Now, add your Apache GPG key to the Flink’s KEYS
file in the release
repository at dist.apache.org
. Follow the instructions listed at the top of these files. (Note: Only PMC members have write access to the release repository. If you end up getting 403 errors ask on the mailing list for assistance.)Configure git
to use this key when signing code by giving it your key ID, as follows: PMC member can refer following scripts to add your Apache GPG key to the KEYS in the release repository.

git config --global user.signingkey 845E6689 |
You may drop the --global
option if you’d prefer to use this key for the current repository only.
You may wish to start gpg-agent
to unlock your GPG key only once using your passphrase. Otherwise, you may need to enter this passphrase hundreds of times. The setup for gpg-agent
varies based on operating system, but may be something like this:

eval $(gpg-agent --daemon --no-grab --write-env-file $HOME/.gpg-agent-info)

Website development setup
Get ready for updating the Flink website by following the website development instructions.
Create a new version in JIRA
When contributors resolve an issue in JIRA, they are tagging it with a release that will contain their changes. With the release currently underway, new issues should be resolved against a subsequent future release. Therefore, you should create a release item for this subsequent release, as follows:
- In JIRA, navigate to the Flink
> Administration > Versions
. - Add a new release: choose the next minor version number compared to the one currently underway, select today’s date as the
Start Date
, and chooseAdd
.
Triage release-blocking issues in JIRA
There could be outstanding release-blocking issues, which should be triaged before proceeding to build a release candidate. We track them by assigning a specific Fix version
field even before the issue resolved.
The list of release-blocking issues is available at the version status page. Triage each unresolved issue with one of the following resolutions:
- If the issue has been resolved and JIRA was not updated, resolve it accordingly.
- If the issue has not been resolved and it is acceptable to defer this until the next release, update the
Fix Version
field to the new version you just created. Please consider discussing this with stakeholders and the dev@ mailing list, as appropriate. - If the issue has not been resolved and it is not acceptable to release until it is fixed, the release cannot proceed. Instead, work with the Flink community to resolve the issue.
Review Release Notes in JIRA
JIRA automatically generates Release Notes based on the Fix Version
field applied to issues. Release Notes are intended fo users (not Flink committers/contributors). You

- Dev repository https://dist.apache.org/repos/dist/dev/flink/ is empty
- Release tagged in the source code repository
- Release version finalized in JIRA. (Note: Not all committers have administrator access to JIRA. If you end up getting permissions errors ask on the mailing list for assistance)
- Website contains links to new release binaries and sources in download page
- For major releases, the front page references the correct new major release version and directs to the correct link
- Dockerfiles in flink-statefun-docker updated for the new release and pull request opened on the Docker official-images with an updated manifestthe new images have been pushed to Dockerhub
- flink-statefun-playground contains a new release branch with updated versions (if major/minor release)
Promote the release
Once the release has been finalized, the last step of the process is to promote the release within the project and beyond. Please wait for 24h after finalizing the release in accordance with the ASF release policy.
