11 | What's new |
12 | ========== |
13 | |
14 | 0.5: patched sound for real stereo (using NK's solution); better init code. |
15 | |
16 | 0.4: lots of cleanups; sound is threaded now, double buffered too; 8 bpp video support; better exiting code. |
17 | |
18 | 0.3: shorter library; improved joystick diagonal detection. |
19 | |
20 | 0.2: better code layout; public release. |
21 | |
22 | 0.1: beta release |
