<h2>10.1. About the checklist<a class="headerlink" href="#about-the-checklist" title="Permalink to this headline">¶</a></h2>
The checklist below has been created to simplify the upgrading process
of old packages. This list is not official or normative. It only
provides an indication of what has changed and whether you are likely to
need to make changes to your package in light of this. If you have
doubts about a certain topic, if you need more details, or if you think
some other package does not comply with policy, please refer to the
Policy Manual itself.
All of the changes from version 3.0.0 onwards indicate which section of
the Policy Manual discusses the issue. The section numbering should
still be accurate for changes back to the 2.5.0 release. Before that
point, the sections listed here probably no longer correspond to
sections in the modern Policy Manual.
Here is how the check list works: Check which policy version your
package was checked against last (indicated in the <code class="docutils literal notranslate">Standards-Version</code>
field of the source package). Then move upwards until the top and check
which of the items on the list might concern your package. Note which
sections of policy discuss this, and then check out the Policy Manual
for details. Once you’ve made all necessary changes to match the current
rules, update the value of <code class="docutils literal notranslate">Standards-Version</code> to the current Policy
Manual version.
If an item in the list is followed by the name of a Lintian tag in
square brackets, it indicates that the policy requirement is covered
by that Lintian tag. The lack of such an annotation does not mean
that no Lintian tag exists to cover the requirement. Our coverage of
these annotations is quite incomplete, and patches to this checklist
are very welcome.
The sections in this checklist match the values for the
<code class="docutils literal notranslate">Standards-Version</code> control field in omitting the minor patch version,
except in the two anomalous historical cases where normative
requirements were changed in a minor patch release.

Released July, 2003.
Restructuring caused shifts in section numbers and bumping of the
minor version number.
Many packaging manual appendices that were integrated into policy
sections are now empty, and replaced with links to the Policy. In
particular, the appendices that included the list of control fields
were updated (new fields like Closes, Changed-By were added) and the
list of fields for each of control, .changes and .dsc files is now
in Policy, and they’re marked mandatory, recommended or optional
based on the current practice and the behavior of the deb-building
tool-chain.
Elimination of needlessly deep section levels, primarily in the
chapter Debian Archive, from which two new chapters were split out,
Binary packages and Source packages. What remained was reordered
properly, that is, some sects became sects etc.
Several sections that were redundant, crufty or simply not designed
with any sort of vision, were rearranged according to the formula
that everything should be either in the same place or properly
interlinked. Some things remained split up between different
chapters when they talked about different aspects of files: their
content, their syntax, and their placement in the file system. In
particular, see the new sections about changelog files.
