+# Pulse v4.31.0
+
+## What's Changed
+
+### Temperature monitoring over HTTPS
+- `pulse-sensor-proxy` now exposes an authenticated HTTPS endpoint per Proxmox host. Pulse stores each proxy’s URL + bearer token and always polls `https://node:8443/temps` before falling back to local sockets or SSH, eliminating the fragile “single proxy for every node” chain.
+- Installations auto-register via the new `/api/temperature-proxy/register` endpoint, generate 4096-bit certificates, enforce CIDR allowlists, and log every HTTP request through the proxy’s audit pipeline.
+- The backend temperature collector understands proxy URLs/tokens, respects strict timeouts, and publishes richer diagnostics so operators can see which node failed and why.
+
+### Installer, diagnostics, and UI updates
+- `scripts/install-sensor-proxy.sh` gained `--http-mode` / `--http-addr`, automatic TLS generation, rollback-on-failure, allowed subnet auto-population, and a comprehensive uninstall path that purges sockets, TLS secrets, and LXC bind mounts.
+- A new `Settings → Diagnostics → Temperature Proxy` table surfaces proxy health, registration status, and the errors returned by the HTTPS endpoint.
+- `scripts/tests/test-sensor-proxy-http.sh` exercises the HTTP installer path end-to-end inside Docker to prevent regressions.
+
+### Host agent refinements
+- Windows PowerShell installers/uninstallers now log verbosely, harden permissions, and clean up services more reliably.
+- Linux host-agent scripts aligned with the new diagnostics UX and scoped token workflow so onboarding is less error-prone.
+
+## Upgrade Notes
+
+Temperature monitoring will not work for remote nodes until every Proxmox host is reinstalled with the new HTTPS workflow. Follow these steps per host:
+
+```bash
+# 1. Remove any pre-v4.31.0 proxy install
+curl -fsSL https://raw.githubusercontent.com/rcourtman/Pulse/main/scripts/install-sensor-proxy.sh | \
+  sudo bash -s -- --uninstall --purge
+
+# 2. Install the HTTP-enabled proxy and register it with Pulse
+curl -fsSL https://raw.githubusercontent.com/rcourtman/Pulse/main/scripts/install-sensor-proxy.sh | \
+  sudo bash -s -- --standalone --http-mode --pulse-server https://your-pulse-host:7655
+```
+
+Only the Pulse server (or container host) needs network access to TCP/8443 on each node. After reinstalling, open **Settings → Diagnostics → Temperature Proxy** to confirm each node reports “HTTPS proxy healthy”. If not, grab the diagnostics entry or run:
+
+```bash
+curl -vk https://node.example:8443/health \
+  -H "Authorization: Bearer $(sudo cat /etc/pulse-sensor-proxy/.http-auth-token)"
+```
+
