Changelog

Detailed change logs are linked to in the Quick Links below. Here are some critical call outs.

Azure Identity

  • Added new user credential types, allowing authentication within client applications.

Event Hubs

  • Expanded support for sending multiple messages in a single call by adding the ability to create a batch which avoids the error scenario of exceeding size limits. Users having bandwidth concerns can control the batch size as desired.
  • Introduced a new model for consuming events via the EventProcessor class. This simplifies the process of checkpointing today and will handle load balancing across partitions in upcoming updates.

Key Vault

  • Added support for cryptographic operations (such as sign, verify, encrypt, and decrypt) using KeyVault keys.
  • Added support for challenge based authentication.

Storage

  • Added async API support for all supported storage types (blobs, files, and queues).
