Release v1.1.0rc1 · msgpack/msgpack-python

Update Cython to 3.0.10 to reduce C warnings and future support for Python 3.13.
Stop using C++ mode in Cython to reduce compile error on some compilers.
Packer() has buf_size option to specify initial size of internal buffer to reduce reallocation.
The default internal buffer size of Packer() is reduced from 1MiB to 256KiB to optimize for common use cases. Use buf_size if you are packing large data.
Timestamp.to_datetime() and Timestamp.from_datetime() become more accurate by avoiding floating point calculations. (#591)
The Cython code for Unpacker has been slightly rewritten for maintainability.
The fallback implementation of Packer() and Unpacker() now uses keyword-only arguments to improve compatibility with the Cython implementation.
