Fix #140 and #138 (https://github.com/PPvG) - Fix: Handle relative paths of bootloader file while burning bootloaders. Fix #126 and #142 (https://github.com/sej7278) - New: Add `CONTRIBUTING.md` explaining how to contribute to the project. +- Force -Os optimization for SoftwareSerial. Add `OPTIMIZATION_FLAGS` and `DEBUG_FLAGS`. ### 1.0.1 (2013-09-25) - Unconditionally add -D in avrdude options.
