Debian Python Policy
<br>Appendix C - Upgrade Procedure</h1>
<hr>
<p>
This section describes the procedure for the upgrade when the default python
version is changed in the <samp>unstable</samp> distribution, requiring
recompilation of many python-related packages.
</p>
<ol type="1" start="1" >
<li>
<p>
Selected pre-releases and release candidates of new Python versions are
uploaded to Experimental to support pre-transition work and testing.
</p>
</li>
</ol>
<ol type="1" start="2" >
<li>
<p>
Application and module maintainers make sourceful changes where needed to
prepare for the new Python version when needed.
</p>
</li>
</ol>
<ol type="1" start="3" >
<li>
<p>
Have a long and heated discussion.
</p>
</li>
</ol>
<ol type="1" start="4" >
<li>
<p>
The Debian Python maintainer and module/application maintainers discuss the
readiness for a new default Debian Python version and associated
packaging/policy changes. Once there is some consensus, the Python maintainer
announces the upgrade and uploads to Unstable.
</p>
</li>
</ol>
<ol type="1" start="5" >
<li>
<p>
Upload of the python core meta-packages <code>python</code>,
<code>python-dev</code>, <code>python-doc</code> and several
<code>python-<var>module</var></code>, depending on the new
<code>python<var>X</var>.<var>Y</var></code>,
<code>python<var>X</var>.<var>Y</var>-dev</code> and so on.
</p>
</li>
</ol>
<ol type="1" start="6" >
<li>
<p>
The release team schedules rebuilds for packages that may need it. Packages
that require additional manual work get updated and uploaded.
</p>
</li>
</ol>
