1.17.0

Notable Changes

Added

• Added experimental AWS Lambda worker support packages, including OpenTelemetry helpers for Lambda workers.
• Added experimental workflow-side Workflow.SignalWithStartWorkflowAsync support.

Changed

• Changed the default TemporalConnectionOptions.GrpcCompression to GrpcCompression.Gzip, so
  connections now compress outbound requests and accept gzip-compressed responses by default. If the remote
  service does not support gzip compression, the connection is downgraded to uncompressed requests. Set it
  to GrpcCompression.None to opt out.

Fixed

• Fixed ClientEnvConfig empty OverrideEnvVars handling so an explicit empty dictionary no
  longer falls back to process environment variables.
• Fixed ClientEnvConfig TLS-disabled profiles to preserve disabled TLS in connection options.
• OTLP metric export failures are now logged through Core telemetry when OpenTelemetry's periodic metric reader reports an export error.
• Worker heartbeat now samples host CPU/memory at the heartbeat interval (only when enabled) rather than every 100ms.
