# Apache Beam Release Guide
## Introduction
The Beam community treats releases with great importance. They are a public
face of the project and most users interact with the project only through the
releases. Releases are signed off by the entire Beam community in a public
vote.
Each release is executed by a *Release Manager*, who is selected among the Beam
committers. This document describes the process that the Release Manager
follows to perform a release.
Please remember that publishing software has legal consequences. This guide
complements the foundation-wide guides:
- [Product Release Policy](https://www.apache.org/dev/release.html)
- [Release Distribution
Policy](https://www.apache.org/dev/release-distribution).
### What is in a Beam release
A Beam release consists of the following:
- ASF source zips archived on
[dist.apache.org](https://dist.apache.org/release/beam) (later archived to
[archive.apache.org](https://archive.apache.org/dist/beam)
- Java jars and poms published to [Maven
Central](https://mvnrepository.com/artifact/org.apache.beam)
- Python wheels published to [pypi](https://pypi.org/project/apache-beam/)
- Go artifacts published to
[pkg.go.dev](https://pkg.go.dev/github.com/apache/beam)
- Docker images published to
[dockerhub](https://hub.docker.com/search?q=apache%2Fbeam&type=image)
- A tag on GitHub indicating the commit from which the release was built
In addition, each release is accompanied by:
- A blog post announcing the release and describing the changes
- An update to the webpage to indicate the latest version
### Phases of the release process
The release process consists of several phases:
1. Prepare for release
2. Stabilize the release branch / burn down release-blocking issues
3. Build a release candidate
4. Validate and approve the release candidate
5. Finalize the release
6. Promote the release
7. Post-release tasks
------------
## Prepare for release (~1 week before release cut)
The following steps take place before the release branch is cut.
### Decide to release
Deciding to release and selecting a Release Manager is the first step of the
release process. This is a consensus-based decision of the entire community.
Anybody can propose a release on the `dev@` list. There is no formal process,
no vote requirements, and no timing requirements. A committer must be
identified to be the Release Manager. In practice, most often a committer both
proposes to release and volunteers themselves as Release Manager.
-------
### Create a new milestone in GitHub for the next release
When contributors resolve an issue in GitHub, 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 GitHub, navigate to [`Issues > Milestones > New
Milestone`](https://github.com/apache/beam/milestones) and add a new
release for the next minor version after the version you are preparing
to release.
----
### Prepare accounts, keys, etc
Before your first release, you need to make sure you have all the necessary
accounts, keys, and access for publishing the release. The release process also
requires a variety of API tokens, which you can generate now or later when they
are needed.
These are the credentials you will need:
- Apache ID and Password
- GitHub ID, Password, and Personal Access Token
- PyPi account with beam maintainer access and API Token
- GPG pass phrase & 16-digit key ID
- Access to Beam's Apache Nexus repository
- Account to access to apache-beam-testing Google Cloud Platform project. The
account must have permissions to start Cloud Build triggers. Required for
Playground environment update. (E-mail at dev@ mailing list to request
access)
#### Apache ID and Password
This is your Apache committer user name and password. You selected these when
you became an Apache Beam Committer.
#### Github ID, Password, and Personal Access Token
- [ ] If you are using [GitHub two-factor
authentication](https://help.github.com/articles/securing-your-account-with-two-factor-authentication-2fa/)
and haven't configure HTTPS access, please follow [the
guide](https://help.github.com/articles/creating-a-personal-access-token-for-the-command-line/)
to configure command line access.
- [ ] Generate a Personal Access Token with `repo` and `workflow` permissions.
They can be generated from this page: https://github.com/settings/tokens.
See
https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens
for details.
#### PyPI account and API token
- [ ] [Create an account with PyPI](https://pypi.python.org/account/register/)
if you don't have one already.
- [ ] Become a maintainer (or an owner) of the
[apache-beam](https://pypi.python.org/pypi/apache-beam) package.
- [ ] Generate a [PyPI APIToken](https://pypi.org/help/#apitoken) for use
during the release.
#### GPG Key
You need to have a GPG key to sign the release artifacts. Please be aware of
the ASF-wide [release signing
guidelines](https://www.apache.org/dev/release-signing.html). If you don’t
have a GPG key associated with your Apache account, you must now create one
according to the guidelines.
Run the following helper script, or you can open it and run the commands
individually (helpful if it doesn't work as intended or if you already are
partially set up)
./release/src/main/scripts/preparation_before_release.sh
> **__NOTE__**:
> When generating the key, please make sure you choose the key type as
> __RSA and RSA (default)__ and key size as __4096 bit__.
