+## [v2.8.0] - 2026-08-11
+
+Rolls up **sso-manager-node v2.8.0**. Fixes found while auditing the v2.7.0
+multi-site work for gaps, plus the published docs staleness that same audit
+turned up.
+
+### sso-manager-node v2.8.0
+- Promotion no longer orphans the demoted old master's LDAP replication --
+  `/demote` now registers itself with the new master immediately instead of
+  being left with no way to ever get a real `ldapServerId` again.
+- The Directory's site slug and the multi-site replication identity are
+  unified -- previously unrelated values that happened to share a name.
+- LDAP replication status (real vs. advertised ServerID, a `stale` flag) and
+  per-spoke detail (not just an aggregate count) on the Multi-Site modal.
+
+### theta-suite docs
+- Fixed multiple stale/contradictory claims on the published site: the
+  no-inbound relay described as "designed but not automated" (shipped
+  earlier this session), `docs/sso/replication.md` never mentioning the new
+  LDAP MMR auto-config at all, and the homepage feature list only
+  describing the old manual N-way replication.
+
+## [v2.7.0] - 2026-08-11
+
+Rolls up **sso-manager-node v2.7.0**. Closes the last "operator hand-sets
+this" item on the multi-site TODO: OpenLDAP N-way multi-master replication
+now configures itself.
+
+### theta-suite orchestration
+- **`bootstrap/site-ldap-register.js`**: runs on every `setup.sh` invocation
+  (master and spoke), fetches this node's auto-assigned `LDAP_SERVER_ID` +
+  current peer list from sso-manager-node's new endpoints, and restarts
+  `sso-manager` only when the computed config actually changed.
+- `CFG_LDAP_MMR_MANUAL=true` skips the automatic step for a topology outside
+  this cluster the script can't derive on its own -- otherwise it always
+  runs (every fresh install starts as a master) and would overwrite
+  hand-set values.
+- `setup.env.example`'s old `#LDAP_SERVER_ID=1`/`#LDAP_REPLICATION_HOSTS=`
+  manual-config prompt is gone for the common case.
+
+### sso-manager-node v2.7.0
+- `SiteSpoke.ldapServerId` auto-assigned at registration (same pattern as
+  jump-host's mesh index); each site's LDAP URL derived from its
+  already-known HTTP(S) endpoint. New `GET /api/site/ldap-peers`
+  (spoke-facing) and `GET /directory-admin/ldap-replication-config`
+  (master-local). Verified against real running containers.
+
+## [v2.6.0] - 2026-08-11
+
+Rolls up **sso-manager-node v2.6.0** and **jump-host v2.1.1** (already
+current). Fixes several real bugs found on a live deployment: theta-agent
+never got its `server_url` written, `theta-agent update` 404'd because
+setup.sh installed a stale committed binary, the Directory's site slug and
+gateway count were both wrong, and duplicate group rows accumulated on
+repeated resource promotion.
+
+### theta-suite orchestration
+- **`server_url` now gets written into `/etc/theta42/agent.yml`.** setup.sh's
+  theta-agent install step `sed`'d in `join_key` but never touched
+  `server_url`, so it kept `agent.yml.example`'s literal placeholder forever.
+  Self-heals an already-installed `agent.yml` too (never touches
+  `join_key`/`auth_token`).
+- **`theta-agent update` no longer 404s.** setup.sh now downloads the current
+  release binary from GitHub instead of trusting one committed in the
+  theta-agent submodule checkout, which predated an upstream fix and could
+  never self-update out of the bug. Matches theta-agent's own `install.sh`.
+  The stale committed binaries were removed from the theta-agent repo.
+- **`SITE_SLUG` auto-derived from `CFG_SITE_NAME`.** Nothing ever set it
+  before, so a fresh master always showed the app's own literal
+  "site-default" fallback.
+- **`PROXY_INTERNAL_URL`/`JUMP_INTERNAL_URL` wired into `docker-compose.yml`.**
+  Both the no-inbound relay automation and the new real gateway-mesh count
+  existed in sso-manager-node's code but were completely unreachable in
+  every real deployment -- neither env var was ever actually set.
+- **`spoke.env.example`** -- a dedicated file for the join-a-cluster vars,
+  split out of `setup.env` for clarity (which still has every option).
+  Layered on top of `setup.env` when present. Also adds `CFG_PUBLIC_DOMAIN`
+  (documented in the spec but never wired into setup.sh before).
+
+### sso-manager-node v2.6.0
+- Fixed duplicate access/admin groups accumulating on repeated resource
+  promotion (three independent copies of the same missing-existence-check
+  bug).
+- `GET /api/directory-admin/resources` no longer runs a full LDAP group
+  self-heal fan-out on every list -- moved to write-time, with an explicit
+  `POST /resources/heal-groups` for backfill.
+- Recovers an nmap scan that completed successfully despite a benign stderr
+  warning nmap itself prints (`node-nmap` treated it as a fatal failure).
+- The Multi-Site modal's gateway count now queries jump-host's real mesh
+  registry instead of an unrelated WireGuard subsystem.

+you don't set these by hand.** The master assigns each spoke a unique
+`LDAP_SERVER_ID` at join time (the same way it assigns a WireGuard mesh
+index) and derives `LDAP_REPLICATION_HOSTS` from every site's already-known
+HTTPS endpoint (`ldaps://<same-host>:636`) -- `theta-suite`'s `bootstrap/
+site-ldap-register.js` applies it and re-checks on every `setup.sh` run,
+since the peer list grows as new spokes join, restarting `sso-manager` only
+when the computed config actually changed.
 
-**Site 1 (`setup.env` or `docker-compose.yml`)**
+**Known limitation**: the *master's* own `LDAP_REPLICATION_HOSTS` only gets
+recomputed when its `setup.sh` is re-run — there's no live push telling an
+already-running master about a spoke that joined five minutes ago. Re-run
+`setup.sh` on the master after bringing up a new spoke (or after promoting
+one to master) to pick up the current peer list. A spoke's own config, by
+contrast, is re-checked and applied on every `setup.sh` run there, which is
+the common/recurring event.
+
+### Manual configuration
+
+Have a topology outside a `theta-suite`-managed cluster (fully independent,
+always-writable sites, no master/spoke concept)? Set
+`CFG_LDAP_MMR_MANUAL=true` to skip the automatic path entirely and set the
+two variables directly -- without this, the automatic step runs on every
+deployment (every fresh install starts as a master) and will overwrite them.
+
+**Site 1**
 ```env
 LDAP_SERVER_ID=1
 LDAP_REPLICATION_HOSTS="ldaps://sso.site2.com:636 ldaps://sso.site3.com:636"
 ```

+**Site 3**
 ```env
 LDAP_SERVER_ID=3
 LDAP_REPLICATION_HOSTS="ldaps://sso.site1.com:636 ldaps://sso.site2.com:636"

-Once configured, the container's entrypoint will automatically load the `syncprov` module, enable `mirrormode`, and generate the necessary `syncrepl` blocks in `/etc/openldap/slapd.conf`.

 ## User Locations
 
 When creating or editing a user, you can specify their **Location (Site)**. This maps directly to the standard LDAP `l` (localityName) attribute, allowing you to track which physical site a user belongs to natively within the directory.
