Release history:

2.4n -- 2 June 2010

added inline assembly statement mulwf (thanks hawkdavid52)
pic_value_is_zero doesn't work with pointers (bugreport_20100502)
broken arrays passed to functions (bugreport_20100523)
fixed `asm bank ' for 16 bit cores
Implicitly created pseudo-variables must be created in the same block as the true variable (bugreport_20100506).
On the 16 bit cores, if a pseudo-variable is implicitly created, the l_main label is somehow deleted causing the generated code to not work.
minor optimization when using 'case' with bit values. assign the bit to a temporary first to avoid shifting/masking for each case.
'case 0' on a multi-bit variable fails
Added 14 bit hybrid support (thanks Rob!)
Fixed the defined() operator to return a bit (as documented) so no more warnings or need to compare with 'true'
Issue a diagnostic if a value overflows a UNIVERSAL (is > 32 bits) (bugreport_20100424)
Allow octal constants (0q...)
In some circumstances an aliased value would get confused
Invalid assert on add with the 14 bit hybrid
The logic in UNIVERSAL value overflow was wrong, causing a spurious message in edge cases.
The MOVLB optimizer was not seeing functions only called indirectly.
Added '\\' to the language documentation.

2.4m -- 26 Dec 2009

Fixed documentation for '-include'
Added '[no-]asm', '[no-]codfile', '[no-]log', '[no-]lst' '[no-]hex'.
IF expr THEN END IF caused the compiler to crash
Software stack was not being calculated when -no-variable-reuse in effect.
Directly accessing the 0th element (ch = buf[0]) of a pointer caused either an assertion failure or a segfault
Fixed COD generation
Added ID programming support with PRAGMA ID and PRAGMA IDDATA
Added 'movlb 0' to the ISR preamble on 16 bit cores
Fixed `db' & `dw' on 16 bit cores
Fixed PC which was formerly 16 bits, but can be 32 bits on the 16 bit cores.
Restructed the archive directory layout
Converted the three major guides (jalv2, jalv2opt, jalv2pragma) to docbook format in the hopes that this will help me keep everything up to date.
EEPROM data on the 16 bit cores started at location 0 ('cause the variable created was only 16 bits, whereas eeprom on the 16 bit cores starts higher than 0xffff).
a re-entrant function taking an array parameter caused an invalid assertion failure
in some cases a SEGFAULT would occur when passing an array parameter
turned on const comparison warnings (when a comparison is always TRUE or FALSE)
turned on overflow warnings (when a universal value is used that does not fit with its counterpart)
fixed COD file generation
check function parameters for type & overflow
comparing a single bit variable and a single bit constant does not work if -no-expr_reduce is set.
emit an error if an attempt is made to create a bit array (bit arrays are not supported).
added `pragma bootloader bloader' and `pragma bootloader loader18'
fixed `pramga' --> `pragma' in the inline error message
fixed the TRIS parameters in the online manual
added `addwfc' to inline assembly
fixed aliasing at different block levels (eg, an alias in a procedure referencing a global)
