3.217.0

Added

• Add support for Redis Pub/Sub.
• Add support for redis with location: remote.
• Added support for splitting Temporal task queues.
• Added the number of concurrent Preview Environment session to the output of
  mirrord operator status.
• The --key argument for mirrord exec, mirrord preview, and mirrord up
  can now be provided with the MIRRORD_KEY environment variable.

Changed

• A new command argument --resolved is added to the mirrord verify-config
  subcommand
  to display a fully resolved mirrord config including user inputs and all
  default
  values being used.
• Renamed the mirrord UI identity label to "Running as" (previously "Signed in
  as") to reflect that it shows the active cluster identity queried by the CLI
  rather than an authenticated session.
• feature.network.dns.filter is no longer marked as unstable in config docs
  or CLI warnings.

Fixed

• Fixed concurrent DNS resolution intermittently failing under mirrord on
  Windows. A burst of in-flight async GetAddrInfoExW queries, such as a .NET
  HttpClient issues under load, could exhaust the managed-handle registry's
  single-lock retry budget and drop a query, which surfaced to the app as a
  WSAHOST_NOT_FOUND SocketException. The registry now shards its lock
  across independent shards, so concurrent registration no longer serializes on
  one lock.
• Fixed concurrent file I/O contending the Windows IOCP file-binding map
  under mirrord. Many parallel open/close operations serialized on a single
  RwLock, so bind and unbind could give up under contention and drop a
  file's async-read completion binding, or leak its entry on close. The binding
  now lives in the file's managed-handle record, which shards its lock across
  independent locks and drops the binding atomically when the handle closes.
• Preview environments now hash the session key before placing it in the
  PreviewSession resource's label. In practice this means keys containing
  characters like /, which are invalid for Kubernetes labels, are accepted.
