<h2id="versioning">Versioning</h2>
<p>Minor version numbers (0.0.x) are used for changes that are API compatible. You should be able to upgrade between minor point releases without any other code changes.</p>
<p>Medium version numbers (0.x.0) may include API changes, in line with the <ahref="#deprecation-policy">deprecation policy</a>. You should read the release notes carefully before upgrading between medium point releases.</p>
<p>REST framework releases follow a formal deprecation policy, which is in line with <ahref="https://docs.djangoproject.com/en/dev/internals/release-process/#internal-release-deprecation-policy">Django's deprecation policy</a>.</p>
<p>The timeline for deprecation of a feature present in version 1.0 would work as follows:</p>
<ul>
<li>
<p>Version 1.1 would remain <strong>fully backwards compatible</strong> with 1.0, but would raise <code>PendingDeprecationWarning</code> warnings if you use the feature that are due to be deprecated. These warnings are <strong>silent by default</strong>, but can be explicitly enabled when you're ready to start migrating any required changes. For example if you start running your tests using <code>python -Wd manage.py test</code>, you'll be warned of any API changes you need to make.</p>
</li>
<li>
<p>Version 1.2 would escalate these warnings to <code>DeprecationWarning</code>, which is loud by default.</p>
</li>
<li>
<p>Version 1.3 would remove the deprecated bits of API entirely.</p>
</li>
</ul>
<p>Note that in line with Django's policy, any parts of the framework not mentioned in the documentation should generally be considered private API, and may be subject to change.</p>
