 <p>Version 4.52 introduces a queuing system for early tracking events in Single Page Applications (SPAs), a <code>nonblocking_tags</code> setting to improve Interaction to Next Paint (INP) scores, enhanced session counting for first-party setups, and performance optimizations.</p>

+<li><strong>Session counting for first-party, reverse proxy and self-hosted setups:</strong> First-party and reverse-proxy customers should remove any previous custom session counting logic to avoid duplicate sessions. For self-hosted setups, contact Tealium support to deactivate your billing requests.</li>
