        description('''
This job is meant to be run after upstream 7.yy.x branches are available to start the new devspaces-3.y-rhel-8 github branches for the upcoming release.
<p>
See <a href=https://github.com/redhat-developer/devspaces/blob/devspaces-3-rhel-8/product/tagRelease.sh>
https://github.com/redhat-developer/devspaces/blob/devspaces-3-rhel-8/product/tagRelease.sh</a>

<p>Pass in values like these to create/update the ''' + PREV_VERSION + ''' and 3.x (''' + JOB_BRANCH + ''') branches, including devfiles in sample projects:
<ul>
    <li>DS_VERSION = ''' + PREV_VERSION + '''</li>
    <li>NEW_BRANCH = devspaces-''' + PREV_VERSION + '''-rhel-8</li>
    <li>MIDSTM_BRANCH = devspaces-3-rhel-8 (''' + JOB_BRANCH + ''')</li>
</ul>
</p>

<p>To create branches of pkgs.devel repos, open a ticket like <a href=https://projects.engineering.redhat.com/browse/SPMM-4820>SPMM-4820</a>

  <p>NOTE: this job is not meant to create tags in repos, as branching occurs BEFORE GA, and tagging occurs AFTER.
