v2.0

Enhancements:

• Macros can now call other macros, with a maximum depth level of 8 #100
• Length of a label can now be 64 characters #102
• Going forward, only LOCAL labels will be allowed inside a macro body. Local labels are internally expanded with a 'macro expansion ID' to create a unique macro-expansion scope that will also work during recursive macro invocations #103
• -m option now allows for minimum memory buffer configuration to assemble large programs on the Agon #105
  Large programs like the ez80asm version of BBC Basic can now be assembled directly on the Agon
• Macro arguments mappings are now displayed during listings #107
• ALIGN statement at end of file / between DS statements at the end of a file no longer producing unnecessary fillbytes #109
• Macro arguments not longer accepted when name of argument is a valid number #116
• Macro bodies are no longer limited to 2K per macro #117
• Processing 'depth' maximum is raised from 4 to 8 to allow for deeper include levels used in larger programs #119
• Support for a CPU directive, to limit the opcodes to Z80/Z180 #120
• Labels and instructions are accepted without preceding spaces #121
• Support for a relocatable code block using the .relocate directive #122
• General cleanup of older code, improved code readability
• Much Improved error handling

Fixed since previous release:

• -v option quits without throwing an error #101
• Extremely low memory situations on the Agon didn't always correctly produce an 'Out of memory' error, while the program doesn't exit in an orderly fashion #104
• Macro call failed using an EQU as an input parameter #106
• -x option incorrectly displayed output size #108
• Using comment ';' immediately after macro command without arguments resulted in error 'Incorrect number of macro arguments' #110
• Expressions with compound escaped literals resulted in an error #111
• Commented single quoted literal produced an error #112
• Missing first data value in DB/DW/DW24/DW32 list was not detected #113
• incbin/include without argument didn't provide an error, program crashed #114
• including files with long filenames could lead to a crash, when the file couldn't be opened / didn't exist #118
• Removed excessive empty lines in a listing file with windows builds #123

v1.11

New in this release

• Support for prioritized operations using [ ] bracketed expressions
• Small code improvements and optimizations
• Compiled with AgDev v3.1.0

A number of small fixes in this release

• .DS directive didn't report fillbytes in listing #89
• Using long filenames as macro arguments caused aborts #90
• Updated documentation to reflect order of operations #91
• Updated documentation to reflect if/endif behavior #92
• The asciz directive always emitted a 0 in any conditional block #93
• Labels weren't always handled correctly in a condition if/endif block #94
• -v flag continued with assembler actions #97
• Multiple operators without a number/label identifier in between didn't flag an error #99

v1.10

Bugfixes:

• Fix for Issue #87 - now correctly handling operator statements during a macro expansion with data statements
• Fix for Issue #88 - now correctly handling data statements enclosed in a conditional if/else/endif block.

New features:
All assembler directives enclosed in if/else/endif directives are now respected. If/else/endif still cannot be nested.

v1.9

Fixes:

• Fix for issue #86 - .org directive can now be used multiple times with automatic padding using the currently defined fillbyte

v1.8

Fixes:

• Buffer overrun on strcpy in parse_operand #84
• Macro expansion at a label line ignores label definition #85

v1.7

Enhancements:

• Additional context provided at warning/error levels - Macro error messages are unhelpful #82
  Fixes:
• Negative numbers error during macro expansion #81

v1.6

Enhancements:

• Possibility to set ADL offset for non-ADL code #78

Fixes:

• Loading a ',' literal produces an error #76
• .DS directive should only define empty space #79
• Always return code 0, as MOS only supports non-posix error codes, avoiding the way AgDev works around this

v1.5

Starting release 1.5, ez80asm only supports MOS versions that provide /bin/ folder support for command execution, such as Console8 MOS 2.2.0+. This removes the need for the assembler to use and maintain a MOSlet loader, while providing extra memory to the assembler in the 0x0B0000 - 0x0B7FFF (MOSlet) memory area.

v1.4

This release shows a significant (+/- 40%) performance increase, due to a number of internal changes, specifically

• Storing local labels in memory, expanding them into the global label space, not requiring file I/O for local labels
• Buffering all source files in memory, not needing to re-open/fseek them in pass 2
• A re-implementation of macros, buffering all macros in memory instead of in files
• Not looking up values/labels during pass 1, when their value wouldn't make a difference in the length/addressing of the binary output, saves a significant amount of processing

Performance might not be relevant when the assembler is running on a modern PC, but running natively on the Agon platform this upgrade is really noticeable.

Fixes:

• Better reporting of macro errors during macro expansion; reporting in which file and on what line the macro expansion has an error
• Macro expansion issue with indirect operands #74

v1.3

Stability release, mostly resolving a number of smaller issues in error reporting, but also fixing some bugs.
Thanks to everyone who reported issues and helped tracking them down.

Fixed in this release:

• Presence of just a single '' in a string isn't always detected as an error, sometimes ignored during emission #57
• Failure to detect missing source operand #58
• Failure to detect single shift character as operator (< or >) #59
• Failure to detect missing operand after operator #60
• Parsing errors not displaying correctly #61
• macro issue (seen on v1 and 1.2) random - line 1 - Invalid number format (other issues also pointing toward not opening Include files seen) #62
• fillbyte directive defective #63
• blk* defines not using fillbyte, if no explicit init value given #64
• Macro expansions not correctly allowing comments #65
• Labels named as a valid number, aren't marked as invalid label #66
• Defines missing an operand aren't correctly reported as error #67
• Missing ADL statement after assume directive crashes assembler #68
• Missing value after equ statement crashed the assembler in some cases #69
• Missing value after if crashes the assembler #70
• String type definition with dw/dl/dw32 has incorrect error #71
• Incorrect negative bounds checking in data directives for 8/16/24 bit values #72
• 32bit values in DW32/BLKL not emitting MSB correctly #73
