What's New in Power20
Version 4.9.5:
- The fonts in the directory and debugger window are now scalable, to accomodate high-res screens, where 9-point Monaco is simply to hard to read.
- Sound Output is broken on some Macs. This used to cause extremly fast emulation in Power20. While the root cause of this bug is still not understood, Power20 now detects the problem and safely falls back to mute emulation.
