Release numbering

The Forgejo release numbers are composed of the Gitea release number followed by a dash and a serial number. For instance:

• Gitea v1.20.0 will be Forgejo v1.20.0-0, v1.20.0-1, etc

The Gitea release candidates are suffixed with -rcN which is handled as a special case for packaging: although X.Y.Z is lexicographically lower than X.Y.Z-rc1 is is considered greater. The Forgejo serial number must therefore be inserted before the -rcN suffix to preserve the expected version ordering.

• Gitea v1.20.0-rc0 will be Forgejo v1.20.0-0-rc0, v1.20.0-1-rc0
• Gitea v1.20.0-rc1 will be Forgejo v1.20.0-2-rc1, v1.20.0-3-rc1, v1.20.0-4-rc1
• Gitea v1.20.0 will be Forgejo v1.20.0-5, v1.20.0-6, v1.20.0-7
• etc.

Because Forgejo depends on Gitea, it must retain the same release numbering scheme to be compatible with libraries and tools that depend on it. For instance, the tea CLI or the Gitea SDK will behave differently depending on the server version they connect to. If Forgejo had a different numbering scheme, it would no longer be compatible with the Gitea ecosystem.

From a Semantic Versioning standpoint, all Forgejo releases are pre-releases because they are suffixed with a dash. They are syntactically correct but do not comply with the Semantic Versioning recommendations. Gitea is not compliant either and Forgejo inherits this problem.

Release process

The TL;DR: to publish a vX.Y.Z-N release is to:

• Push the vX.Y.Z-N tag to https://codeberg.org/forgejo-integration/forgejo to trigger a workflow that will publish the release in https://codeberg.org/forgejo-experimental/forgejo
• Give it some time for people to try it out
• Push the vX.Y.Z-N tag to https://forgejo.octopuce.forgejo.org/forgejo-release/forgejo to trigger a workflow that will sign the release from https://codeberg.org/forgejo-experimental/forgejo and publish it in https://codeberg.org/forgejo-release/forgejo

Semantic version

• Update the FORGEJO_VERSION variable in the Makefile

Create a milestone and a check list

• Create a Forgejo vX.X.Z-N milestone set to the date of the release
• Create an issue named [RELEASE] Forgejo vX.Y.Z-N with a description that includes a list of what needs to be done for the release with links to follow the progress
• Set the milestone of this issue to Forgejo vX.X.Z-N
• Close the milestone when the release is complete

Cherry pick the latest commits from Gitea

The vX.Y/forgejo branch is populated as part of the rebase on top of Gitea. The release happens in between rebase and it is worth checking if the matching Gitea branch, release/vX.Y contains commits that should be included in the release.

• cherry-pick -x the commits
• push the vX.Y/forgejo branch including the commits
• verify that the tests pass

Release Notes

• Add an entry in RELEASE-NOTES.md

Forgejo release building and testing

When Forgejo is released, artefacts (packages, binaries, etc.) are first published by the CI/CD pipelines in the https://codeberg.org/forgejo-experimental organization, to be downloaded and verified to work.

• Locally set the vX.Y.Z-N tag to the tip of the https://codeberg.org/forgejo/forgejo/vX.Y/forgejo branch
• Push the vX.Y.Z-N tag to https://codeberg.org/forgejo-integration/forgejo

Binaries are built and uploaded to https://codeberg.org/forgejo-integration/forgejo/releases Container images are built and uploaded to https://codeberg.org/forgejo-integration/-/packages/container/forgejo/versions

If the release is successfully built, it will be copied to https://codeberg.org/forgejo/forgejo-experimental. Otherwise the logs of the workflow that tried to build the release in https://codeberg.org/forgejo-integration/forgejo/actions contains the error that needs fixing.

Fork the Forgejo infrastructure repository, modify it to use the experimental release and push the branch. It will trigger a workflow to deploy the release and run high level integration tests.

Reach out to packagers and users to manually verify the release works as expected.

