Release Highlights

v0.27.0 maintains Temporal's "Alpha" release state.
Do not use this release for production workloads as there are breaking changes planned for future releases.

This release includes:

• Import path renames
• Major entity renames
• tctl improvements
• Other minor updates

Change details

Import path renames

1. go.temporal.io/temporal-proto → go.temporal.io/api
2. go.temporal.io/temporal → go.temporal.io/sdk: Root files were moved to temporal directory, so package name remained the same but import path changed from go.temporal.io/temporal to go.temporal.io/sdk/temporal.
3. github.com/temporalio/temporal → go.temporal.io/server
4. github.com/temporalio/temporal/.gen/proto→ go.temporal.io/server/api: This is already checked into the repo. This enables the reference of the server package to build a custom version.

Major entities renames:

1. RetryStatus → RetryState
2. ArchivalStatus → ArchivalState
3. NamespaceStatus → NamespaceState: Note that, in the config file, status: needs to be renamed to state:.
4. DecisionTask → WorkflowTask
5. Decision → Command
6. Decider → Workflow

Things we are still working on

1. We are still working and cleaning some internal API contracts. So more breaking changes are coming. So please don't use this for production setup yet.
2. Stress and Performance testing.
