The Plone release process

Release process for Plone packages

To keep the Plone software stack maintainable, the Python egg release process must be automated to high degree. This happens by enforcing Python packaging best practices and then making automated releases using the zest.releaser tool.

This is extended with Plone coredev specific features by plone.releaser <>.

  • Anyone with necessary PyPi permissions must be able to make a new release by running the fullrelease command

… which includes …

  • All releases must be hosted on PyPI

  • All versions must be tagged at version control

  • Each package must have README.rst with links to the version control repository and issue tracker

  • CHANGES.rst (docs/HISTORY.rst respectively .txt in some packages) must be always up-to-date and must contain list of functional changes which may affect package users.

  • CHANGES.rst must contain release dates

  • README.rst and CHANGES.rst must be visible on PyPI

  • Released eggs must contain generated gettext .mo files, but these files must not be committed to the repository. The .mo files can be created with the zest.pocompile add-on, which should be installed together with zest.releaser.

  • .gitignore and must reflect the files going to egg (must include page template, po files)

Special packages

The Plone Release Team releases the core Plone packages. Several others also have the rights to release individual packages on If you have those rights on your account, you should feel free to make releases.

Some packages need special care or should be done only by specific people as they know what they are doing. These are:

Products.CMFPlone, Plone, and

Please leave these to the release managers, Eric Steele and Maurits van Rees.

Please leave this to the i18n team lead, Vincent Fretin.

Plone core release process checklist

  1. Check Jenkins Status

Check latest Plone coredev job on, it should be green, if it is not, fix the problem first.

  1. Check out buildout.coredev

git clone
cd buildout.coredev
git checkout 5.2
bin/buildout -c buildout.cfg
  1. Check Packages for Updates

Check all packages for updates, add to/remove from checkouts.cfg accordingly.

This script may help:

bin/manage report --interactive

This step should not be needed, because we do the check for every single commit (mr.roboto), but people may still have forgotten to add a package to the checkouts.cfg file. Also, the automatic check currently does not work.

  1. Check packages individually

Use the bin/fullrelease script from the core development buildout. This includes extra checks that we have added in plone.releaser. It guides you through all the next steps.

  1. Check changelog

    Check if CHANGES.rst is up-to-date, all changes since the last release should be included, a Fixes and/or New header should be included, with the relevant changes under it. Upgrade notes are best placed here as well. Compare git log HEAD...<LAST_RELEASE_TAG> with CHANGES.rst. Or from zest.releaser: lasttaglog <optional tag if not latest>.

  2. Run pyroma

  3. Run check-manifest

  4. Check package “best practices” (README.rst, CHANGES.rst, src directory)

  • Check if version in is correct and follows our versioning best practice

  1. Make a release (zest.releaser: bin/fullrelease)

  2. Remove packages from auto-checkout section in checkouts.cfg and update versions.cfg.

  1. Take care of a few special packages:

  2. Make sure contains an upgrade step for the future Plone release.

  3. Update CMFPlone version in profiles/default/metadata.xml Check that the version numbers of CMFPlone metadata.xml and latest upgrade step are in sync.

  4. Create a pending release (directory) on

  1. Copy all core packages there.

  2. Possibly make an alpha/beta release of CMFPlone.

  3. Copy the versions.cfg file from coredev there.

  1. Write an email to the Plone developers list announcing a pending release.

  2. Update version.

  3. Create a unified changelog

bin/manage changelog
  1. Make final release on (remove “-pending”)

  2. Update the “-latest” link on

  3. Create new release on launchpad (

  4. Create release page on

  5. Send links to installers list ( <>)

  6. Wait for installers to be uploaded to Launchpad, link on release page

  7. Publish release page on

  8. Update homepage links to point to new release

  9. Send out announcement to plone-announce

  10. Update #plone topic

  11. Ask the security team to update the page in the configuration control panel.

    (Configuration registry: plone.securitysupport, plone.versions, plone.activemaintenance)
