      Release Notes: The command line front end is now able to call an assembler (-S to disable). Package includes more examples. This release supports multiple pages of Program memory. New functions added: sleep() (makes the PIC sleep) and on_interrupt() (called on any enabled interrupts). The asm() function now has internal parser that adds code for selecting banks, and requires only assembly code (the previous format is still enabled). Better support of ICD. Support has been added for loops from 0 to 255, including 255. There are some bugfixes.
