v1.6.0

Highlights

• This release contains important fixes that improve the stability of workers.
• Numerous fixes for worker thread leaks and handling of failure cases.
• There is a race condition in gRPC-java that may break workers. This release contains a workaround until the issue is fixed.

Migration notes

temporal-testing-junit4, temporal-testing-junit5, and temporal-testing merged into one temporal-testing module that exposes Gradle "capabilities."
For Gradle:
See https://github.com/temporalio/sdk-java/tree/master/temporal-testing#usage for Gradle-specific instructions. Or you can just switch to temporal-testing and provide junit dependency yourself without digging into Gradle's capabilities.
For other build tools:
Just switch onto using just temporal-testing instead of temporal-testing-junit4 or temporal-testing-junit5.
