Release history:

2.4q5 -- 29 December 2015

allow whereis() on variables
fix whereis() in expressions

2.4q4 -- 25 December 2015

fixed large lookup tables
fixed data error with inline assembly on hybrid chips
fixed error when using lookup tables in expressions on 16 bit chips

2.4q3 -- 27 September 2014

fixed exponent adjust when floating multiply/divide by an integral power of 2
allow exponent adjust when floating multiply/divide by a floating power of 2
allow negative numbers in exponent adjust
fixed some documentation types and examples (thanks Rob!)
fixed the float_to_ascii routine to be more useful
floating point constant folding was broken

2.4q2 -- 23 January 2014

fixed floating point constant 0
incorrect movlp_nop usage
fixed branching optimizer on conditional branch
fixed bug in pic_multiply_create_fn16

2.4q -- 13 November 2013

don't allow bit offset placement to non-bit variables (var BYTE x at y:2)
allow `VAR xx AT rec['.'member]['['subscript']']...'
allow non-bit variables to declare byte offets (VAR BYTE x AT y + 2)
fixed and returned an optimization that reduces code size when an empty if block is found: IF cond THEN END IF (thanks Albert!)
minor optimization. In this sequence: `movwf val; movf val,w' remove the second as redundant. This happens with the `pass result in w' and `return result in w' code.
an inline assembly move to a constant location did not set the data bits correctly (movwf 0x90).
assign from constant was completely munged in most cases
fixed documentation errors (thanks Rob!)
expanded documentation for records
minor code generation optimization in equality operators
beginning of floating point support
fixed an error that caused false positives with branch errors
clear out last multiply/divide values when branching
always inline some multiplies on the 16 bit cores
fixed a problem in binary AND and binary OR when val1 is shared and val2 is not *or* dst is in a different bank than val2
parsed assignment within a procedure definition (default parameter) but default parameters are not allowed. (Rob)
re-ordered some optimizations for tigher code (Michael)
detect if a function is declared but not defined
when assigning from a pointer of smaller type, the calle to extend the sign was missing (Michael)
variables manually placed in shared regions must have the SHARED flag set (this is internal to the compiler. A variable allocated in a shared region will now act correctly. Formerly, the shared attribute was missing in this case.)
fixed variable allocator
fixed SHARED testing in the event that part, but not all of a variable is shared
cleaned up new warning from gcc 4.7.2
fixed string constant initialization when the string contains an embedded '\0'
16 bit inline multiply did not setup indirection correctly
added `asm reset'
for _usec_delay, if the PIC temporary varaiable is in shared space, emit NOP instead of the datahi/datalo instructions.
fixed data skip errors.
upcasting a constant value causes incorrect code to be generated
fixed MULF (thanks again Michael).
fixed a bug in the skip conditional optimizer (thanks again Michael)
cmd_analyze() didn't handle assembly properly
inline assembly, using the `bank' prefix doesn't work correctly on the 14 bit hybrids
fixed stack depth reporting
fixed w optimization removals
