 ## [Unreleased]
 
+## [1.1.0] - 2026-03-13
+
+### Added
+- **Registration toggle** – New global setting to disable direct registration (`/register`). When disabled, visitors are redirected to sign-in and the register link is hidden; join form remains available.
+- **Configurable SMTP in global settings** – SMTP host, port, user, password, and TLS options configurable via Admin → Global Settings. Test-email action to verify delivery. Join confirmation and other transactional emails use this configuration.
+- **Theme and language selector on unauthenticated pages** – Sign-in and join pages now offer theme (light/dark) and locale (e.g. German/English) controls in the header.
+- **Duplicate-email handling for join form** – If an applicant’s email is already a member or already has a pending join request, the system sends a clarifying email (already-member or already-pending) and shows the same success message (anti-enumeration).
+- **Reviewed-by display for join requests** – Approval UI shows who reviewed a request via a dedicated display field, without loading the User record.
+- **Improved field order and seeds for join request approval** – Approval screen field order improved; seed data updated for join-form and approval flows.
+- **Tests for SMTP mailer configuration** – Tests for SMTP config and for join confirmation email delivery failure (domain and LiveView).
+
+### Changed
+- **SMTP settings layout** – SMTP options reordered and grouped in global settings for clearer configuration.
+- **Join confirmation mail** – Uses configurable SMTP from settings; on delivery failure the join form shows an error and no success message.
+- **i18n** – Gettext catalogs updated for new and changed strings.
+
+### Fixed
+- **Login page translation** – Corrected translation/locale handling on the sign-in page.
