<h2>v4.19.0</h2>
<!-- raw HTML omitted -->
<ul>
<li>Importing the <code>Validator</code> protocol directly from the
package root is deprecated. Import it from
<code>jsonschema.protocols.Validator</code> instead.</li>
<li>Automatic retrieval of remote references (which is still deprecated)
now properly succeeds even if the retrieved resource does not declare
which version of JSON Schema it uses. Such resources are assumed to be
2020-12 schemas. This more closely matches the
pre-<code>referencing</code> library behavior.</li>