Now you should have:
- [ ] A GPG key meeting ASF guidelines
- [ ] The key added to
[dev KEYS](https://dist.apache.org/repos/dist/dev/beam/KEYS) and [release KEYS](https://dist.apache.org/repos/dist/release/beam/KEYS)
**NOTE**: Only PMC can write into [release repo](https://dist.apache.org/repos/dist/release/beam/).
- [ ] The `user.signingkey` set in your `.gitconfig`
- [ ] `gpg-agent` with the key loaded
##### Key ID
You may need your Key ID for future steps. Determine your Apache GPG Key and
Key ID as follows:
gpg --list-sigs --keyid-format LONG
This will list your GPG keys. One of these should reflect your Apache account,
for example:
--------------------------------------------------
pub rsa4096/845E6689845E6689 2016-02-23
uid Nomen Nescio <anonymous@apache.org>
sub rsa4096/BA4D50BEBA4D50BE 2016-02-23
Here, the key ID is the 16-digit hex string in the `pub` line: `845E6689845E6689`.
##### Submit your GPG public key into Ubuntu OpenPGP Key Server
In order to make yourself have right permission to stage java artifacts in
Apache Nexus staging repository, please submit your GPG public key into the
[Ubuntu OpenPGP Key Server](https://keyserver.ubuntu.com/).
You will need to use an ascii-armored version of your key. This can be
obtained by running:
gpg --export --armor
Copying the whole block including `-----START PGP PUBLIC KEY BLOCK-----` and
`-----END PGP PUBLIC KEY BLOCK-----`
#### Access to Apache Nexus repository
Configure access to the [Apache Nexus
repository](https://repository.apache.org/), which enables final deployment of
releases to the Maven Central Repository.
1. Log in with your Apache account.
2. Confirm you have appropriate access by finding `org.apache.beam` under
`Staging Profiles`.
3. Navigate to your `Profile` (top right dropdown menu of the page).
4. Choose `User Token` from the dropdown, then click `Access User Token`. Copy
a snippet of the Maven XML configuration block.
5. Insert this snippet
twice into your global Maven `settings.xml` file, typically
`${HOME}/.m2/settings.xml`. The end result should look like this, where
`TOKEN_NAME` and `TOKEN_PASSWORD` are your secret tokens:
<!-- make sure you have the root `settings node: -->
<settings>
<servers>
<server>
<id>apache.releases.https</id>
<username>TOKEN_NAME</username>
<password>TOKEN_PASSWORD</password>
</server>
<server>
<id>apache.snapshots.https</id>
<username>TOKEN_NAME</username>
<password>TOKEN_PASSWORD</password>
</server>
</servers>
</settings>
----
### Dependency checks
Each language has routine dependency maintenance that you should check now.
#### Update base image dependencies for Python container images
The Python base container images have pinned `requirements.txt` that are
compatible with our dependency constraints, and design to avoid run-time
installs, since run-time installs cause large delays at start-up time. Ideally,
we this should happen regularly when dependencies update, but it is important
to ensure that they are fully up to date for each release.
Follow the instructions at
https://s.apache.org/beam-python-requirements-generate
#### Update Go version used for container builds
Go makes security patch releases of their tooling. This potentially affects
container bootloader security, and at the least can cause false positives when
an default-configuration scanner is pointed at our containers. Ideally, we
upgrade as soon as possible, but it is also good to ensure we are up to date
for each release.
See if https://go.dev/doc/devel/release has a newer release. Update throughout
Beam. See example at https://github.com/apache/beam/pull/27900/files
### Cut the release branch
> **Note**
> Wait until the proposed branch cut day!
We cut the release branch on time and do not block/delay branch cut for incoming
fixes. This is because bugs are always being introduced as part of normal
development. We cut the branch to prevent new bugs being introduced and _then_
we fix and cherrypick any truly release-blocking problems.
In order to run this workflow, you will need to provide a Apache ID and Jenkins
API token. Your Jenkins API token can be generated by visiting
https://ci-beam.apache.org, signing in with your Apache credentials, then going
to `https://ci-beam.apache.org/user/<your username>/configure` and clicking
`Add new token` in the API token section.
- [ ] Run
[cut_release_branch](https://github.com/apache/beam/actions/workflows/cut_release_branch.yml)
(click `run workflow`)
The final state of the repository after release branch is cut should match this
diagram:
<img src="images/cut-release-branch.png" alt="Increment minor version on master branch and set Dataflow container version on release branch" width="100%">
This should be accomplished by the
[cut_release_branch](https://github.com/apache/beam/actions/workflows/cut_release_branch.yml)
workflow.
The following must be manually done or confirmed:
- [ ] The `master` branch has the SNAPSHOT/dev version incremented.
- [ ] The release branch has the SNAPSHOT/dev version to be released.
- [ ] The Dataflow container image should be modified to the version to be released.
- [ ] Due to current limitation in the workflow, you must navigate to https://github.com/apache/beam/actions/workflows/beam_Release_NightlySnapshot.yml and click "Run workflow" and select the branch just created (release-2.xx.0) to build a snapshot.
