+## 0.32.3 -> 0.32.4 Preserve Host and Dashboard gutters
+
+No SQL schema, saved vhost JSON, account preferences or widget IDs change.
+`preserve_host: true` now works with `http1`, `auto`, `http2` and `h2` instead of
+being rejected for the latter three. If an HTTPS backend is addressed by IP but
+serves multiple vhosts, retaining the visitor Host also sets HTTP/2 `:authority`
+to the public host, while TCP/DNS use the configured URL and optional
+`tls_server_name` sets SNI/certificate identity. Keep a separate
+`health_check.host` for HTTP probes that require the vhost name. The debugging
+H1 preset remains optional, and original Overview widget preferences survive.
+Check TLS verification, hostname/certificate coverage and Angie handling on a
+real staging instance before deployment; the Rust compiler acceptance gate
+is still open.
