This upgrade from version 47.0.0 to 49.0.0 spans two major versions and introduces significant breaking changes, including dropping support for older Python and OpenSSL versions, removing algorithms, and enforcing stricter API validation.

Key Breaking Changes:

• Python Version: Support for Python 3.8 was removed in version 48.0.0. This upgrade requires Python 3.9 or later.
• OpenSSL Version: Support for OpenSSL 1.1.x was removed in version 47.0.0. OpenSSL 3.0.0 or later is now required.
• macOS Support: Support for x86_64 macOS was removed in version 49.0.0. Users on this architecture should move to a 64-bit Python installation.
• Algorithm Removals:
  • Support for binary elliptic curves (SECT* classes) was removed in 47.0.0.
  • Several deprecated ciphers and modes, including Camellia, CFB, OFB, and CFB8, were removed in 49.0.0.
• Stricter Validation:
  • ChaCha20 nonce handling is now stricter to prevent counter overflow, raising a ValueError for oversized data.
  • Loading X.509 CRLs and keys with unsupported or invalid parameters will now raise errors immediately instead of during validation.

Recommendation: Before merging, verify that your environment meets the new Python and OpenSSL version requirements. Audit your codebase for any usage of the removed algorithms and ciphers. Thorough testing is required to ensure compatibility with the stricter validation rules.
