+# Changelog
+
+## 1.1.0 - 2026-05-21
+
+UI-focused release for the Django control panel.
+
+### Added
+
+- Dedicated list pages for runs, snapshots, schedules, purged snapshots, and changelog navigation.
+- Dashboard priority panels for required action, next scheduled work, recent activity, and storage pressure.
+- Dashboard host cards with clearer backup activity, snapshot health, next run, and retention status.
+- Lightweight live refresh for active run detail pages, including status, timing, controls, and rsync log output.
+- Lightweight live refresh for dashboard priority and host status sections.
+- Current-page navigation states for primary and system navigation.
+- Responsive dashboard behavior for narrower screens.
+
+### Changed
+
+- Reworked the primary navigation around day-to-day operator workflows and moved admin/system links out of the main path.
+- Simplified legacy-facing labels and removed source-of-truth wording that no longer applies to the Django-first model.
+- Improved run and snapshot detail pages with clearer links between backup runs, snapshots, logs, and review actions.
+- Improved dashboard spacing and card layouts to reduce cramped or overlapping text.
+- Documented the Django-template-first partial refresh pattern for future UI work.
+
+## 1.0.0 - 2026-05-21
+
+Initial stable release of the Django-first pobsync control panel.
+
+### Added
+
+- Django control panel for hosts, global settings, schedules, SSH credentials, snapshots, runs, self-checks, and logs.
+- Native systemd installer and updater for production backup servers.
+- SQLite by default, with optional MariaDB support.
+- Scheduler and worker services for queued manual backups and scheduled backups.
+- Manual backup, dry-run, cancellation, verbose rsync logging, and run detail views.
+- Snapshot discovery for existing backup directories and SQL-backed snapshot records.
+- SQL retention planning and apply flow with base snapshot protection and incomplete snapshot visibility.
+- Explicit cleanup flow for incomplete snapshots, separate from normal retention pruning.
+- Purged snapshot audit overview with reason, action source, operator, host, kind, path, and timestamp.
+- Dashboard and host pages with backup health, latest run/snapshot, next run, and storage/stat summaries.
+- Review resolution for failed/warning runs and incomplete snapshot tasks so operational warnings can be acknowledged.
+- Worker heartbeat metadata and stale running-run reconciliation for queued backup workers.
+- SSH key generation, upload, edit, guarded delete, known_hosts management, and per-host key selection.
+- In-app changelog page sourced from this changelog.
+- Restore guidance on snapshot detail pages.
+
+### Changed
+
+- Django and the database are now the source of truth for configuration.
+- Docker Compose is documented as development and disposable test tooling rather than the primary production path.
+- The `pobsync` console entrypoint is now a maintainer layer around Django management commands.
+- Scheduled pruning is evaluated by the pobsync scheduler service and recorded through Django, not host cron.
+- Retention and incomplete cleanup now preserve audit history even after source snapshot records are removed.
+
+### Removed
+
+- Legacy YAML config import/export workflow.
+- Public short aliases for configuration commands.
+- Obsolete global config storage fields.

+## Restoring Data
+
+pobsync treats restores as an explicit manual operation. The control panel shows restore guidance on each snapshot
+detail page, but it does not run restore commands for you yet. That is deliberate: restores should be inspected and
+tested before data is copied back into a live system.
+
+Each snapshot directory contains:
+
+```
+<snapshot>/data/  # backed-up filesystem contents
+<snapshot>/meta/  # metadata and rsync logs
+```
+
+Use the `data/` directory as the rsync source. Start with a dry run and restore to a staging path first:
+
+```
+rsync -aHAX --numeric-ids --info=progress2 --dry-run /backups/example.org/scheduled/<snapshot>/data/ /restore/example.org/
+rsync -aHAX --numeric-ids --info=progress2 /backups/example.org/scheduled/<snapshot>/data/ /restore/example.org/
+```
+
+After validating the staged files, copy the specific files or directories back to the target machine. For a full-host
+restore, use another dry run before writing to the remote root:
+
+```
+rsync -aHAX --numeric-ids --info=progress2 --dry-run /backups/example.org/scheduled/<snapshot>/data/ root@example.org:/
+```
+
+For most incidents, prefer a targeted restore instead of copying the whole snapshot. Keep paths relative to the
+snapshot's `data/` directory:
+
+```
+rsync -aHAX --numeric-ids --info=progress2 --dry-run /backups/example.org/scheduled/<snapshot>/data/etc/nginx/ /restore/example.org/etc/nginx/
+rsync -aHAX --numeric-ids --info=progress2 --dry-run /backups/example.org/scheduled/<snapshot>/data/home/example/site/public_html/index.php /restore/example.org/home/example/site/public_html/index.php
+```
+
+Snapshots may use hardlinks for files that are unchanged between backups. That saves disk space and is safe for normal
+restore copies, but do not edit files inside snapshot directories. Treat snapshots as read-only and copy data out with
+rsync.
+
 ## SSH Keys
 
 SSH keys can be managed from `/ssh-credentials/`. The recommended flow is to generate keys from Django or during the
-installer. pobsync stores the private key on disk under `POBSYNC_HOME`, keeps the public key visible in the UI, and lets

+The short `pobsync` aliases are limited to operational actions that are useful while debugging a running install.
+Configuration aliases are intentionally not public commands; use the Django UI or explicit management commands instead.
+
+## UI Refresh Pattern
+
+The control panel stays Django-template-first. Pages that need live status should expose a small server-rendered partial
+view and opt into refresh with `data-refresh-url` and `data-refresh-interval` on the container that should be replaced.
+The shared script in `base.html` polls only those explicit regions, skips refreshes while the browser tab is hidden, and
+lets the partial response turn polling off with the `X-Pobsync-Refresh-Active: false` header.
+
+Use this for operational status surfaces such as running backup details. Avoid refreshing form-heavy sections while an
+operator might be typing.

 The installer should print a short completion summary with the control panel URL, Self Check reminder, and service log

-## Migration Helpers
-
-Import existing legacy YAML configs:
-
-```
-python3 manage.py import_pobsync_configs --prefix /opt/pobsync
-```
-
-Export SQL config to legacy runtime YAML for inspection or one-off compatibility:

-```
-python3 manage.py export_pobsync_configs --prefix /opt/pobsync

-These commands are migration helpers, not the normal operating model. After import, review and continue operating from

+The updater is intentionally a small wrapper around the installer for routine production deploys. It should stay
+non-interactive, preserve the existing environment file, skip OS package installation, skip superuser creation, and still
+run the Django/runtime refresh steps needed after a code update.

+  --env-file PATH
+  --service-user USER
+  --service-group GROUP