Forgejo release publication

• Push the vX.Y.Z-N tag to https://forgejo.octopuce.forgejo.org/forgejo/forgejo

It will trigger a workflow to:

• Push the vX.Y.Z-N tag to https://codeberg.org/forgejo/forgejo
• Downoad Binaries from https://codeberg.org/forgejo-experimental, sign them and copy them to https://codeberg.org/forgejo
• Copy container images from https://codeberg.org/forgejo-experimental to https://codeberg.org/forgejo

Forgejo runner publication

• Push the vX.Y.Z-N tag to https://code.forgejo.org/forgejo/runner

The release is built on https://code.forgejo.org/forgejo-integration/runner, which is a mirror of https://code.forgejo.org/forgejo/runner.

The release is published on https://forgejo.octopuce.forgejo.org/forgejo/runner, which is a mirror of https://code.forgejo.org/forgejo-integration/runner. It is behind a VPN and its role is to copy and sign release artifacts.

• Binaries are downloaded from https://code.forgejo.org/forgejo-integration/runner, signed and copied to https://code.forgejo.org/forgejo/runner.
• Container images are copied from https://code.forgejo.org/forgejo-integration to https://code.forgejo.org/forgejo

If the publishing the release needs debug, it can be done manually:

• https://forgejo.octopuce.forgejo.org/forgejo-release/runner-debug has the same secrets as https://forgejo.octopuce.forgejo.org/forgejo-release/runner
• Make the changes, tag with vX.Y.Z-N and force push the tag to https://forgejo.octopuce.forgejo.org/forgejo-release/runner-debug
• Watch the action run at https://forgejo.octopuce.forgejo.org/forgejo-release/runner-debug/actions
• To skip one of the publish phases (binaries or container images), delete it and commit in the repository before pushing the tag
• Reflect the changes in a PR at https://code.forgejo.org/forgejo/runner to make sure they are not lost

Securing the release token and cryptographic keys

For both the Forgejo runner and Forgejo itself, copying and signing the release artifacts (container images and binaries) happen on a Forgejo isntance running behind a VPN to safeguard the token that has write access to the Forgejo repository as well as the cryptographic key used to sign the releases.

Website update

• Restart the last CI build at https://codeberg.org/forgejo/website/src/branch/main/
• Verify https://forgejo.org/download/ points to the expected release
• Update the documentation link to the latest version
• Manually try the instructions to work

DNS update

• Update the release.forgejo.org TXT record that starts with forgejo_versions= to be forgejo_versions=vX.Y.Z-N

Standard toot

The following toot can be re-used to announce a minor release at https://floss.social/@forgejo. For more significant releases it is best to consider a dedicated and non-standard toot.

#Forgejo vX.Y.Z-N was just released! This is a minor patch. Check out the release notes and download it at https://forgejo.org/releases/. If you experience any issues with this release, please report to https://codeberg.org/forgejo/forgejo/issues.

Release signing keys management

A GPG master key with no expiration date is created and shared with members of the Owners team via encrypted email.

Users, organizations and repositories

Shared user: release-team

The release-team user publishes and signs all releases. The associated email is mailto:release@forgejo.org.

The public GPG key used to sign the releases is EB114F5E6C0DC2BCDD183550A4B61A2DC5923710 Forgejo Releases <release@forgejo.org>

Shared user: forgejo-ci

The forgejo-ci user is dedicated to https://forgejo-ci.codeberg.org/ and provides it with OAuth2 credentials it uses to run.

Shared user: forgejo-experimental-ci

The forgejo-experimental-ci user is dedicated to provide the application tokens used by Woodpecker CI repositories to build releases and publish them to https://codeberg.org/forgejo-experimental. It does not (and must not) have permission to publish releases at https://codeberg.org/forgejo.

Integration and experimental organization

The https://codeberg.org/forgejo-integration organization is dedicated to integration testing. Its purpose is to ensure all artefacts can effectively be published and retrieved by the CI/CD pipelines.
