• started adding type annotations to shedskin (Shakeeb Alireeza)
• use CXXFLAGS instead of CCFLAGS in makefiles (Yuri Victorovich)
• add object address to default __repr__ (reported by Yuri Victorovich)
• FreeBSD compatibility fix (Yuri Victorovich)
• more scalable but slower type inference
• reimplemented {dict,set} using STL unordered_{map, set}
• added --float32/--float64/--int32/--int64/--int128 options
  (--int128 not available under windows, awaiting C standardization)
• fixed memory leak for extension modules
• new pycsg example (constructive solid geometry)
• fixed c64, hq2x and pylot examples under windows
• ignore typing imports and any type annotations
• support for range.{start,stop,step,count,index,__contains__}
• generalized expr in [..]/(..) optimization to work in more cases
• support bytes.__contains__(int)
• support itertools.{pairwise, accumulate}
• support default value for dict.pop
• fix {str,bytes}.{find,rfind} negative start, stop arguments
• improved support for overloading __index__
• rewrote {str,bytes}.split to not use macros
• struct.{pack_into,unpack_from}: wrap negative index
• remove partial __del__ support, and just mention it is not supported
• (re)add io.StringIO (in part to test print function)
• added print(flush) argument
• added array.typecodes
• support 'n' and 'N' fmt chars in struct module
• removed --nogcwarns and always hide gc warnings
• (re)add tests for array, io
• cleaner print statement for common (no keyword) case
• many refactorings for readability
• fixed a large amount of g warnings

• optimized indexing (when not using --nobounds, --nowrap) (thanks to folkert van heusden)
• optimized list/tuple allocation (thanks to folkert van heusden)
• improvements from running ruff linter (thanks to shakeeb alireza)
• support python 3.12 (used deprecated 'imp' module)
• optimized struct.{pack, pack_into}
• fixed several bugs in struct.pack
• added special-case optimization: list-expression [element]
• support syntax for sets: {a, b, ..}
• support for int.bit_count()
• support for zip(strict=True)
• replace usage of va_arg etc macros with variadic templates (faster and more flexible)
• removed boxing of arguments to print(), struct.pack().. cleaner and should be much faster.
• two new examples: a strong othello player, and a collatz sequence record finder
• fixed many common compiler warnings (-Wall -Wconversion.. and such)
• fix segfault on unhandled exception (ubuntu) by switching to -lgctba from -lgccpp
• various fixes for --long
• fix (translate) --silent
• fix itertools.{zip_longest, filterfalse} (renamed from izip_longest, ifilterfalse)
• various other minor fixes
• add some errors for unsupported features
• fix fysphun example to work again
• ported four examples to pygame

• Use CMake to generate output binaries (Shakeeb Alireza)
• Native Windows support! (using cmake and conan; Shakeeb Alireza)
• Dropped blessings/progressbar/jinja dependencies (Shakeeb Alireza)
• Various minor C improvements/fixes (Folkert van Heusden)
• mmap ContextManager support (Humhue)
• Basic support for f-strings (no format specifiers)
• Support relative imports
• Support walrus operator
• Support struct.{unpack_from, pack_into}
• Support unpacking from iterables
• Fix bytes.contains(bytes)
• Add DOOM-engine example (1 FPS -> 60 FPS)
• Prettify cpp tuple types ("tuple2<T,T>" -> "tuple")
• Set {Exception, BaseException}.class
• Various minor other fixes and improvements
• ...

• complete migration to python3 (and drop python2 support!)
• various code cleanups for readability
• some fixes for OSX
• reduced compiler warnings

-run shedskin itself with python 3.8..3.11 (but still only compiling python2-compatible code)
-add sunfish example
-move to c 17, allowing us to use std::hash instead of implementing our own algorithm
-optimize 'name in (expr, expr, ..)'
-optimize 'for i, c in enumerate(str)'
-add option to disable gc (-c/--nogc)
-add support for gc.enable/disable/collect
-use 1 byte for bools rather than 4
-dropped "official" windows build (suggestion to use WSL if possible)
