high level programming language and compiler targeting 6502 machines such as the C-64 and CommanderX16
It is now possible (and required) to assign all values returned from a romsub/asmsub that returns multiple values.
The void keyword can now also be used in a new way: as a dummy assignment target for any value you are not interested in in such a multi-value assignment.
Please read the documentation in the manual for details about this new feature.
verafx.mult() and muls() now return both words of the 32 bits resultsprites module: the palette_off set parameter now takes values 0-15 (instead of 0-255) to be more consistent with docs and vera behaviortxt.cls() as a shorter alternative to clear_screen()

floats module: atan2, secant, csc and cot.Full Changelog: https://github.com/irmen/prog8/compare/v10.2.1...v10.3
Bugs fixed:
Library changes:
-nostrictbool command line option that allow implicit conversions between bool and bytes again. This allows prog8 to compile most older code without source changes. Note that this option will likely be removed in a future version, so it's advised to actually go update your program code to be properly compatible with the new version.
Full Changelog: https://github.com/irmen/prog8/compare/v10.1...v10.2
Bug fix release. Please upgrade if you're using 10.0 because a handful of important fixes have been made.
Also added cx16.get_program_args() and cx16.set_program_args(), and made a couple more code generator improvements.

This is a BIG release. Many things got changed, improved or fixed.
additional rules for symbol prefixing to avoid name clashes in the generated assembly code. Details here https://prog8.readthedocs.io/en/latest/technical.html#symbol-prefixing-in-generated-assembly-code
push, pushw, pop and popw are no longer builtin functions but regular inlined subroutines in sys.
some floating point routines have been renamed to make the names more consistent:
floats.rndf -> floats.rnd
floats.parse_f -> floats.parse
floats.rndseedf -> floats.rndseed
floats.print_f -> floats.print
floats.str_f -> floats.tostr
some type casting rules have been tweaked. You may have to add or remove type casts in certain places.
boolean logical "and" and "or" expressions are now evaluated with McCarthy / short-circuit evaluation. This means that not every term in the expression will be evaluated if the result can already be determined! This should normally not cause any problems because it is bad practice to write code that depends on the order of evaluation of the terms, but sometimes we can't help ourselves.
