### Acknowledgments
Thank you to our developer community members who helped to make the Event Hubs client libraries better with their contributions to this release:
- Christopher Scott _([GitHub](
- Roman Marusyk _([GitHub](
#### Consuming events
- The `EventProcessorClient` has been enhanced to derive from the new `EventProcessor<TPartition>` primitive, bringing improvements to stability, resilience, and performance.
#### Publishing events
- Event batches are now protected against modification while publishing is actively taking place.
#### Bug fixes and foundation
- Validation for the Event Hubs fully qualified namespace has been improved, allowing for more deterministic failures when creating clients.
- Exceptions surfaced will now properly remember their context in all scenarios; previously, some deferred cases unintentionally reset the context.
- Logging for the Storage Manager for Azure Blobs now follows the common pattern for other Event Hubs types, as well as providing additional context and information.
- The diagnostic scope for activities will now complete in a more deterministic manner.  (A community contribution, courtesy of [christothes]((
- Diagnostic activities have been extended with additional information about events being processed and with additional environmental context.
- Parsing of connection strings is now more permissive for the `Endpoint` key, allowing additional formats that result from common mistakes when building the string rather than copying the value from the portal.
- The partition manager has been renamed to `StorageManager` to better represent its purpose.  (A community contribution, courtesy of ([marusyk](
#### Testing
- The tests for load balancing and the Event Processor client have been tuned to remove dependencies on Azure resources and run more efficiently.  (A community contribution, courtesy of [christothes](
