0.94
Changes:

(with DIR)
- fixed notification of operating modes on the CC2420 for duty cycle calculation, etc.
- fixed status register update bug (byte/word problem)

0.93
Changes:
- removed tick based component support from MSP430 core
- re-implemented USART to be event based instead of tick based
- fixed bug in ADC12 subsystem that caused lots of events to be
scheduled back in time (causing other subsystems to get
delays on their events...)
- fixed RadioWrapper for backward compatibility with PacketListener
(for the CC2420).
- fixed ADC12 to turn off event scheduling when ADC12 is not on anymore

0.92
Changes:
- fixed bug with a write register which did not handle word/byte
- fixed bug which caused array out of bounds on IO-units.
- fixed bug in timer causing interrupts when timer was stopped
- fixed bug in timer to handle start/stop better
- fixed bug in MSP430 core that caused MOV instruction to change status flags
- added getDoubleValue in DataSource and made "duty" command print
duty cycle information as double instead of int
- fixed windows to accept double input and not only int input
- corrected cycle count on some instructions
- improved CC2420 emulation (thanks to Matt Thompson)
- added Telos platform including AT45DB flash memory chip (Matt Thompson)
0.91
Changes:

- added configuration system
- added connectivity between multiple running mspsim's
- bugfix in instruction emulation thanks to Matt Thompson
(addressing mode - autoincrement byte wrong on PC).
0.90
Changes:
- fixed multiplier to handle the different modes better.
- refactored so that IOUnit is no longer a Chip
- added statistics commands and an exec command to the CLI
- implemented better support for statistics (operating mode)
- fixed interrupt handling bugs in IOUnit
- added API for accessing frequency/channel and output power in CC2420
