Arduino 0022 is now out. Mostly bug fixes and optimization. A few additions/improvements of interest to us:
- Fixed EEPROM library on Mega 2560.
- Adding an SD card library based on sdfatlib by Bill Greiman and the MemoryCard library by Philip Lindsay (follower) for SparkFun.
- Building the user sketch before the core or libraries, so errors appear faster.
- Hardware serial receive interrupt optimization.
- Remembering serial monitor window size and line ending selection.
- ....and a bunch of others you can see here
