-# v1.13.2
+## v1.35.0
+- feat: **permission entries can be edited.** The Permissions page only offered Delete, so changing a role or scope meant removing the grant and re-adding it from memory. New `PUT /api/permission/:id` plus an Edit modal pre-filled from the record.
+- fix: a permission's id is derived from (subjectType, subject, scope, domain), so changing any of those is a *different* record, not an update. The endpoint creates the new grant and removes the superseded one in that order, so an edit can never leave the old grant behind still conferring access.
+
+## v1.34.0
+- feat: the per-host SSO **Allowed groups** field now autocompletes from the SSO directory's groups. Suggestions previously came only from local groups, permission subjects and `conf.auth` maps — none of which can match an SSO-gated host, because its allow-list is checked against the `groups` claim the SSO issues. New `conf.sso` block (`url` + read-only `apiToken`, minted by theta-suite's bootstrap); results are cached for 5 minutes and the endpoint degrades silently to the old local-only list when unset.
+- fix: the SSO group lookup authenticates with `Authorization: Bearer <token>`, not the `auth-token` header — the latter is for browser session UUIDs and would be rejected for a minted API token.
+- docs: `docs/concepts-hosts.md` gains a "Putting a host behind single sign-on" section covering the per-host `/__proxy_auth` flow, the wildcard redirect URI the IdP must allow, and where group suggestions come from.
+- docs: `secrets.js.example` documents the new `sso` block.
+
+## v1.33.0
+- feat: Add SSO-style error page (404/500) for browser navigation instead of a bare JSON/text response
+- feat: DNS page is now admin-only (hidden from non-admins; API already admin-gated)
+- feat: navbar — username no longer underlined; only the active link is bold + underlined
+
+## v1.13.3
+- fix: remove missing DEPLOYMENT.md and docs/ from Docker build context
+
+## v1.13.2
 - chore: Update CI pipeline integration

 wildcard available to reuse — including the wildcard's own bare base
 domain (e.g. `example.com` itself, not just `something.example.com`).
 
+## Putting a host behind single sign-on
+
+Each host can be gated on its own, independently of the proxy's management UI.
+On the host's **Auth** tab pick **Single sign-on (SSO)** and, optionally, fill in
+the **Allowed users** / **Allowed groups** lists. Empty lists mean any
+authenticated user is allowed; otherwise the identity must match one of them.
+
+The proxy runs the OIDC flow itself at `/__proxy_auth` on the protected host and
+keeps a Redis-backed session in a `__proxy_sso` cookie, so the app behind it
+needs no changes.
+
+**The IdP must allow the per-host callback.** Each protected host calls back to
+`https://<that-host>/__proxy_auth/callback`, which is a different URL for every
+host, all against the proxy's one OAuth client. Register a wildcard redirect URI
+on that client — the SSO Manager supports `*` (one label) and `**` (any number):
+
+```
+https://**.example.com/__proxy_auth/callback
+https://example.com/__proxy_auth/callback
+```
+
+theta-suite's bootstrap registers both automatically, and backfills them onto an
+existing client. Without them, switching a host to SSO fails at the IdP with
+`400 redirect_uri is not registered for this client`.
+
+**Group suggestions come from the SSO.** The Allowed groups field autocompletes
+from the SSO directory's groups when `sso.url` and `sso.apiToken` are set in the
+proxy's config (theta-suite's bootstrap mints that read-only token). Without it
+the field can only suggest the proxy's local groups, which for an SSO-gated host
+are rarely the ones you want — the allow-list is matched against the `groups`
+claim in the SSO's token, so only SSO groups can ever match.
+
 ## Load Balancing
 
 If you have multiple servers running the same application, you can load balance traffic across them. When editing a host, you can specify **Additional Targets** (one `IP:port` per line). The proxy will automatically distribute incoming requests across your primary target and all additional targets using a round-robin strategy, providing simple high availability and load distribution without extra configuration.
