new-actions bug-fix description-fixAdded the append_block action, which writes content to the end of an append blob (Azure’s Append Block operation). Previously upload_blob could create an empty append blob but nothing could write bytes into it, so append-style log workflows could not complete; append_block closes that gap and can be called repeatedly to grow a log. upload_blob’s description now points to append_block for writing append-blob content. Description hardening — copy_blob now explicitly requires reading the account blob endpoint (ServiceEndpoint) from list_containers and forbids guessing the host, which otherwise returns 409 CannotVerifyCopySource.

bug-fix description-fixBehavioural bug-fixes from agent testing — upload_blob now sends the raw file bytes (switched from multipart/form-data to a binary body) so stored content is byte-faithful and Append/Page blobs create correctly (file_content is now optional for empty page/append creation); create_blob_snapshot now returns the x-ms-snapshot id (plus etag, lastModified, versionId) so the new snapshot is addressable. Description clarifications — copy_blob documents the same-account copySource URL format and the ServiceEndpoint from list_containers, undelete_blob notes it does not promote the base version on versioning-enabled accounts, list_blobs notes the permissions include is HNS-only, and create_container / set_container_acl / upload_blob expiryOption / abort_copy_blob document their storage-account requirements (public access, hierarchical namespace, asynchronous copy).

documentationSetup guide improvements from documentation audit — Entra ID app-registration steps reordered so all Entra portal work is contiguous (client secret before RBAC), single-tenant account-type wording covers both portal label forms, added old-UI “Add a platform” fallback for the redirect URI step, noted offline_access is requested automatically, added storage-account discovery navigation and “Job function roles” hint to the RBAC step, added “Storage center | Blob Storage” landing note, and clarified the accountName field description in the connection form.

native-webhooksAdded inbound webhook event support via Azure Event Grid (Manual setup) — 10 events (Blob Created, Blob Deleted, Blob Tier Changed, Async Operation Initiated, Data Lake Gen2 Blob Renamed and Directory Created/Renamed/Deleted, plus Blob Inventory Policy Completed and Lifecycle Policy Completed), with the SubscriptionValidation handshake handled automatically and a per-connection native webhook URL for scoping subscriptions to a storage account.
