This release is primarily about bringing support for ACID cross-grain transactions to production-ready quality. Other improvements and fixes are listed below.
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.
