Release Notes

Azure/azure-sdk-for-net (Azure.Storage.Blobs)

v12.29.2

Compare Source

12.29.2 (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 enabling "Azure.Storage.CseV2AllowMisorderedAuthRegions" in the AppContext switch or "AZURE_STORAGE_CSE_V2_ALLOW_MISORDERED_AUTH_REGIONS" in environment variables.
• Fixed a bug in client-side encryption where version downgrades were only detected at the start of a download.

v12.29.1

Compare Source

12.29.1 (2026-06-23)

Bugs Fixed

• Fixed an issue where the GenerateSasUri and GenerateUserDelegationSasUri convenience methods on blob clients did not honor the RequestHeaders and RequestQueryParameters properties, and where GenerateUserDelegationSasUri did not honor DelegatedUserObjectId, set on the supplied BlobSasBuilder.
• Fixed an issue where structured-message Uploads with checksum validation could fail with a ArgumentOutOfRangeException for empty content