- [ ] Manually update `CHANGES.md` on `master` by adding a new section for the
next release
([example](https://github.com/apache/beam/commit/96ab1fb3fe07acf7f7dc9d8c829ae36890d1535c)).
#### Inform the mailing list
The dev@ mailing list should be informed about the release branch being cut.
Alongside with this note, a list of pending issues and to-be-triaged issues
should be included. Afterwards, this list can be refined and updated by the
release manager and the Beam community.
### Checklist to proceed to the next phase
- [ ] Community agrees to release
- [ ] Community selects a committer (you) as Release Manager
- [ ] Next release has a milestone in github.
- [ ] You have your various account credentials prepared.
- [ ] You checked the dependency maintenance for each language.
- [ ] The release branch is created.
- [ ] The `master` branch is moved along to the next release.
- [ ] You have informed `dev@beam.apache.org` that you have cut the branch and
are proceeding to stabilization
-------
## Stabilize the release branch
Once the release branch is cut, your job is to make sure tests pass, fix bugs,
confirm performance, defer feature requests, etc, until the branch is ready for
the work of building a release candidate.
### Verify release branch
After the release branch is cut, make sure it builds and has no significant
issues that would block the creation of the release candidate.
> **NOTE**
> Dataflow tests will fail if the Dataflow worker container is not created and
> published by this time. Should be done by Google, in response to the
> creation of the release branch, and docker images are hosted. This should
> not block creation of the first release candidate, but should block approval
> of the release.
- **Script:**
[verify_release_build.sh](https://github.com/apache/beam/blob/master/release/src/main/scripts/verify_release_build.sh)
- **Usage**
1. Create a personal access token from your Github account.
See instruction [here](https://help.github.com/en/articles/creating-a-personal-access-token-for-the-command-line).
It'll be used by the script for accessing Github API.
You need to enable `repo` and `workflow` permissions for this token.
2. Update required configurations listed in `RELEASE_BUILD_CONFIGS` in [script.config](https://github.com/apache/beam/blob/master/release/src/main/scripts/script.config)
3. Then run
```
(cd release/src/main/scripts && ./verify_release_build.sh)
```
4. Trigger all Github Action and Jenkins PostCommit jobs from the PR created by the previous step.
For GitHub Action jobs, they should be triggered by the pull_request_target event of a specific placeholder file
added to the PR (`release/trigger_all_tests.json`), so no additional action should be needed.
You can run [mass_comment.py](https://github.com/apache/beam/blob/master/release/src/main/scripts/mass_comment.py) to do that.
Or manually add one trigger phrase per PR comment for Jenkins tests, or rerun the workflow for GitHub Action tests.
See [jenkins_jobs.txt](https://github.com/apache/beam/blob/master/release/src/main/scripts/jenkins_jobs.txt)
for a full list of phrases.
- **Tasks included in the script**
- Installs `hub` with your agreement and setup local git repo;
- Create a test PR against release branch;
There are some projects that don't produce the artifacts, e.g.
`beam-test-tools`, you may be able to ignore failures there.
To triage the failures and narrow things down you may want to look at
`settings.gradle.kts` and run the build only for the projects you're interested
at the moment, e.g. `./gradlew :runners:java-fn-execution`.
The `verify_release_build.sh` script may include failing or flaky tests. For
each of the failing tests create a GitHub Issue with the following properties:
* **Issue Type:** Bug
* **Summary:** Name of failing gradle task and name of failing test (where applicable) in form of :MyGradleProject:SomeGradleTask NameOfFailedTest: Short description of failure
* **Priority:** P1
* **Component:** "test-failures"
* **Milestone:** Release number of verified release branch
* **Description:** Description of failure
### Investigate performance regressions
Check the Beam load tests for possible performance regressions. Measurements
are available on [metrics.beam.apache.org](http://metrics.beam.apache.org).
All Runners which publish data should be checked for the following, in both
*batch* and *streaming* mode:
- [ParDo](http://metrics.beam.apache.org/d/MOi-kf3Zk/pardo-load-tests) and
[GBK](http://metrics.beam.apache.org/d/UYZ-oJ3Zk/gbk-load-test): Runtime,
latency, checkpoint duration
- [Nexmark](http://metrics.beam.apache.org/d/ahudA_zGz/nexmark): Query runtime
for all queries
- [IO](http://metrics.beam.apache.org/d/bnlHKP3Wz/java-io-it-tests-dataflow): Runtime
If regressions are found, the release branch can still be created, but the
regressions should be investigated and fixed as part of the release process.
The role of the release manager is to file GitHub issues for each regression
with the milestone set to the to-be-released version. The release manager
oversees these just like any other issue marked with the milestone of the
release.
The mailing list should be informed to allow fixing the regressions in the
course of the release. Issues should be filed and tagged with the milestone.
