What's new in this version:

Library
- Module-level turtle functions no longer raise TclError after closing the window.
- Warnings now are raised when group references and conditional group references are used in lookbehind assertions in regular expressions.
- Multibyte codecs with custom error handlers that ignores errors consumed too much memory and raised SystemError or MemoryError. Original patch by Aleksi Torhamo.
- io.FileIO() called flush() after closing the file. flush() was not called in close() if closefd=False.
- Fixed pydoc failure with non-ASCII files when stdout encoding differs from file system encoding (e.g. on Mac OS).
- Remove RC4 from the SSL module’s default cipher list.
- Fix pydoc.synopsis() and pydoc.apropos() on modules with empty docstrings.
- Fixed arbitrary code execution vulnerability in the dbm.dumb module. Original patch by Claudiu Popa.
- Fix mishandling of absolute Windows paths with forward slashes in pathlib.
- Fixed compression in tarfile CLI. Patch by wdv4758h.
- Fix possible overflow in Windows subprocess creation code.

Build
- pydebug builds now use "gcc -Og" where possible, to make the resulting executable faster.
