This document is intended to be used and kept up to date by the Fedora Release Manager.  It details the steps necessary to perform an official release of Fedora.

The release version in the documentation below is identified as X.Y , replace this in the instructions with the current release (eg 4.0.1).
X is the major point version, Y is the minor point version, and Z is the maintenance point.

The previous release version (snapshot previous documentation) is identified as A.B , replace this with the previous release (eg 4.0).

Before Release Day

Verify release privileges

To make sure release day goes smoothly, you should ensure that:

  • You have an account with commit access for the fedora project on github. As a committer, you should already have this level of access.
  • You have an account with manager privileges on the Fedora Repository Drupal site.
  • You have an account with edit privileges on the Confluence wiki.
  • You have an account and have requested to be given permission to publish to the org.fcrepo groupId by adding a comment to the Fedora Sonatype Hosting Ticket
  • Your maven settings.xml includes the following:

Prepare and distribute test plan

The test plan should also be ready prior to code freeze.

It should include:

  • Which platform/configuration combinations will be tested
  • Which automated tests will be run, and by whom
  • Which manual tests will be run, and by whom
  • Which service compatibility tests (external search, external triplestore) will be run, and by whom
  • Instructions on how testers will report on test results

Create release branch and begin final test phase

Update online resources

If any online resources have been modified or added to during the release, these must be updated.

Release Day

Update the KEYS file

Make sure the KEYS file in subversion is up-to-date with the latest, exported public keys of the committers (and most importantly, the release manager).  For more information on this file, see this page.

For *nix systems use the following command to add a missing key to the KEYS file:
(gpg --list-sigs AB76196 && gpg -a --export AB76196) >> KEYS

Build and release the final distribution to Maven Central

In order to build the release make sure that:

  • you have a working PGP installation with your code signing key as the default key

Run the following commands to generate and upload all built artifacts to the Sonatype staging repository:

mvn release:clean
mvn release:prepare -DdryRun -DreleaseVersion=X.X.X -DdevelopmentVersion=X.X.Y-SNAPSHOT -DautoVersionSubmodules
mvn release:clean && mvn release:prepare -DreleaseVersion=X.X.X -DdevelopmentVersion=X.X.Y-SNAPSHOT -DautoVersionSubmodules -DpushChanges=false

Review the local commits for correctness

Push tags to GitHub

git push origin --tags

Download the release source and build locally

  • Remove/or move local Maven repository
mv ~/.m2/repository ~/.m2/repository-yyyy-mm-dd

Merge and commit to GitHub

git checkout -b <release-branch>
git push origin <release-branch>:master

Deploy to Sonatype

mvn release:perform -DperformRelease -Dgoals=deploy

Login to

Find the staging repository, check that it looks good, and "Close" it. Then "Release" it. This will publish the artifacts to the Sonatype releases repository and start the process of syncing them with central. The artifacts may take several hours to reach central. When finished, they'll be available at

Build GitHub documentation site

git checkout -b <site-release>
git cherry-pick <commit [maven-release-plugin] prepare release ...>
mvn site-deploy -DskipTests
** Resume from a given module, if necessary
mvn site-deploy -DskipTests -rf <module>

Create GitHub release

Under GitHub account/releases, select "Draft new release".

  • Write a description
  • Create MD5 and SHA1 files for each of the release artifacts

    For example
    sha1sum fcrepo-webapp-4.0.0-alpha-3.war |cut -f1 -d' ' > fcrepo-webapp-4.0.0-alpha-3.war.sha1
    md5sum fcrepo-webapp-4.0.0-alpha-3.war |cut -f1 -d' ' > fcrepo-webapp-4.0.0-alpha-3.war.md5
    sha1sum fcrepo-webapp-4.0.0-alpha-3-jetty-console.war |cut -f1 -d' ' > fcrepo-webapp-4.0.0-alpha-3-jetty-console.war.sha1
    md5sum fcrepo-webapp-4.0.0-alpha-3-jetty-console.war |cut -f1 -d' ' > fcrepo-webapp-4.0.0-alpha-3-jetty-console.war.md5
  • Upload artifacts to GitHub release (war, war.asc, war.md5, war.sha1)

Release related projects

Release other projects that are related to the main codebase, following the same process as outlined above.

  • fcrepo-jms-indexer-pluggable

Complete the Duraspace wiki documentation updates

Current Fedora Repository Documentation wiki:

At the very minimum, update the following:

Release Notes

If this is a new major or minor point release, copy the previous point release documentation to create the current wiki (/FEDORA XY ), then update accordingly. Mark the new pages as current, and update the pages in the previous documentation to indicate they are out-of-date.

If this is a maintenance point release, create separate child release note pages for each release covered by the documentation (see for an example).
Otherwise, post the release notes in the Release Notes page (see for an example).

Update any other documentation as needed, per changes/features added with this release.

Make sure the license and copyright information is up-to-date with this release.