### Triage release-blocking issues in GitHub
There could be outstanding release-blocking issues, which should be triaged
before proceeding to build a release candidate. We track them by assigning the
blocked release to the issue's milestone before the issue is resolved.
The release manager should triage what does and does not block a release. The
list of release-blocking issues is available at the [milestone status
page](https://github.com/apache/beam/milestones). Triage each unresolved issue
with one of the following resolutions:
- An issue should not block the release if the problem exists in the current
released version or is a bug in new functionality that does not exist in the
current released version.
- An issue should be a blocker if the problem is a regression between the
currently released version and the release in progress and has no easy
workaround.
For all GitHub issues:
- If the issue has been resolved and the GitHub issue was not updated,
resolve it accordingly.
For issues with type "Bug" or labeled "flaky":
- If the issue is a known continuously failing test, it is not acceptable to
defer this until the next release. Please work with the Beam community to
resolve the issue.
- If the issue is a known flaky test, make an attempt to delegate a fix.
However, if the issue may take too long to fix (to the discretion of the
release manager):
- Delegate manual testing of the flaky issue to ensure no release blocking issues.
- Update the milestone to the version of the next release.
Please consider discussing this with stakeholders and the dev@ mailing
list, as appropriate.
For all other GitHub issues:
- If the issue has not been resolved and it is acceptable to defer this until the next release, update the milestone 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 Beam community to resolve the issue.
If there is a bug found in the RC creation process/tools, those issues should
be considered high priority and fixed in 7 days.
### Review cherry-picks
The release manager is empowered to triage issues, and accept or reject
cherry-picks to the release branch. Cherry picks are necessary if there are
outstanding issues at time of the release branch cut, or issues were found in
verification.
Check if there are outstanding cherry-picks into the release branch, [e.g. for
`2.14.0`](https://github.com/apache/beam/pulls?utf8=%E2%9C%93&q=is%3Apr+base%3Arelease-2.14.0).
Make sure they have blocker Issues attached and are OK to get into the release
by checking with community if needed.
You are encouraged to ask the following questions to be answered on each
cherry-pick PR and you can choose to reject cherry-pick requests if these
questions are not satisfactorily answered:
- Is this a regression from a previous release? (If no, fix could go to a
newer version.)
- Is this a new feature or related to a new feature? (If yes, fix could go to
a new version.)
- Would this impact production workloads for users? (E.g. if this is a direct
runner only fix it may not need to be a cherry pick.)
- What percentage of users would be impacted by this issue if it is not fixed?
(E.g. If this is predicted to be a small number it may not need to be a
cherry pick.)
- Would it be possible for the impacted users to skip this version? (If users
could skip this version, fix could go to a newer version.)
It is important to accept major/blocking fixes to isolated issues to make a
higher quality release. However, beyond that each cherry pick will increase
the time required for the release and add more last minute code to the release
branch. Neither late releases nor not fully tested code will provide positive
user value.
> **Tip**: Another tool in your toolbox is the known issues section of the
> release blog. Consider adding known issues there for minor issues instead of
> accepting cherry picks to the release branch.
## Build a release candidate
From the release branch, building a candidate involves selecting a commit,
tagging that commit, and building the various artifacts against that commit.
You can also run verifications against the RC commit (verification will also
occur during voting phase).
#### Checklist before proceeding
- [ ] There are no release blocking GitHub issues.
- [ ] There are no open pull requests to release branch.
- [ ] Release Manager’s GPG key is published to `dist.apache.org`.
- [ ] Release Manager’s GPG key is configured in `git` configuration.
- [ ] Set `SIGNING_KEY` to the public key of the Manager's GPG key.
- [ ] Release Manager has `org.apache.beam` listed under `Staging Profiles` in Nexus.
- [ ] Release Manager’s Nexus User Token is configured in `settings.xml`.
- [ ] Set `JAVA_HOME` to JDK 8 (Example: `export JAVA_HOME=/example/path/to/java/jdk8`).
- [ ] Have Java 11 installed.
### Tag a chosen commit for the RC
Release candidates are built from single tagged commits off the release branch.
When you have identified a good commit on the release branch, run
[choose_rc_commit.sh](https://github.com/apache/beam/blob/master/release/src/main/scripts/choose_rc_commit.sh)
to set it up correctly.
./release/src/main/scripts/choose_rc_commit.sh \
--release "${RELEASE_VERSION}" \
--rc "${RC_NUM}" \
--commit "${COMMIT_REF}" \
--clone \
--push-tag
You can do a dry run by omitting the `--push-tag` flag. Then it will only clone
the repo, adjust the version, and add the tag locally. If it looks good, run it
again with `--push-tag`. If you already have a clone that includes the
`${COMMIT_REF}` then you can omit `--clone`. This is perfectly safe since the
script does not depend on the current working tree.
