+## 0.35.2 — memory fix, health check options and Overview tiles
+
+- **Memory use restored:** with a large HOT cache, 0.35.1 used about 25% more memory than 0.35.0 (for example 1.1–1.2 GiB instead of about 800 MiB with a 600 MiB cache). The default build is back to the 0.35.0 memory profile. The faster alternative allocator is available as an optional build feature for servers with spare RAM; the Performance guide explains the trade-off with measurements.
+- **Health check port:** active TCP and HTTP health checks can probe a different port than the one receiving traffic, for example a status port 8079 for a backend serving on port 80. It can be set for a whole Vhost or per backend; host, TLS and address restrictions stay the same.
+- **Expected response text:** HTTP health checks can require a text fragment in the response body, so a status page that answers 200 while reporting a degraded state marks the backend as down.
+- **New Overview tiles:** healthy backends (with the names of failing ones), error share, requests rejected by limits and the nearest certificate expiry are shown on the Overview by default.
+- **Certificate expiry metrics:** Prometheus now exports the expiry date and remaining days of every installed certificate, including manually uploaded ones, for alerting.
+- **Safari:** the Overview no longer jumps when you scroll near the Backends table while live values refresh.
+- **Fixed:** network interface traffic below 1 KiB/s is shown as a whole number of bytes instead of a long decimal.
+- **Upgrade notes:** no configuration changes are required. Existing Overview layouts receive the new tiles at the end; hide or move them in the layout editor.

 ## 0.35.1 — performance, licensing and documentation
 
 - **Faster Web Server:** static files are read directly by the request instead of being handed to a background thread pool. Small and large files are served up to 1.8× faster with lower latency and CPU use.
-- **Faster reverse proxy and cache:** lighter request processing, header handling and traffic statistics collection. Proxied requests are about 12–19% faster and cache hits about 20% faster on the same hardware.
+- **Faster reverse proxy and cache:** lighter request processing, header handling and traffic statistics collection. Proxied requests are about 3–7% faster and cache hits about 11% faster on the same hardware.
 - **Vhost charts:** the per-Vhost request-rate chart no longer shows a false spike right after the page opens or when two refreshes arrive at the same moment.
 - **Performance guide:** new documentation page with the benchmark method, a comparison with a similarly configured Nginx and production tuning advice.
 - **About window:** redesigned with the project description, copyright, a GNU AGPL v3.0-or-later license summary and links to the project website, source code, built-in documentation and the full license text.
