			==== Client-side TLS 1.3 and post-handshake authentication ====

			Janus client connections (for example, <var class="term">$SOCK</var>-based clients
			and Janus Web Server outbound HTTPS requests) now negotiate and complete a full
			TLS 1.3 handshake as the client, including X25519 key exchange, the HKDF-based
			key schedule, and RSA-PSS certificate verification of the server.

			Client certificate authentication is supported both during the initial handshake
			and after it completes. When a TLS 1.3 server sends a post-handshake
			<code>CertificateRequest</code> (RFC 8446 Section 4.6.2) — for example, when a
			server application requests a client certificate on a connection that did not
			originally require one — the Janus client automatically responds with its
			<code>Certificate</code>, <code>CertificateVerify</code>, and <code>Finished</code>
			messages, allowing the authenticated request to proceed without interrupting the
			connection.

			No application changes are required. Post-handshake authentication is used
			automatically when a server requests it and a client certificate is available for
			the port.

			===Hardware-accelerated deflate/inflate compression===
			The SOUL compression functions (<var>Deflate</var>, <var>Inflate</var>, <var>Gzip</var>, <var>Gunzip</var>, <var>Zip</var>, and <var>Unzip</var>) now exploit the IBM z15 (and above) DFLTCC (Deflate Conversion Call) hardware instruction when available. This provides significant performance improvement for compression and decompression of longstrings without any application code changes.

			Hardware acceleration is used automatically when the processor supports it. On processors without DFLTCC support, the existing software implementation continues to be used transparently.

			The DFLTCC instruction handles both the deflate (compress) and inflate (expand) operations natively in hardware, including CRC-32 computation, providing throughput improvements that scale with data size.

			===TLS 1.3 support===
			Janus SSL ports now support TLS 1.3 (RFC 8446) for both client and server connections. TLS 1.3 provides improved security and performance over TLS 1.2, including a simplified handshake with fewer round trips, and the removal of legacy features such as renegotiation.

			The following TLS 1.3 cipher suites are supported:
			<ul>
			<li><code>TLS_AES_128_GCM_SHA256</code></li>
			<li><code>TLS_AES_256_GCM_SHA384</code></li>
			</ul>

			Key exchange is performed using X25519 (Curve25519 Elliptic Curve Diffie-Hellman, per RFC 7748). Certificate authentication uses RSA-PSS signatures.

			Key derivation uses the HKDF-based key schedule defined in RFC 8446, replacing the PRF-based approach of earlier TLS versions.

			TLS 1.3 is enabled by default on ports that allow TLS 1.2. To restrict a port to earlier protocol versions, use the existing <var>SSLVERSION</var> parameter on the <var>[[JANUS DEFINE]]</var> command.
