Changes since 2.3.0-rc1.

Refactored stream batch behaviors to support batch consumption. (#5425) is the only change. While technically it is breaking due to the changes to the batch streaming API, it shouldn't break any working application code because the batching functionality wasn't fully wired previously. No breaking change in the wire protocol or persistence. This release is backward-compatible with 2.x releases.

• Major improvements

  • Support for the ASP.NET Core hosting API (Microsoft.Extensions.Hosting).
  • Replacement of the custom implementation of named options with Microsoft.Extensions.Options.
  • EventHub stream provider got upgrade to EvenHub 2.2.1 and is also compatible with 3.0.0.
  • Old dead entries in the cluster membership table now get automatically cleaned up, which is helpful for hosting environments that use new IP endpoints for restarted silos.
  • Hosted client that enables efficient hosting of frontend code within the silo process is now enabled by default.

This release includes a number of performance improvements, the biggest one being the new scheduler, that all add up in our tests to up to 30% throughput increase on the same hardware.

It also brings the support for distributed transaction to what we consider "release candidate" quality, with the new Distributed Transaction Manager at its core. We plan to declare transactions production ready in a subsequent release, after another round of testing and improvements.

Lastly, this release includes a new code generation package Microsoft.Orleans.CodeGenerator.MSBuild that can be used as an alternative to Microsoft.Orleans.OrleansCodeGenerator.Build. The new code generator leverages Roslyn Code Analysis functionality to avoid loading application binaries. As a result, it avoid issues caused by clashing dependency versions and multiple versions of the .NET Core SDK.

This release includes no breaking changes and is backward compatible with 2.0.* releases, which allows for in-place upgrade of a running cluster.

Warning: If you are using Orleans with .NET Core 2.1, do not enable TieredCompilation for Orleans silo and client projects. We recently discovered a CLR bug that is breaking Orleans when TieredCompilation is enabled. See #4990 for more details.
