existing workloads to fail or be rejected. We recommend that you test your systems thoroughly as part of your Netty upgrade.</p> <p>Two specific changes are worth calling out:</p> <p><strong>QUIC now explicitly requires <code>X509ExtendedTrustManager</code> when hostname verification is enabled.</strong> Previously, when configuring QUIC with an endpoint identification algorithm and an <code>X509TrustManager</code>, hostname verification would be silently skipped. This is now considered a misconfiguration and an exception will be thrown.</p> <p><strong>HTTP/2 header <em>value</em> validation is now enabled by default.</strong> HTTP/2 header <em>name</em> validation has always been enabled by default, with an option to disable it, but HTTP/2 header <em>value</em> validation has been disabled by default until now. Configuration options still exist to disable this, but validation of HTTP header names and values are now both opt-in by default rather than opt-out.</p> <h2>What's Changed</h2> <ul> <li>Use X509ExtendedTrustManager in SSLErrorTest by <a href="https://github.com/normanmaurer";><code>@normanmaurer</code></a> in <a href="https://redirect.github.com/netty/netty/pull/17221";>netty/netty#17221</a></li> <li>Update setup-testlens to v1.9.4 by <a href="https://github.com/marcphilipp";><code>@marcphilipp</code></a> in <a href="https://redirect.github.com/netty/netty/pull/17223";>netty/netty#17223</a></li> </ul> <!-- raw HTML omitted --> </blockquote> <p>...