See the source of the script for more details, or to run commands manually in
case of a problem.
The final state of the repository after an RC commit is chosen should match
this diagram:
<img src="images/tag-rc-commit.png" alt="Set version to non-SNAPSHOT, non-dev, on tagged RC commit" width="100%" />
The following should be confirmed:
- [ ] The release branch is unchanged.
- [ ] There is a commit not on the release branch with the version adjusted.
- [ ] The RC tag points to that commit.
### Run build_release_candidate GitHub Action to create a release candidate
**Action** [build_release_candidate](https://github.com/apache/beam/actions/workflows/build_release_candidate.yml) (click `run workflow`)
**The action will:**
1. Clone the repo at the selected RC tag.
2. Run gradle publish to push java artifacts into Maven staging repo.
3. Build and push java and python source distribution into [dist.apache.org](https://dist.apache.org/repos/dist/dev/beam).
4. Stage SDK docker images to [docker hub Apache
organization](https://hub.docker.com/search?q=apache%2Fbeam&type=image).
5. Build javadoc, pydoc, typedocs for a PR to update beam-site.
- **NOTE**: Do not merge this PR until after an RC has been approved (see
"Finalize the Release").
### Verify source distributions
- [ ] Verify that the source zip of the whole project is present in [dist.apache.org](https://dist.apache.org/repos/dist/dev/beam).
- [ ] Verify that the Python binaries are present in [dist.apache.org](https://dist.apache.org/repos/dist/dev/beam).
### Verify docker images
At
[https://hub.docker.com/u/apache](https://hub.docker.com/search?q=apache%2Fbeam&type=image),
visit each repository and navigate to "tags" tab. Verify images are pushed
with tags: `${RELEASE_VERSION}rc{RC_NUM}`
Verify that third party licenses are included in Docker. You can do this with a simple script:
RC_TAG=${RELEASE_VERSION}rc{RC_NUM}
for pyver in 3.8 3.9 3.10 3.11; do
docker run --rm --entrypoint sh \
apache/beam_python${pyver}_sdk:${RC_TAG} \
-c 'ls -al /opt/apache/beam/third_party_licenses/ | wc -l'
done
for javaver in 8 11 17; do
docker run --rm --entrypoint sh \
apache/beam_java${pyver}_sdk:${RC_TAG} \
-c 'ls -al /opt/apache/beam/third_party_licenses/ | wc -l'
done
And you may choose to log in to the containers and inspect:
docker run --rm -it --entrypoint=/bin/bash \
apache/beam_java${ver}_sdk:${RC_TAG}
ls -al /opt/apache/beam/third_party_licenses/
### Publish Java staging artifacts (manual)
1. Log in to the [Apache Nexus](https://repository.apache.org/#stagingRepositories) website.
2. Navigate to Build Promotion -> Staging Repositories (in the left sidebar).
3. Select repository `orgapachebeam-NNNN`.
4. Click the Close button.
5. When prompted for a description, enter “Apache Beam, version X, release candidate Y”.
6. Review all staged artifacts on `https://repository.apache.org/content/repositories/orgapachebeam-NNNN/`.
They should contain all relevant parts for each module, including `pom.xml`, jar, test jar, javadoc, etc.
Artifact names should follow [the existing format](https://search.maven.org/#search%7Cga%7C1%7Cg%3A%22org.apache.beam%22) in which artifact name mirrors directory structure, e.g., `beam-sdks-java-io-kafka`.
Carefully review any new artifacts.
Some additional validation should be done during the rc validation step.
### Upload `rc` artifacts to PyPI
This step uploads artifacts such as `apache-beam-${RELEASE_VERSION}rc${RC_NUM}`
to PyPI, so the RC artifacts can be depended upon directly by consumers, for
ease of RC verification.
**Action** [deploy_release_candidate_pypi](https://github.com/apache/beam/actions/workflows/deploy_release_candidate_pypi.yaml) (click `run workflow`)
**The Action will:**
Download previously build python binary artifacts Deploy release candidate
to PyPI with an `rc` suffix.
__Attention:__ Verify that:
- [ ] The File names version include ``rc-#`` suffix
- [ ] [Download Files](https://pypi.org/project/apache-beam/#files) have:
- [ ] All wheels uploaded as artifacts
- [ ] Release source's zip published
- [ ] Signatures and hashes do not need to be uploaded
### Propose pull requests for website updates
Beam publishes API reference manuals for each release on the website. For Java
and Python SDKs, that’s Javadoc and PyDoc, respectively. The final step of
building the candidate is to propose website pull requests that update these
manuals. The first pr will get created by the build_release_candidate action,
you will need to create the second one manually
Merge the pull requests only after finalizing the release. To avoid invalid
redirects for the 'current' version, merge these PRs in the order listed. Once
the PR is merged, the new contents will get picked up automatically and served
to the Beam website, usually within an hour. A committer can manually trigger
the
[beam_PostCommit_Website_Publish](https://ci-beam.apache.org/job/beam_PostCommit_Website_Publish/)
task in Jenkins to avoid waiting.
