This is a massive upgrade, jumping from version 2.9.2 (released in 2020) to 48.0.1 (released in 2026). It includes a very long list of breaking changes that will require significant code and environment updates.

Key Breaking Changes:

• Python Version: Support for Python versions older than 3.9 has been completely removed. The original version 2.9.2 supported Python 2.7 and 3.5+.
• OpenSSL Dependency: The required OpenSSL version has been significantly updated. Support for OpenSSL 1.1.1 was removed in cryptography v42.0.0. The wheels for v48.0.1 are compiled with OpenSSL 4.0.1. Systems using older system-provided OpenSSL versions will need to be updated or use the statically linked wheels.
• API Removals and Redesigns: Over the course of dozens of major versions, countless APIs have been removed, renamed, or redesigned. This includes:
  • Removal of support for binary elliptic curves (SECT*).
  • Removal of many insecure and outdated algorithms, which have been moved to a decrepit module and are no longer available by default.
  • Significant changes to X.509 certificate handling and other low-level interfaces.
• Build System: The package now requires a Rust compiler for source builds, as some performance-critical components have been rewritten in Rust.

Source: Cryptography Changelog

Recommendation: This upgrade cannot be handled as a simple version bump. It requires a dedicated migration effort. Developers must carefully review the entire changelog, audit all usage of the cryptography library in the codebase, and perform extensive testing. Expect to rewrite significant portions of the code that interact with this library.
