NEWS:

• I released version 0.46 on 20 January 2013. It re-optimizes ARM and THUMB support, adds THUMB2 support, and partial implementations of 65c816 and MIPS16.
• I released version 0.45 on 9 November 2010. It improves z80 support and has the start of 8051 support.
• I released version 0.44 on 21 October 2010. It improves z80 support.
• I released version 0.43 on 13 October 2010. It improves 8086 support.
