-
  1. MacOSX build is working again. It's still rough but Tetris works on it now. dngor++
    2. -
  2. SDL::Tutorial::Tetris is on CPAN as v0.15. nferraz++
    3. -
  3. SDL Perl docs are a little better now. magnet++
    4. -
  4. Finally experimental Rect and Game::Rect are behaving. There is still more work needed in Game::Rect. Moreover there are more tests on the experimental release. garu++
    5. -
  5. Also POGL is working experimentally with SDL.
    -
    6. -
Hopefully I can get the first three results into the next release soon. The next release 2.2.3 will go up as a developmental release first. Also the experimental branch is going up as version 2_4.

-in the Docs for the SDL Perl Team section.
+So I have been hacking for a while on SDL::Events::set_event_filter. The code below is an example usage. The magic behind this is here

Tinker with $filter and look at perldoc lib/SDL/pods/Event.pod. 
 
Have fun,
