Release management

Release cycle

See the release schedule.

Stable release support

Bug fixes and security fixes are backported to the latest stable release.

Long Term Support (LTS)

The first quarter release of the year is LTS. Critical bug fixes and security fixes are backported to the latest LTS release.

Experimental releases

Experimental releases are published daily in forgejo-experimental organization. They are built from the tip of the branch of each stable release. For instance:

  • forgejo is X.Y-test where X.Y is the major and minor number of the next stable release.
  • v8.0/forgejo is 8.0-test
  • v7.0/forgejo is 7.0-test

Release numbering

The Forgejo release numbers are compliant with Semantic Versioning. They are followed by the Gitea release number with which they compatible. For instance:

  • Forgejo v7.0.5+gitea-1.21.0 is compatible with Gitea v1.21.0.

The release candidates are built of the stable branch and published with the -test suffix:

  • Forgejo v7.0-test
  • Forgejo v8.0-test
  • Forgejo v8.1-test
  • etc.

Stable release process

  • Three weeks before the release date announce a feature freeze during which only bug fixes can be merged
  • Create a new issue based on the checklist of the previous release (for instance v8.0.0) and follow the same steps

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.

It will trigger a build workflow that:

If the build fails, the logs of the workflow can be found in https://codeberg.org/forgejo-integration/forgejo/actions for debugging. Once the build is successful, it must be copied to https://codeberg.org/forgejo-experimental.

It will trigger a publish workflow that:

To verify the container images, the end-to-end integration tests can be used. Push a branch with the location of the release under test to run a collection of test workflows.

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

LTS toolchain upgrades

The Forgejo toolchain relies on Go OCI images based on Alpine. Only the last two Alpine versions are supported and will be EOL before the Forgejo LTS. In order to receive security updates the toolchain needs to be upgraded to a supported Alpine and Go version because it goes EOL.

Automated experimental releases

The Forgejo development and stable branches are pushed daily to the forgejo-integration. It triggers the release build workflow which creates a new release for each updated branch, based on their latest commit:

  • the forgejo branch creates the X.Y-test release where X.Y is based on the most recent tag. For instance:
    • the tag v8.0.0-dev will create the 8.0-test release
    • the tag v8.1.0-dev will create the 8.1-test release
  • the v*/forgejo branches create X.Y-test releases where X.Y is based on their name. For instance:
    • the branch v7.0/forgejo will create the 7.0-test release
    • the branch v7.1/forgejo will create the 7.1-test release

Forgejo release mirror

The https://code.forgejo.org/forgejo/forgejo repository is a read-only mirror updated daily with the release assets and the branches from https://codeberg.org/forgejo/forgejo.

Forgejo runner publication

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 has no public IP and its role is to copy and sign release artifacts.

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

It can also be done from the CLI with forgejo-runner exec and providing the secrets from the command line.

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. A subkey with a one year expiration date is created and stored in the secrets repository (openpgp/20??-release-team.gpg), to be used by the release pipeline. The public master key is stored in the secrets repository and published where relevant (keys.openpgp.org for instance).

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 instance not publicly accessible to safeguard the token that has write access to the Forgejo repository as well as the cryptographic key used to sign the releases.

Master key creation

  • gpg —expert —full-generate-key
  • key type: ECC and ECC option with Curve 25519 as curve
  • no expiration
  • id: Forgejo Releases contact@forgejo.org
  • gpg —export-secret-keys —armor EB114F5E6C0DC2BCDD183550A4B61A2DC5923710 and send via encrypted email to Owners
  • gpg —export —armor EB114F5E6C0DC2BCDD183550A4B61A2DC5923710 > release-team.gpg.pub
  • gpg —keyserver keys.openpgp.org —send-keys EB114F5E6C0DC2BCDD183550A4B61A2DC5923710
  • commit to the secrets repository

Subkey creation and renewal

  • gpg —expert —edit-key EB114F5E6C0DC2BCDD183550A4B61A2DC5923710
  • addkey
  • key type: ECC (signature only)
  • elliptic curve Curve 25519
  • key validity: 18 months
  • update https://codeberg.org/forgejo/forgejo/issues/58 to schedule the renewal 12 months later
  • gpg —export —armor EB114F5E6C0DC2BCDD183550A4B61A2DC5923710 > openpgp/release-team.gpg.pub
  • commit to the secrets repository
  • gpg —keyserver keys.openpgp.org —send-keys EB114F5E6C0DC2BCDD183550A4B61A2DC5923710

Local sanity check

From the root of the secrets directory, assuming the master key for EB114F5E6C0DC2BCDD183550A4B61A2DC5923710 is already imported in the keyring.

There are a lot of contradictory information regarding the management of subkeys, with zillions ways of doing something that looks like it could work but creates situations that are close to impossible to figure out. Experimenting with the CLI, reading the gpg man page and using common sense is the best way to understand how it works. Reading the documentation or discussions on the net is highly confusing because it is loaded with 20 years of history, most of which is no longer relevant.

Here are a few notions that help understand how it works:

  • gpg --export-secret-subkeys --armor B3B1F60AC577F2A2! exports the secret key for the subkey B3B1F60AC577F2A2, the exclamation mark meaning “nothing else”.
  • a keygrip is something that each private key has and that can be displayed with gpg --with-keygrip --list-key. It matters because each private key is associated with exactly one file in the private-keys-v1.d directory which is named after this keygrip. It is the best way to verify an unrelated private key was not accidentally included in the export of the subkey.
  • when a subkey is created, the public key for the master key must be published again because it includes the public key of this new subkey.
  • all the instructions that are published to instruct people to verify the signature of a release use the fingerprint of the master key. It will work although the release really is signed by the subkey and not the master key. This is the main benefit of using subkeys as it hides the rotation of the subkeys and does not require updating instructions everywhere every year.
  • whenever gpg starts working with a new directory, it will launch a gpg-agent daemon that will persist. If this directory is removed manually or modified it will confuse the daemon and the gpg command will misbehave in ways that can be very difficult to understand. When experimenting create a new directory but do not modify the files manually, even though some instructions on the net recommend doing so, for instance to remove a private key.
