12.30.1 (2026-08-24)
Bugs Fixed
- Fixed a bug where client-side encryption 2.0 could not detect a rearrangement of otherwise-untampered authenticated regions in blob content. This is now detected and exceptions are thrown. For data recovery purposes, this behavior can be reverted by setting the "AZURE_STORAGE_CSE_V2_ALLOW_MISORDERED_AUTH_REGIONS" environment variable.
- Fixed a bug in client-side encryption where version downgrades, and other metadata tampering, was only detected at the start of a download.
