Release Kalix Java/Scala SDKs

Prepare

• Make sure all important PRs have been merged
• Check that the latest build successfully finished
• Make sure a version of the Kalix Runtime that supports the protocol version the SDK expects has been deployed to production

You can see the Kalix Runtime version on prod on grafana or using various other methods.

Cutting the release

• Update the "Change date" on the license to release date plus three years and the version of the SDK in "Licensed Work".
• Use the "Generate release notes" button to create a new release with the appropriate tag.
  • Review the generated notes and "Publish release"
  • CI will automatically publish to the repository based on the tag

Check availability

• Manually update docs/kalix-current (There is a workflow but that has been failing, possibly for expired secrets)

  • To update that branch, run this locally

    git fetch --tags
    cd docs
    make deploy

• Check the released artifacts

  • Check the parent pom version is available at maven central https://repo1.maven.org/maven2/io/kalix/kalix-java-sdk-protobuf-parent/
  • Check the version is listed in our own https://repo.akka.io/maven/io/kalix/kalix-jvm-core-sdk/.

Fix and publish docs

• In case there were important updates, update the supported version in the main docs (affects Supported Languages)
• Add an item to the Release Notes in the documentation
• Release the Kalix documentation to get the SDK docs updates published

Update to the latest version

• Review and merge PR created by bot (should appear here). While reviewing confirm the release version is updated for:
  • kalix-sdk.version in the samples/*/pom.xml files
  • kalix-sdk.version default value in the samples/scala-*/project/plugins.sbt files
  • version in maven-java/**/pom.xml

Check docs update

• Check for updated docs (see the timestamp on the bottom of the page) - no longer there
• Check for the latest version on the dependency configuration example

Announcements

• Add a summary of relevant changes and a link to the release notes into Kalix Release Notes aggregation
• Close this issue
