v1.7.0

Breaking Changes

Structured logging removed from CLI commands

The CLI itself no longer uses structured logging. Warnings and errors are printed as plain text to stderr. The --log-level flag now only controls logging for the SDK client and server start-dev. Its default has changed from info to never for most commands (warn for server start-dev).

If you rely on structured log output, pass --log-level info explicitly to restore the previous SDK logging behavior.

Activity command flag changes

Removed flags: The --activity-type and --match-all flags have been removed from temporal activity pause, temporal activity unpause, temporal activity reset, and temporal activity update-options. These were experimental and allowed targeting all activities of a given type within a single workflow. They have been removed in favor of upcoming server-side batch operations that will be more intuitive. Use --activity-id with --workflow-id, or --query for batch targeting.

Changed flag semantics: --workflow-id is no longer always required for temporal activity complete and temporal activity fail. It is required for workflow-attached activities but must be omitted for Standalone Activities. When --workflow-id is absent, --run-id refers to the Activity Run ID rather than the Workflow Run ID. Existing scripts that always pass --workflow-id are unaffected.

New Features

Standalone Activity Support (Experimental)

New subcommands under temporal activity for managing Standalone Activities:

• temporal activity start -- Start a new Standalone Activity
• temporal activity execute -- Start a Standalone Activity and wait for its result
• temporal activity result -- Wait for and output the result of a Standalone Activity
• temporal activity describe -- Show detailed info for a Standalone Activity
• temporal activity list -- List Standalone Activities matching a query
• temporal activity count -- Count Standalone Activities matching a query
• temporal activity cancel -- Request cancellation of a Standalone Activity
• temporal activity terminate -- Forcefully end a Standalone Activity

The dev server (temporal server start-dev) automatically enables the required dynamic config flags (EnableChasm and activity.Enabled). For self-hosted server deployments, these must be enabled manually. They will be on by default starting in server v1.32.

Worker Deployment Commands

Added temporal worker deployment create and temporal worker deployment create-version commands for managing Worker Deployments via direct gRPC API calls, including AWS Lambda compute configuration.

Task Queue Fairness Weight Overrides

Added CLI support for setting fairness key weight overrides via UpdateTaskQueueConfig. This allows configuring per-key weights on task queues directly from the CLI.

Nexus Caller Timeouts

Pending Nexus operations now display ScheduleToStart and StartToClose timeouts in workflow output.

Reverse workflow history

List workflow history events in reverse (newest event first) using the new --reverse flag on temporal workflow show. Helpful for debugging workflows where you only care about the most recent events.

Improvements

• Experimental warning on activity batch operations -- Activity batch operations now display an experimental warning.

Bug Fixes

• --tls=false now correctly disables TLS when used with --api-key -- Previously, passing --api-key X --tls=false would still dial with TLS enabled because the SDK auto-enables TLS when credentials are present. The envconfig v1.0.0 upgrade fixes ToClientOptions to respect the explicit --tls=false flag. (sdk-go#2205)
• Task queue warnings go to stderr -- Warnings in task queue commands (e.g. the stop-all-queues confirmation) were incorrectly sent to stdout, breaking structured output. They now go to stderr. (#1000)
• --build-id and --unversioned mutual exclusivity enforced -- temporal worker deployment set-current-version now returns an error if both flags are provided. Previously the conflict was silently ignored. (#991)
• Activity command flag fixes (#974):
  • activity pause silently ignored the --identity flag, always sending the global client identity
  • activity pause was missing the --reason flag despite the server accepting one
  • --activity-type displayed activity-id as its value placeholder in help output for pause, unpause, and reset
  • --reset-heartbeats on unpause and reset incorrectly claimed it only works with --reset-attempts
  • activity complete and activity fail lacked the a shorthand for --activity-id that other activity subcommands had
• temporal env deprecation warning now visible at all log levels -- The warning about deprecated positional arguments was routed through the logger, so it was invisible at the new default --log-level never. It now prints directly to stderr.
