UPDATE: Due to #740 bug docker-compose version of the server can't be started more than once. Please use v0.31.0 instead.

Release Highlights

v0.30.0 maintains Temporal's "Alpha" release state. Please do not use this release for production workloads.

Important

1. You can not rollback to a previous version once you have upgraded to v0.30.0. Data that is created in v0.30.0 is not supported by older versions and you will get panic: runtime error: invalid memory address or nil pointer dereference when the service tries to start. Using an older version after the upgrade will require a fresh install.

2. After upgrading to v0.30.0 you can not call Reset on Workflows which were started with a previous version. However, you can still call Reset on Workflows that were started while running v0.30.0.