**PR 1: apache/beam-site**
This pull request is against the `apache/beam-site` repo, on the `release-docs`
branch ([example](https://github.com/apache/beam-site/pull/603)). It is
created by the `build_release_candidate` workflow (see above).
**PR 2: apache/beam**
This pull request is against the `apache/beam` repo, on the `master` branch
([example](https://github.com/apache/beam/pull/17378)).
- Update `CHANGES.md` to update release date and remove template.
- Update release version in `website/www/site/config.toml`.
- Add new release in `website/www/site/content/en/get-started/downloads.md`.
- Download links will not work until the release is finalized.
- Update links to prior releases to point to https://archive.apache.org (see
example PR).
- Create the Blog post:
#### Blog post
Use the template below to write a blog post for the release. See
[beam-2.31.0.md](https://github.com/apache/beam/commit/a32a75ed0657c122c6625aee1ace27994e7df195#diff-1e2b83a4f61dce8014a1989869b6d31eb3f80cb0d6dade42fb8df5d9407b4748)
as an example.
- Copy the changes for the current release from `CHANGES.md` to the blog post
and edit as necessary.
- Be sure to add yourself to
[authors.yml](https://github.com/apache/beam/blob/master/website/www/site/data/authors.yml)
if necessary.

If there are any issues found in the release candidate, reply on the vote
thread to cancel the vote. There’s no need to wait 72 hours. Go back to
["Stabilize the Release Branch"](#stabilize-the-release-branch) and address the problem. However, some issues
don’t require cancellation. For example, if an issue is found in the website
pull request, just correct it on the spot and the vote can continue as-is.
### Run validation tests
The community is responsible for performing validation, but as release manager
you are expected to contribute as well. Please see the [RC Testing Guide](https://github.com/apache/beam/blob/master/contributor-docs/rc-testing-guide.md)
for ideas on helping validate testing on downstream projects.
Before accepting an RC, as a community we try to exercise most (if not all) of
the tests listed in this
[spreadsheet](https://s.apache.org/beam-release-validation), and those are good
validations for you to try out as release manager. The goal of these tests is
to validate that we're able to run basic pipelines from a variety of
environments (not just our CI environment).
Since there are many tests, we recommend you running some validations using an
automation script. In case of script failure, you can still run all of them
manually.
You may need to have Python interpreters for all supported Python minor
versions to run all of the tests. See Python installation tips in [Developer
Wiki](https://cwiki.apache.org/confluence/display/BEAM/Python+Tips#PythonTips-InstallingPythoninterpreters).
> **Note**
> The community's validation means more than just running the tests
> that we have already run. It includes users trying out the RC on their own
> downstream tests. It also includes double checking that our human-language
> instructions actually still correspond to the automation that we have built.
#### Run validations using run_rc_validation.sh
**Script:** [run_rc_validation.sh](https://github.com/apache/beam/blob/master/release/src/main/scripts/run_rc_validation.sh)
**Usage**
1. First update required configurations listed in `RC_VALIDATE_CONFIGS` in
[script.config](https://github.com/apache/beam/blob/master/release/src/main/scripts/script.config)
2. Then run
```
./release/src/main/scripts/run_rc_validation.sh
```
**Note:** running the validations requires the ability to do the following in your GCP account: start pipelines,
write to BigQuery, and create a cluster of machines for running containers (for x-lang validation).
**Tasks included**
1. Create a PR to trigger Python validation job, including
* Python quickstart in batch and streaming mode with direct runner and Dataflow runner.
* Python Mobile Games(UserScore, HourlyTeamScore) with direct runner and Dataflow runner.
2. Run Python Streaming MobileGames, includes
* Start a new terminal to run Java Pubsub injector.
* Start a new terminal to run Python LeaderBoard with Direct Runner.
* Start a new terminal to run Python LeaderBoard with Dataflow Runner.
* Start a new terminal to run Python GameStats with Direct Runner.
* Start a new terminal to run Python GameStats with Dataflow Runner.
3. Multi-language pipelines validation, includes
* Running the Python quickstart example using Python portable DirectRunner. This will start a new terminal for the Java expansion service.
* Running the Java quickstart example using Python portable DirectRunner. This will start new terminals for the Python expansion service and the job server.
* Start a new terminal to run Python multi-language Java kafka validation with Dataflow Runner.
* Start a new terminal to run Python multi-language Java sql validation with Dataflow Runner.
* **Tasks you need to do manually**.
- [ ] Check whether validations succeed by following console output instructions.
- [ ] Terminate streaming jobs and java injector.
- [ ] Run Java quickstart (wordcount) and mobile game examples with the staged artifacts. The easiest way to do this is by running the tests on GitHub Actions.
