Changelog

Sourced from rsa's changelog.

Version 4.9 - release 2022-07-20

• Remove debug logging from rsa/key.py (#194).
• Remove overlapping slots in PrivateKey and PublicKey. (#189).
• Do not include CHANGELOG/LICENSE/README.md in wheel (#191).

Version 4.8 - released 2021-11-24

• Switch to Poetry for dependency and release management.
• Compatibility with Python 3.10.
• Chain exceptions using raise new_exception from old_exception (#157)
• Added marker file for PEP 561. This will allow type checking tools in dependent projects to use type annotations from Python-RSA (#136).

Version 4.4 & 4.6 - released 2020-06-12
