Automated jobs may pin the fingerprint as well. *If you have the fingerprint pinned, you will need to take action otherwise Mercurial will refuse the connect to <a href="http://hg.mozilla.org">hg.mozilla.org</a> once the certificate is swapped.*<br></div><div><br></div><div>The easiest way to ensure your pinned fingerprint is up-to-date is to run `mach vcs-setup` from a Mercurial checkout (it can be from an old revision). If running Mercurial 3.9+ (which you should be in order to have security fixes), both the old and new fingerprints will be pinned and the transition will "just work." Otherwise you'll need to run `mach vcs-setup` or take further action after the new certificate is installed. If a new fingerprint is installed, run `mach vcs-setup` again after the transition to remove the old fingerprint.<br></div><div><br></div><div>Fingerprints and details of the new certificate (including hgrc config snippets you can copy) are located at <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=1495464#c6">https://bugzilla.mozilla.org/show_bug.cgi?id=1495464#c6</a><a href="https://bugzilla.mozilla.org/show_bug.cgi?id=1147548#c12" target="_blank"><span class="gmail-il"></span><span class="gmail-il"></span></a>. From a certificate level, this transition is pretty boring: just a standard certificate renewal from the same CA.<br></div><div><br></div><div>The IRC channel for this operational change will be #vcs. Fallout in Firefox CI should be discussed in #ci. Please track any bugs related to this change against bug 1495464.<br></div></div></div></div>
