+For Windows related changes, the main contact point is Brian

+For Android related changes, the main contact is Tapani

+For MacOSX related changes, Jeremy Huddleston Sequoia is currently a

<strong>Note:</strong> If a patch in the current queue needs any additional
fix(es), then they should be squashed together.

The commit messages and the <code>cherry picked from</code> tags must be preserved.

<h2>Regression/functionality testing</h2>
Less often (once or twice), shortly before the pre-release announcement.
Ensure that testing is redone if Intel devs have requested an exception, as per above.
</p>
+
<ul>
<li><em>no regressions should be observed for Piglit/dEQP/CTS/Vulkan on Intel platforms</em>
<li><em>no regressions should be observed for Piglit using the swrast, softpipe
and llvmpipe drivers</em>
</ul>
+
<p>
Currently testing is performed courtesy of the Intel OTC team and their Jenkins CI setup. Check with the Intel team over IRC how to get things setup.
</p>
+<p>
+Installing the built driver from the pre-announced RC branch in the
+system and making some every day's use until the release may be a good
+idea too.
+</p>
+
<h1 id="branch">Making a branchpoint</h1>
Now go to
<a href="https://bugs.freedesktop.org/editversions.cgi?action=add&product=Mesa" target="_parent">Bugzilla</a> and add the new Mesa version X.Y.
</p>
+
<p>
Check that there are no distribution breaking changes and revert them if needed.
For example: files being overwritten on install, etc. Happens extremely rarely -
we had only one case so far (see commit 2ced8eb136528914e1bf4e000dea06a9d53c7e04).

Patch that is nominated but yet to to merged in the patch queue/branch.

Patch is in the queue/branch and will feature in the next release.
Barring reported regressions or objections from developers.

<h3>Get latest source files</h3>
+
<p>
Ensure the latest code is available - both in your local master and the
relevant branch.
</p>
<h3>Perform basic testing</h3>
+
<p>
Most of the testing should already be done during the
<a href="#pickntest">cherry-pick</a> and
<a href="#prerelease">pre-announce</a> stages.
