Highlights
Temporal Ruby SDK Generally Available
With this 1.0.0 release, the Ruby SDK is now considered stable. This means it has been thoroughly used and tested to ensure it meets Temporal quality standards. Throughout the prerelease period, we have received ample feedback and have adjusted the SDK as needed to address feedback and address any issues encountered. We strive to not make any backwards incompatible changes.
Environment Configuration Support (experimental)
Users can now use Temporalio::EnvConfig to load environment configuration from config files or environment variables. This is the same configuration approach that can be used across other SDKs and CLI. See https://docs.temporal.io/develop/environment-configuration for more details.
Custom Slot Suppliers (experimental)
Worker tuners can now provide custom slot suppliers. This is for very advanced use cases that need custom logic to determine when a slot can be reserved. A custom implementation of Temporalio::Worker::Tuner::SlotSupplier::Custom can be provided for slot suppliers in a tuner which is then called from the C extension to determine if a slot can be reserved and to report on usage/release of the slot. Users of this API should pay close attention to API docs since it can affect the running of the system if implemented improperly.
