- Major improvements
- Support for the ASP.NET Core hosting API (Microsoft.Extensions.Hosting). Thanks to @galvesribeiro!
- 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.
- Support for
IHostEnvironmentStatisticson Linux, which enables CPU and memory metrics as well as load shedding. Thanks to @martinothamar!
This release is backward compatible with 2.0.* releases, which allows for in-place upgrade of a running cluster.
Three new NuGet packages were added:
-
Breaking changes
- No changes breaking the wire protocol or persisted state that would break a rolling upgrade
- Migration to Microsoft.Extensions.Options 2.1.1 (#5385) requires a namespace change in the code
Refactored stream batch behaviors to support batch consumption.(#5425) technically a breaking change due to the changes to the batch streaming API. However, it shouldn't break any working application code because the batching functionality wasn't fully wired previously.
This release is backward-compatible with 2.x releases.
