Signal and Signal-with-start calls from Nexus operation handlers now propagate links for mutual UI navigation between caller and callee workflows, and standalone Nexus operation links are supported. Standalone activities now receive tracing spans through the OTel interceptor. Fixed SDK flags being ignored when GetSystemInfo lacks metadata support and RPC retry failures with gzip-unsupported servers.
SDKFlagBlockedSelectorSignalReceive and SDKFlagWorkflowNewChannelLostMessages are now enabled by default for new workflow executions. These flags previously gated fixes for selector/signal receive behavior…
When the namespace supports worker poll completion on shutdown, workers now notify the server during shutdown and allow already-polled Workflow, Activity, and Nexus tasks to finish…
NOTE: Stand Alone Nexus Operation Support is experimental and currently only supported on pre-release versions of the [[dev…
This patch fixes a panic that users hit when using the latest go.temporal.io/api v1.62.12 dependency with Go SDK v1.43.0
Within workers, if a payload exceeds the server limits, the worker will eagerly fail the current task instead of uploading the object with the too large payload or memo. This allows the task to be retried…
The minimum Go version for the Go SDK has been updated 1.24.0 due to required dependency updates having this Go version.
Fixed a permanent NDE on replay when Data Converter or Codec fails on Session activity cancellation. Refer to https://github.com/temporalio/sdk-go/pull/2228 for more details.
Also fixed an issue with worker heartbeat ctx not being propagated for cancellation on…
This release adds a new feature called Worker Heartbeating. This feature spins up a single nexus-only worker per Client/Namespace in the background and periodically sends some basic metrics over to server for all of the…
Due to Standalone Activities, testActivityToken are used to keep track of activities, instead of just activityID, they now contain activityID and runID. Most users should not be affected, only if you're manually constructing task tokens in your…
