## Release highlights

[pattern]: # (### ${PackageFriendlyName} ${PackageVersion} [Changelog]${ChangelogUrl}`n${HighlightsBody}`n)
### Event Hubs 5.3.1 [Changelog](https://github.com/Azure/azure-sdk-for-python/blob/master/sdk/eventhub/azure-eventhub/CHANGELOG.md#531-2021-03-09)

This version will be the last version to officially support Python 3.5, future versions will require Python 2.7 or Python 3.6+.

#### Bug fixes

- Sending empty `event_data_batch` will be a no-op now instead of raising error.

### Event Hubs 5.4.0b1 [Changelog](https://github.com/Azure/azure-sdk-for-python/blob/feature/eventhub%2Fidempotent-producer/sdk/eventhub/azure-eventhub/CHANGELOG.md#540b1-2021-03-09)

This version and all future versions will require Python 2.7 or Python 3.6+, Python 3.5 is no longer supported.

#### New Features

- Added support for idempotent publishing which is supported by the service to endeavor to reduce the number of duplicate
events that are published.
- `EventHubProducerClient` constructor accepts two new parameters for idempotent publishing:
- `enable_idempotent_partitions`: A boolean value to tell the `EventHubProducerClient` whether to enable idempotency.
- `partition_config`: The set of configurations that can be specified to influence publishing behavior
specific to the configured Event Hub partition.
- Introduced a new method `get_partition_publishing_properties` on `EventHubProducerClient` to inspect the information
about the state of publishing for a partition.
- Introduced a new property `published_sequence_number` on `EventData` to get the publishing sequence number assigned
to the event at the time it was successfully published.
- Introduced a new property `starting_published_sequence_number` on `EventDataBatch` to get the publishing sequence
number assigned to the first event in the batch at the time the batch was successfully published.
- Introduced a new class `azure.eventhub.PartitionPublishingConfiguration` which is a set of configurations that can be
specified to influence the behavior when publishing directly to an Event Hub partition.

#### Notes

- Updated uAMQP dependency to 1.2.15.
