINE to
ALLEGRO_PROGRAMMABLE_PIPELINE.</p></li>
<li><p>Rename al_link_shader to al_build_shader.</p></li>
<li><p>Remove al_set_shader.</p></li>
<li><p>Remove the al_set_shader_*_array functions. These functions
cannot be easily (or at all) implemented with the D3D backend.</p></li>
<li><p>Add al_get_shader_platform and
al_get_default_shader_source.</p></li>
<li><p>Remove al_get_opengl_program_object,
al_set_opengl_program_object, al_get_direct3d_effect,
al_set_direct3d_effect.</p></li>
<li><p>Remove Cg shader backend.</p></li>
<li><p>Add macros for shader variable names (Jon Rafkind).</p></li>
</ul>
<p>Displays:</p>
<ul>
<li><p>Made al_get_display_mode return the closest thing to a pixel
format possible with the WGL driver (tobing).</p></li>
<li><p>Move WGL context destruction out of the message pump thread and
into the user/main thread.</p></li>
<li><p>Allow command-tab to work in fullscreen window mode on OS
X.</p></li>
<li><p>Remove “user_reload” parameter from
al_acknowledge_drawing_resume.</p></li>
<li><p>Don’t crash in al_create_display if there is no display
driver.</p></li>
<li><p>Don’t crash at shutdown if there is no display driver
(Windows).</p></li>
<li><p>Don’t fail init if both D3D, GL drivers unavailable
(Windows).</p></li>
<li><p>Sync bitmaps before resizing display to prevent changes being
lost after the resize (D3D).</p></li>
<li><p>Load the D3D9X module during display creation and unload it when
the D3D system shuts down.</p></li>
<li><p>Run fullscreen toggle on main thread (OS X).</p></li>
<li><p>Destroy the backbuffer bitmap when destroying the display (OS
X).</p></li>
<li><p>Switch to new NSTrackingArea API (OS X).</p></li>
<li><p>Set ALLEGRO_NO_PRESERVE_TEXTURE on backbuffer (OpenGL).</p></li>
</ul>
<p>Graphics:</p>
<ul>
<li><p>Let al_destroy_bitmap implicitly untarget the bitmap on the
calling thread.</p></li>
<li><p>Fix a bug where bitmap locking may change the target bitmap but
not restore it back to NULL (OpenGL).</p></li>
<li><p>Use memory bitmap drawing when either bitmap is locked
(OpenGL).</p></li>
