Add personal Unix group member management

 ## [Unreleased]
 
+## [1.1.9] - 2026-07-17
+
+### Added
+- Every account's personal Unix group (its primary GID holder) can now have supplementary members managed from the account's profile page ("Members of `<uid>`'s group", admin-only) — e.g. to share write access to files owned by that group. Uses the standard `memberUid` attribute (RFC 2307 `posixGroup`).
+
+## [1.1.8] - 2026-07-17
+
+### Added
+- Group membership is now editable directly from a user's profile page ("My groups" -- add via a group-name picker, remove with a button per row), instead of only from each group's own card on the Groups page. Admin-only, using the existing per-group member add/remove endpoints.
+
+### Fixed
+- The Edit Profile form's Mobile Phone field had a stray `validate=":9"` making it effectively required (submission was blocked with "Please fix the form errors" if left blank) -- it was always meant to be optional, matching the "Add user" form. Removed.
+- A service account's profile always showed `Name: Service Account` -- every service account has the same literal filler given/last name (a schema-satisfying placeholder, not meant to be shown), making them indistinguishable by name. The Name line is now hidden for service accounts.
+- The Users page's Service Accounts tab, and a freshly-created service account's own profile, could appear empty/not-a-service-account for up to 5 minutes right after creation. Creating a user caches it via `User.get()` *before* the route handler marks it as a service account (group membership), so the cached copy had `isServiceAccount` stuck wrong until the cache TTL expired. Now cleared and re-fetched immediately after marking.
+- A user belonging to exactly one LDAP group had their `memberOf` attribute returned as a bare string instead of a one-element array (ldapts's normal behavior for single-valued attributes) -- client-side permission checks (`for(let group of user.memberOf)`) would then iterate the DN character-by-character instead of once, causing pages gated on that group (e.g. Groups) to incorrectly show "You do not have permission to be here." Normalized `memberOf` to always be an array, same fix already applied to `manager`.

+### Personal groups
+
+Every user (person or service account) also gets a **personal Unix group**
+at creation — `cn=<uid>,ou=groups,<base>`, `objectClass: posixGroup` (RFC
+2307), holding just `cn` and `gidNumber` (the user's primary GID). This is a
+different schema than the `groupOfNames` groups above — its membership
+attribute is `memberUid` (a bare username, not a DN), and unlike
+`groupOfNames` it's valid with zero members. It's excluded from the
+`/groups` page (which filters on `objectClass=groupOfNames`) and managed
+instead from the owning user's own profile page ("Members of `<uid>`'s
+group", admin-only) — add other accounts as supplementary members, e.g. to
+share write access to files owned by this group.

 The SSO requires three groups (seeded automatically by the entrypoint /
 `install.sh`):
