1.8.1-beta.1 (2026-07-24)

Features Added

• Added support for Structured Message CRC64 content validation on upload and download operations using TransferValidationTypeComputeStructuredMessageCRC64.
• Added StorageResponseFormat enum (Auto, XML, Arrow) for list blobs operations. Set ResponseFormat on ListBlobsFlatOptions/ListBlobsHierarchyOptions to opt into Apache Arrow format for improved performance. Auto defaults to XML for this release.
• Added AccessTier, AccessTierInferred, AccessTierChangeTime, and SmartAccessTier fields to blob download response.
• Blob put operations now return both ContentMD5 and ContentCRC64 in the response when a Content-MD5 header is provided (service version 2026-10-06+).

Bugs Fixed

• Fixed UploadFile/UploadBuffer responses not including ContentCRC64 when returned by the service.

Other Changes

• Updated code generator to @autorest/go@4.0.0-preview.80.
• Default upload/download concurrency is now based on CPU core count (clamped between 8 and 96) instead of the fixed value of 5. Set AZURE_STORAGE_USE_LEGACY_DEFAULT_CONCURRENCY=true to revert to previous defaults.
• Updated azidentity version to 1.14.0
