- Major improvements
- Replaced networking stack with the Bedrock layer of ASP.NET Core
- Support for future wire protocol versioning
- A series of improvements in cluster recovery from node failures
- Pluggable data adapters for EventHub stream provider
- Compatibility with .NET Core 3.0
This release is backward compatible, over the wire messaging wise, with 2.* releases, which allows for in-place upgrade of a running cluster. However, there are several breaking changes in the APIs that might require minor adjustments for application code to compile.
We measured significant performance gains with this release over 2.* versions, ranging from 8% to 93% depending on the test, mostly due to the network stack rewrite.