- Other manual validation will follow, but this will at least validate that the staged artifacts can be used.
* Go to https://github.com/apache/beam/actions/workflows/beam_PostRelease_NightlySnapshot.yml/.
* Click "Run Workflow".
* Set `RELEASE` to `2.xx.0`, and set `SNAPSHOT_URL` to point to the staged artifacts in Maven central (https://repository.apache.org/content/repositories/orgapachebeam-NNNN/).
* Click "Build".
- [ ] Sign up [spreadsheet](https://s.apache.org/beam-release-validation).
- [ ] Vote in the release thread.

### Checklist to proceed to the next step
- [ ] Issues identified during vote have been resolved, with fixes committed to the release branch.
- [ ] All issues in the current release's milestone should be closed.
- [ ] Community votes to release the proposed candidate, with at least three approving PMC votes.
----
## Finalize the release
Once the release candidate has been reviewed and approved by the community, the release should be finalized.
This involves the final deployment of the release candidate to the release repositories, merging of the website changes, etc.
This does not take very long, and can be accomplished within hours of the vote being finalized.
### Deploy artifacts to Maven Central Repository
Use the [Apache Nexus repository manager](https://repository.apache.org/#stagingRepositories) to release the staged binary artifacts to the Maven Central repository.
In the `Staging Repositories` section, find the relevant release candidate `orgapachebeam-XXX` entry and click `Release`.
Drop all other release candidates that are not being released.
### Deploy Python artifacts to PyPI, Docker Images to DockerHub, and Tag Release
* **GitHub Action:** [finalize_release](https://github.com/apache/beam/actions/workflows/finalize_release.yml)
After running the action, perform the following checks:
* Verify that the files at https://pypi.org/project/apache-beam/#files are correct.
All wheels should be published, in addition to the zip of the release source.
(Signatures and hashes do _not_ need to be uploaded.)
* Images are published at [DockerHub](https://hub.docker.com/search?q=apache%2Fbeam&type=image) with tags {RELEASE_VERSION} and *latest*.
* Images with *latest* tag are pointing to current release by confirming the digest of the image with *latest* tag is the same as the one with {RELEASE_VERSION} tag.
* `v{RELEASE_VERSION}` and `sdks/v{RELEASE_VERSION}` tags should be visible on Github's [Tags](https://github.com/apache/beam/tags) page.
### Merge Website pull requests
Merge all of the website pull requests
- [listing the release](/get-started/downloads/)
- publishing the [Python API reference manual](https://beam.apache.org/releases/pydoc/) and the [Java API reference manual](https://beam.apache.org/releases/javadoc/), and
- adding the release blog post.
### Publish release to Github
Once the tag is uploaded, publish the release notes to Github. From the [Beam release page on Github](https://github.com/apache/beam/releases) select
"Draft a new release." Title the release "Beam ${RELEASE_VERSION} release" and set the release at the version tag created above. Use the content of the
release blog post as the body of the release notes, set this version as the latest release, and publish it.
The release notes should now be visible on Github's [Releases](https://github.com/apache/beam/releases) page.
### Mark the version as released in GitHub
In GitHub, in the [milestone page](https://github.com/apache/beam/milestones), click close on the current release.
### PMC-Only Finalization
There are a few release finalization tasks that only PMC members have permissions to do.
Ping [dev@](mailto:dev@beam.apache.org) mailing list for assistance if you need it.
#### Deploy source release to dist.apache.org
Copy the source release from the `dev` repository to the `release` repository at `dist.apache.org` using Subversion.
```
svn co https://dist.apache.org/repos/dist/dev/beam dev # Checkout the `dev` artifact repo.
svn co https://dist.apache.org/repos/dist/release/beam release # Checkout the `release` artifact repo.
mkdir release/$RELEASE_VERSION
# Copy files from the `dev` artifact repo to the `release` artifact repo.
cd release
svn add $RELEASE_VERSION
svn rm $OLD_RELEASE_VERSION # Delete all artifacts from old releases.
svn commit -m "Adding artifacts for the ${RELEASE_VERSION} release and removing old artifacts"
```
Make sure the last release's artifacts have been copied from `dist.apache.org` to `archive.apache.org`.
This should happen automatically: [dev@ thread](https://lists.apache.org/thread.html/39c26c57c5125a7ca06c3c9315b4917b86cd0e4567b7174f4bc4d63b%40%3Cdev.beam.apache.org%3E) with context.
#### Recordkeeping with ASF
Use [reporter.apache.org](https://reporter.apache.org/addrelease.html?beam) to seed the information about the release into future project reports.
