Jun 21, 2008
    Added BLEND_RGBA_* special flags for blit, and fill.

    Reworked locking code. Locks are now more strict and can only be
    removed by the object(s), that caused them.
    New Surface.get_locks() method, which returns the currently existing
    locks.
    [BUG] Fixed Surface.get_locked() bug for Surfaces which do not
      require locking, but have third-party locks attached.
    
Jun 13, 2008
    [BUG] Fixed bug with mixer.get_init() Thanks Frankie Robertson!
    [BUG] Fixed long alpha overflow bug in Surface.set_alpha().

    updates to the sprite.py collision functions that update them to match 
        the modules coding style, include appropriate comments, and are 
        about 20% faster. It also includes a collide_circle_ratio function 
        for completeness, and perhaps most importantly, fixes a bug in 
        colide_mask which kept it from working correctly.  Also added unittests
        for the collision functions.  Thanks John Krukoff!

    [BUG] sound crackles on windows; restored chunk size 
        calculation to pre 1143

    Added \#!/usr/bin/env python to the top of examples that didn't have it.

    New PixelArray.compare() method to compare two PixelArrays.

Apr 8, 2008
    [BUG] Fixed pygame.draw.aaline() for cases in which only a single point
        has to be drawn.

Apr 4, 2008
    New PixelArray.replace() and PixelArray.extract() methods to quickly
      replace or extract a certain color.

Apr 3, 2008
    Added iter support to PixelArray.

Apr 2, 2008
    [BUG] Fixed mask settings for 8-bit surfaces created by
        surfarray.make_surface()
    [BUG] Fixed integer color value assignment bound checking in PixelArray.

Mar 30, 2008

      to create a new surface from the PixelArray view.
    Fixed mask namespace pollution and docs.

release_1_8_0release

    Updated credits.
    Mac OSX binary now has movie module working.
    1.8.0rc5

    the play functions of mixer.Channel and mixer.Sound both now take keyword
      arguments, and accept a fade_ms argument that makes the sound fade in
    
Mar 9, 2008
    pygame.display.set_mode() will now respect the screen resolution settings
      for the width or height set to 0 as supported by SDL >= 1.2.10. 
      Thanks Lorenz Quack!

Mar 5, 2008
    [BUG] Stopped releasing GIL on png, and jpeg saving functions because
        they do not seem to be thread safe.

    [BUG] A work around for 8 bit samples being stereo reversed with SDL_mixer.
        Also check the return value of Mix_SetPanning, and raise an 
        error on volume errors.

    [BUG] Changed default chunk size for pygame.mixer to 1024*3.  Which is 
        the magic number which stops scratchy sounds on most systems.  
        However it does make sounds a bit laggier... it's best provided as 
        a config item for users.

    Updated pygame.display.update() to release the GIL whilst doing things,
        so other threads can do things whilst it's updating the screen.

    Some comments to help Mac OSX people installing, and compiling pygame.
        About bdist_mpkg in setup, and also fixed an exception message 
        to be nicer about requiring pyobjc.

Mar 3, 2008
    [BUG] Fixed up pygame.mask.from_surface, got color key, and perpixel alpha 
        modes reversed.

    Also added better test to the mask test.  
        Also it wasn't testing pygame.mask.from_surface at all!

    Added pygame.sprite.collide_mask to join the mask_* collision functions.  
        Started adding test for pygame.sprite.spritecollide.


Feb 19, 2008
    Added Surface.get_bounding_rect() method, which returns the smallest
    rect for the surface, that contains visible (non-transparent) data.

Feb 14, 2008
    Updated constants GL_SWAP_CONTROL,GL_ACCELERATED_VISUAL,BUTTON_X1,BUTTON_X2

    Added pygame.key.get_repeat to see how holding keys down repeats.  This is
      the sister function of pygame.ket.set_repeat.

    MacOSX, and Windows binaries now use latest SDL 1.2.13

Feb 11, 2008
    An example of using pygame with no windowing system.  Useful for webserver
      scripts, or for little utilities.

