New:

• We have a website! Accordingly, HTML documentation is no longer distributed in the source or in the release artifacts below. All old documentation links now redirect to the latest release's documentation
• You may also have noticed the repo has been moved to gbdev instead of rednex! Don't worry, the same people are in charge.
• /* Block comments! */
• Whitespace is now allowed between the brackets in [bc], [de] and [hl], also allowing [\1] to work.
• The second number argument to INCBIN can now be omitted, going up to the end of the file
• The argument to rb and rw is now optional, defaulting to 1
• RGBASM and RGBLINK can both use stdin as input, and stdout as output (support yet to come to RGBFIX)
• zsh completion scripts are available in the contrib/ folder. (If you want to make bash ones, apply in #620)

Changes:

• Nested macros are now invalid, but a workaround is possible
• The lexer has been fully rewritten, which should make additions to it easier, and improve performance
• Removed arbitrary limits on charmap size and name length
• STRSUB will no longer warn when taking 0 characters at the end of the string
• RGBLINK will no longer report errors stemming from other errors
• RGBASM is now able to write more jrs without relying on RGBLINK, leading to smaller .o files and faster linking
• INCBIN should produce a slightly more useful error message
• A bunch of quality-of-life improvements for downstream packagers, especially using CMake
• Assertions have been removed from release builds, improving performance slightly
• charmaps now allocate memory as nodes are allocated, greatly reducing their size (by a factor of ~8)
• Documentation now mentions that SHIFT updates _NARG

Fixes:

• Two 6+ year-old crashing bugs have been fixed. They were thankfully rare, but should no longer be a problem now.
• LOAD blocks could produce incorrect output when at the beginning or end of a section
• __FILE__ caused syntax errors if the file name contained a quote
• jr in certain circumstances could crash RGBLINK
• Fixed inconsistent version numbering between the Makefile and the CMakeLists
• Documentation failed to mention SECTION FRAGMENT
• Documentation incorrectly listed bit 7 of symbol type as being the unionized section flag, and failed to mention the section fragment flag
• Documentation erroneously used to claim that symbol names could begin with a digit
• Error out when using align outside of a SECTION, or when using shift outside of a macro... instead of crashing
• Fixed a potential RGBASM crash with very large expressions
• Fixed overwriting a builtin symbol succeeding after insisting enough
• Fixed a crash when subtracting two invalid labels
• Fixed using _NARG outside of a macro crashing RGBASM

Note to Windows users

Release 0.4.1's binaries were compiled with MSVC instead of MinGW, giving apparently better results. Unfortunately, there is currently a problem with MSVC (not that we can do anything about it, yay!), so the binaries below are MinGW again. 0.4.3 should be compiled with MSVC again, though.