### Checklist to proceed to the next step
- [ ] Maven artifacts released and indexed in the [Maven Central Repository](https://search.maven.org/#search%7Cga%7C1%7Cg%3A%22org.apache.beam%22)
- [ ] Source distribution available in the release repository of [dist.apache.org](https://dist.apache.org/repos/dist/release/beam/)
- [ ] Source distribution removed from the dev repository of [dist.apache.org](https://dist.apache.org/repos/dist/dev/beam/)
- [ ] Website pull request to [list the release](/get-started/downloads/) and publish the [API reference manual](https://beam.apache.org/releases/javadoc/) merged.

- [ ] Release version is listed at reporter.apache.org
**********
## 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.
### Apache mailing lists
Announce on the dev@ mailing list that the release has been finished.
Announce on the release on the user@ mailing list, listing major improvements and contributions.
Announce the release on the announce@apache.org mailing list.
__NOTE__: This can only be done from `@apache.org` email address. This email has to be in plain text (no HTML tags).
### Social media
Tweet, post on Facebook, LinkedIn, and other platforms.
Ask other contributors to do the same.
Also, update [the Wikipedia article on Apache Beam](https://en.wikipedia.org/wiki/Apache_Beam).
### Checklist to declare the process completed
- [ ] Release announced on the user@ mailing list.
- [ ] Blog post published, if applicable.
- [ ] Release recorded in reporter.apache.org.
- [ ] Release announced on social media.
- [ ] Completion declared on the dev@ mailing list.
- [ ] Update Wikipedia Apache Beam article.
**********
## Post-Release Tasks
At the end of the release, go to the GitHub milestones page and mark the recently released version as closed.
#### Update the Java BOM
Google releases a BOM that pins compatible versions of their Java libraries.
After the release, try updating the BOM to the latest version.
To do so, create a draft PR and run test suites following the instructions at
https://github.com/apache/beam/blob/master/contributor-docs/java-dependency-upgrades.md.
Triage the test failures and rerun any tests that seem potentially unrelated to the upgrade.
If there are no test failures due to the BOM upgrade, request review and merge the PR as normal.
If there are test failures due to the BOM upgrade, email the dev list and ask for a volunteer to take the update forward.
It is not your responsibility to fix the BOM issues or to find a volunteer (though you are welcome to take it forward).
If nobody volunteers, that is OK and this issue can roll forward to the next release.
You can optionally use the following template for your email to the dev list:
```
From: Release Manager
To: dev@beam.apache.org
Subject: Java BOM Update X.Y.Z
Hi everyone,
Following the instructions in https://github.com/apache/beam/blob/master/contributor-docs/release-guide.md#post-release-tasks
I've attempted to update the Java Google BOM and have run into test issues caused by the upgrade [1].
Since the Java Google BOM update is best effort for a release manager, I'm handing this piece off to the community.
If you would like to volunteer to help, you can get started by following the instructions in
https://github.com/apache/beam/blob/master/contributor-docs/java-dependency-upgrades.md#google-cloud-related-dependency-upgrades
otherwise this will roll over to the next release.
Thanks,
Release Manager
[1] https://github.com/apache/beam/pull/123
```
### Update Beam Playground
After new Beam Release is published, Beam Playground can be updated following the steps below:
1. Open the [Cloud Build triggers in apache-beam-testing](https://console.cloud.google.com/cloud-build/triggers?project=apache-beam-testing) GCP project.
2. Find the trigger "Deploy-Update-Playground-environment-stg":
1. Click on the trigger name to open its settings

4. Test updated [staging Playground](https://play-dev.beam.apache.org/) in a browser
1. Open the menu (represented by '...' in the right top corner) and click on Versions. Validate that commit is the same for all listed containers, and the hash belongs to a [recent master branch commit](https://github.com/apache/beam/commits/master)
2. For each of the supported SDKs (Java, Python, Go, SCIO):
* Switch to the SDK
* Make any changes to the loaded default example
* Click the Run button
* Wait for successful completion
* Click "Share My Code" to ensure that the link is generated
5. Repeat the same steps for "Deploy-Update-Playground-environment-prod" trigger as for "Deploy-Update-Playground-environment-stg" trigger
6. Repeat the same steps for "Playground-CD-stable-manual-prod" trigger as for "Playground-CD-stable-manual-stg" trigger
7. Test updated [prod Playground](https://play.beam.apache.org/) in a browser. The process is similar to the staging environment.
8. Find the trigger "Playground-CI-stable"
1. Click on the trigger name to open its settings
2. Set the value for the _BEAM_VERSION variable (Advanced -> Substitution Variables) to the actual version of Beam SDK (e.g., 2.47.0)

### Improve the process
It is important that we improve the release processes over time.
Once you’ve finished the release, please take a step back and look what areas of this process and be improved. Perhaps some part of the process can be simplified.
Perhaps parts of this guide can be clarified.
If we have specific ideas, please start a discussion on the dev@ mailing list and/or propose a pull request to update this guide.
Thanks!
