 * **BACKWARDS INCOMPATIBLE:** Support for OpenSSL less than 1.1.1e has been
   removed.  Users on older version of OpenSSL will need to upgrade.
 * **BACKWARDS INCOMPATIBLE:** Dropped support for LibreSSL < 3.8.
+* Updated the minimum supported Rust version (MSRV) to 1.65.0, from 1.63.0.
 * :func:`~cryptography.hazmat.primitives.asymmetric.rsa.generate_private_key`
   now enforces a minimum RSA key size of 1024-bit. Note that 1024-bit is still
   considered insecure, users should generally use a key size of 2048-bits.
