Highlights
SDK is now Beta
Ruby SDK is now in beta and will be GA soon. Being in beta means that APIs are fairly stable and there has been plenty of production usage to confirm the quality and approach. Although no exact timetable is set, it will not be too long before 1.0. Please use the SDK and give feedback to help us get to GA faster.
Workflow Replayer
Temporalio::Worker::WorkflowReplayer is now available to replay workflow histories. This is an important utility to be able to test that new workflow code is safe to run against existing histories. Using this with debug_mode=true is a common way to debug and step through past executions to see what exact lines of code were executed.
MUSL Support
Linux MUSL x64 gems are now published for each release. This allows users to use Alpine-based images/containers to run the SDK.
Update-with-Start and Signal-with-start
The client now supports signal_with_start_workflow, start_update_with_start_workflow, and execute_update_with_start_workflow. As of this writing, update with start is not yet GA, but it will be soon.
OpenTelemetry Tracing
Temporalio::Contrib::OpenTelemetry module is now present that contains a TracingInterceptor class that can be set on clients for enabling OpenTelemetry tracing, and a Workflow module with with_completed_span/completed_span helpers. See the README section on OpenTelemetry for more details.
