-## Unreleased
+## 2.0.0 - 2026-07-28
 
-- No unreleased changes recorded yet.
+### Breaking Changes
+
+- Breaking database schema changes were introduced in this release; existing databases may require migration or recreation before upgrading.
+
+### Added
+
+- Broader player and admin release coverage across onboarding, playlist playback, background task handling, and media-region support.
+
+### Changed
+
+- The database bootstrap and migration flow were reorganized, with shared DB helpers split out to support the newer schema layout.
+- Admin and signage views were updated around the newer list, playlist, and RBAC behavior, including playlist scheduling and screen/client actions.
+- Player runtime, onboarding, and region rendering were tightened so HTML, image, RSS, RTMP, text, video, and webpage regions follow the newer playback flow.
+- Background task, upload sync, and data-source refresh handling were refined across the web app and startup paths.
+- Docker, environment, README, and websocket/api documentation were refreshed to match the current release structure.
+
+### Fixed
+
+- Client name checks, playlist editing, and slide/media synchronization paths were adjusted to better preserve existing references during admin and player updates.
+
+## 1.5.16 - 2026-07-26
+
+### Added
+
+- Background task handling was split into dedicated handler and scheduling modules, with startup data-source refreshes and unused-upload cleanup wired through the shared setup flow.
+
+### Changed
+
+- The admin shell, shared theme, and toast presentation were refreshed to match the newer layout and notification styling.
+- Playlist scheduling now handles video-duration toggles and already-assigned slides more clearly in the picker and editor UI.
+- RBAC and settings views were updated to align with the revised admin layout and shared table behavior.
+
+### Fixed
+
+- Template and slide thumbnail refreshes now run through the background task queue so template-wide thumbnail regeneration stays consistent.
+
+## 1.5.15 - 2026-07-26
+
+### Changed
+
+- Player slide transitions now start and pause video playback around the fade window so video regions stay aligned with the slide boundary.
+- Dashboard action cards now use a three-column grid on wider layouts.
+
+### Fixed
+
+- Slide video duration probes now preserve sub-second precision instead of rounding to whole seconds.
+
+## 1.5.14 - 2026-07-26
+
+### Fixed
+
+- Dashboard client action icons now render valid Bootstrap Icon classes without duplicating the `bi-` prefix.
+
+## 1.5.13 - 2026-07-26
+
+### Added
+
+- Shared table helpers for pagination, search, and sorting across the admin and signage views.
+
+### Changed
+
+- Refreshed the shared admin shell and moved common UI behavior into shared layout and helper modules.
+- Reworked dashboard, background tasks, RBAC, and signage list pages to use the newer shared table and state flow.
+- Updated the admin and player branding assets and tightened the page scripts around the new layout structure.
+
+## 1.5.12 - 2026-07-26
+
+### Changed
+
+- Shared web UI helpers are now loaded once in the admin shell and reused across the dashboard, admin, and template editor.
+- Template lists now show slide counts, and the template editor tracks which regions are already in use.
+
+### Fixed
+
+- Template editing now blocks removal of regions that are still referenced by slides.
+
+## 1.5.11 - 2026-07-26
+
+### Added
+
+- Video regions are now supported end to end, including player rendering, admin editing, playlist scheduling, and player sync.
+
+### Changed
+
+- The slide, template, and playlist flows were updated so video content can be created, configured, and scheduled alongside existing region types.
+- Player rendering and related media handling now recognize the new video region implementation.
+
+### Fixed
+
+- Region and upload handling were adjusted so video media syncs cleanly through the player and web admin paths.
+
+## 1.5.10 - 2026-07-26
+
+### Added
+
+- Scheduled background tasks now have their own settings page, separate permission gate, and manual run action alongside the main queue view.
+- The slide editor now includes a refreshed preview/sidebar layout and a cropper-based image upload flow.
+
+### Changed
+
+- Background task and admin list views now use richer pagination and filtering so queue state, task sources, and recurring jobs stay easier to navigate.
+- The admin shell and shared styling were refreshed to support the updated settings pages, slide editor layout, and task table presentation.
+
+### Fixed
+
+- Upload sync and slide thumbnail refresh handling were tightened so slide changes queue follow-up work more reliably.
+
+## 1.5.9 - 2026-07-26
+
+### Fixed
+
+- User creation now keeps the role checkboxes inside the add-user form so selected roles are submitted correctly.
+
+## 1.5.8 - 2026-07-25
+
+### Fixed
+
+- Upload removal requests now authenticate correctly when a deployed player parses a bodyless `DELETE` request as an empty object, which could cause 401s for newly uploaded images.
+
+## 1.5.6 - 2026-07-25
+
+### Changed
+
+- Playlist slide picker now uses a button to reveal already added slides, while still defaulting to showing only available slides.
+- Already-added slides in the picker are now labeled and visually muted to make them easier to spot.
+
+### Fixed
+
+- Thumbnails in slide and playlist tables now follow the slide canvas ratio and cap at 5.5rem tall.
+- Thumbnail-only table columns are no longer sortable.
+
+## 1.5.5 - 2026-07-25
+
+### Fixed
+
+- Fixed a migration gap that could leave `slides.thumbnail_path` missing on upgraded databases.
+
+## 1.5.4 - 2026-07-25
+
+### Added
+
+- Cropper.js has been added to aid with image uploading.
+
+### Changed
+
+- Upgraded Multer to 2.x to remove the deprecated 1.x dependency warning.
+- Tightened a few admin UI details, including slide editor and RBAC list spacing/typography adjustments.
+
+## 1.5.3 - 2026-07-25
+
+### Added
+
+- A modal-based slide picker for playlist editing with search, multi-select, and slide thumbnails.
+- Reusable modal and table-pagination helpers for the admin UI.
+- Slide thumbnail previews in playlist schedules, with image fallbacks when a thumbnail is missing.
+
+### Changed
+
+- RTMP playback now probes session readiness more aggressively and retries startup before surfacing failures.
+- Playlist editing now includes richer scheduling controls, live slide counts, and support for skipping unavailable RTMP slides.
+- Admin lists and background task pages now preserve filter and pagination state during AJAX navigation.
+- Shared admin shell styling and helpers were refreshed to support the newer list, modal, and pagination UI.
+
+### Fixed
+
+- Player upload sync and route handling now degrade more gracefully when backend services are unavailable.
+- RTMP and playlist playback now recover more cleanly when a stream fails to initialize or respond in time.

+- The schema is initialized with `CREATE TABLE IF NOT EXISTS`, so new installs can start from an empty database.
+- `src/db/index.js` also seeds default permissions and the default administrator role.
+- The migration module stays in place for future releases, but this version treats the current schema as the install baseline.