    Updated mac_scrap to pass some tests, and raise NotImplementedError 
      otherwise.

    Further Windows build updates:
      For MinGW/MSYS the build process now finds the MSYS and MinGW
      directories automatically. gcc links to msvcr71.dll without
      requiring changes to the gcc specs file. This makes the build
      process GCC Version 4 ready. By default all DLLs are Win32 GUI,
      but can be console. The build progams will run from either the
      Windows or MSYS terminal.

      Fixed a bug where DLLs were not installed in the package directory.
      For Windows, everything now goes into the package directory.

      build_deps.py renamed to msys_build_deps.py to avoid confusion.

Jan 26, 2008
    pygame.sndarray noew can change between Numeric and numpy using the
      new methods pygame.sndarray.use_arraytype () and
      pygame.sndarray.get_arraytypes ().

Jan 24, 2008
    Updated the configuration and build process under Windows. In
       config_msys.py and config.py os.popen is replaced with the newer
       subprocess.Popen so the MSYS will run. Calls to raw_input now
       show the prompt on an MSYS console. In an MSYS build paths
       written to Setup are now Windows paths for distutils. The hard
       coded DLL file paths have been removed from setup.py.  It now
       gets the paths from Setup. Consequently, setup.py is now VC/MinGW
       agnostic.

    Added build_deps.py, an all-in-one dependency builder for
       Windows. Requires MinGW and MSYS.

Jan 8, 2008
    pygame.surfarray now can change between Numeric and numpy using the
       new methods pygame.surfarray.use_arraytype () and
       pygame.surfarray.get_arraytypes ().

Jan 4, 2008
    Removed Numeric compile time dependency.
    Added numpy surface array support.

Dec 31, 2007
    New method pygame.get_sdl_byteorder () to get the SDL byte order.

Dec 15, 2007
    Mask can now get bounding rects of set bits.
    pygame.transform can find edges in an image, get the average surface
      of many surfaces and also threshold an image by color.

Sep 1, 2007

     BufferProxy - which is a buffer interface only class.  Thanks Marcus!

Aug 23, 2007

    PixelArray from Marcus.  It's going to be a replacement for surfarray.
    [BUG] Fixed some bugs in Surface with SRCALPHA and input validation.
        Thanks Lenard Lindstrom and Brian Fisher.

Aug 15, 2007
    The sprite module has had some big changes from DR0ID.  It now has a 
     LayeredUpdates, and LayeredDirty groups.  For using layers when
     rendering the sprites.  LayeredDirty is an alternative to 
     RenderUpdates that automatically finds the best display method
     (either full screen updates, or dirty rect updates).  It's faster
     if you have sprites that don't move.  Thanks DR0ID!
    Added pygame.mask.from_surface which can make a Mask object from
     a surface.  It's 128x faster than the python version!
    pygame.movie bug fix. Thanks Lenard Lindstrom!

Jun 25, 2007

    Fixed some documentation.  mask, scrap, font modules.

      Thanks piman!
    surface.fill() now takes the same BLEND_ADD BLEND_SUB etc flags that
      surface.blit() takes.  Which makes fade to white, and fade to black
      type operates simple and fast.  Thanks Marcus!!  
    Added the GL_SWAP_CONTROL constant from SDL.  Thanks Eyal Lotem!
    Added the new blitters from Marcus.  These speed up the blend functions
      and the alpha blit function.
    Added a -warnings flag to setup.py for extra warnings with gcc.
    A fix from Marcus for the scrap module in X11.

May 9, 2007

    A cursors.py example from Kamilche.  Thanks!

February 11, 2006
    Changed the behaviour of Clock.tick to use SDL_Delay instead of a busy 
      loop.  Added a tick_busy_loop which uses the old behaviour.  This 
      is more consistent with what people think Clock.tick() will do.
      That is, not use 100% cpu to get more accurate timing.
    testsprite.py example, which is based off the testsprite.c in SDL
      shows the performance of sprites, and is a good test.
    Added gp2x package which contains some constants for the gp2x buttons.
      This will be where gp2x specific functionality will live.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
