 # Changelog
 
+## 0.1.0.0048 — 2026-07-15
+
+### Fixed
+- CSV import: loading spinner with "Importing..." message during upload
+- CSV import: better error display and proper modal close after completion
+- Admin panel: Import modal shows results and allows closing on success/failure
+
+## 0.1.0.0046 — 2026-07-11
+
+### Added
+- CSV bulk user import in Access tab — download template, fill data, upload
+- `/api/templates/users.csv` — sample CSV template download
+- `/api/users/import` — CSV import handler that parses and creates users via authelia-api
+
+## 0.1.0.0045 — 2026-07-11
+
+### Changed
+- MFA enforcement: after saving email in settings, if TOTP is not enabled, a blocking overlay forces the user to set up two-factor on the Authelia portal before proceeding
+
+## 0.1.0.0044 — 2026-07-11
+
+### Added
+- MFA/TOTP check on user settings page — shows setup prompt if no authenticator is configured
+- `/api/user/mfa-status` endpoint — checks Authelia for TOTP enrollment status
+
+## 0.1.0.0043 — 2026-07-11
+
+### Added
+- Edit user button in Access tab — admin can change email and groups (delete + recreate approach)
+- Edit user modal with email, groups fields, and new password display
+
+## 0.1.0.0039 — 2026-07-11
+
+### Changed
+- Modernized Authelia config format (fixes all deprecation warnings):
+  - `server.address: tcp://0.0.0.0:9091` (replaces `host` + `port`)
+  - `identity_validation.reset_password.jwt_secret` (replaces `jwt_secret`)
+  - `notifier.smtp.address: submission://...` (replaces `host` + `port`)
+  - `authentication_backend.file.watch: true` (auto-reload on user changes)
+  - `session.remember_me` (replaces `remember_me_duration`)
+
 ## 0.1.0.0038 — 2026-07-11
