 2.0.4
+* Switch to new and improved compiler toolchain - now get informative errors if sketch is too big on parts that use RJMP, bugfix for eeprom.h (not to be confused with EEPROM.h), various header improvements (board manager install only).
 * Improve naming of exported binary and assembler listings - now includes every setting that could impact the output!
 * Fix failure to export compiled binary on some linux platforms (#201)
 * Massive doc improvements.
 * Improve backwards compatibility of Wire.h (#203)
 * Fix strange bug in EEPROM.h that was somehow missed 
 * Mark unqualified BOD settings that were removed from datasheet as unofficial, add warning that they may not work correctly (but suspect will be close - they were working for me before I realized they were unsupported! they were listed in io.h before!), and add Microchip's guaranteed operating speeds + BOD levels per datasheet to documentation.
-* Switch to new and improved compiler toolchain - now get informative errors if sketch is too big on parts that use RJMP, various header improvements (board manager install only).
