Matthias Pohl created FLINK-31153:
-------------------------------------
Summary: Create a release branch
Key: FLINK-31153
URL: https://issues.apache.org/jira/browse/FLINK-31153
Project: Flink
Issue Type: Sub-task
Reporter: Matthias Pohl
If you are doing a new major release, you need to update Flink version in two
repositories:
* [apache/flink|https://github.com/apache/flink]
* [apache/flink-docker|https://github.com/apache/flink-docker]
* [apache/flink-benchmarks|https://github.com/apache/flink-benchmarks]
h4. Flink repository
Create a branch for the new version that we want to release before updating the
master branch to the next development version:
{code:bash}
$ cd ./tools
$ releasing/create_snapshot_branch.sh
$ git checkout master
$ OLD_VERSION=$CURRENT_SNAPSHOT_VERSION NEW_VERSION=$NEXT_SNAPSHOT_VERSION
releasing/update_branch_version.sh
{code}
In the {{master}} branch, add a new value (e.g. {{v1_16("1.16")}}) to
[apache-flink:flink-annotations/src/main/java/org/apache/flink/FlinkVersion|https://github.com/apache/flink/blob/master/flink-annotations/src/main/java/org/apache/flink/FlinkVersion.java]
as the last entry:
{code:java}
// ...
v1_12("1.12"),
v1_13("1.13"),
v1_14("1.14"),
v1_15("1.15"),
v1_16("1.16");
{code}
The newly created branch and updated {{master}} branch need to be pushed to the
official repository.
h4. Flink Docker Repository
Afterwards fork off from {{dev-master}} a {{dev-x.y}} branch in the
[apache/flink-docker|https://github.com/apache/flink-docker] repository. Make
sure that
[apache/flink-docker:.github/workflows/ci.yml|https://github.com/apache/flink-docker/blob/dev-master/.github/workflows/ci.yml]
points to the correct snapshot version; for {{dev-x.y}} it should point to
{[x.y-SNAPSHOT}}, while for {{dev-master}} it should point to the most recent
snapshot version ({[$NEXT_SNAPSHOT_VERSION}}).
After pushing the new major release branch, as the last step you should also
update the documentation workflow to also build the documentation for the new
release branch. Check [Managing
Documentation|https://cwiki.apache.org/confluence/display/FLINK/Managing+Documentation]
on details on how to do that. You may also want to manually trigger a build to
make the changes visible as soon as possible.
