+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+## 2.0.0 - 2026-07-28
+
+### 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.

+
+## 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.
+
+## 1.5.2 - 2026-07-25
+
+### Fixed
+
+- Fixed player media upload sync so signed upload requests are verified after the request body has been parsed.
+
+## 1.5.1 - 2026-07-25
+
+### Fixed
+
+- Fixed the account page so it can save changes again.

+- Broader slide, template, playlist, RSS, and API source support, including richer region handling and background refresh processing.
+
+### Changed
+
+- Reworked the web admin app around a newer modular route and view layout, with shared helpers moving into `src/web/lib`, `src/web/pages`, and `src/web/views`.

+- Rebuilt RBAC around CRUD permissions and updated the admin screens for roles, users, and action gating.
+- Refactored the player onboarding flow, client-name handling, and runtime storage so screen identities persist more reliably across refreshes.
+- Tightened duplicate-name checks and other admin-side validation paths.
+
+### Fixed
+
+- Improved player fallback behavior when the database is unavailable.
+- Cleaned up player runtime and routing paths so screen lookups and live updates degrade more gracefully.

 ## Configuration
 
-The app reads its settings from environment variables.
+The app reads its settings from environment variables. The list below matches the provided `.env.example` file.
+
+### Compose and Shared Settings
+
+- `PULSE_SIGNAGE_IMAGE` - image tag used by the published Compose setup, default `git.lzstealth.com/lzstealth/pulse-signage:latest`
+- `PULSE_SIGNAGE_SHARED_SECRET` - shared secret used to sign player page API fetches and server-to-player requests; page tokens auto-renew while the page stays active and request signatures must be fresh; leave unset to keep the auth checks disabled for compatibility
 
 ### Database Connection
 
-- `DB_HOST` - MySQL host, default `127.0.0.1`
+- `DB_HOST` - MySQL host, default `mysql`
 - `DB_PORT` - MySQL port, default `3306`
-- `DB_NAME` - database name, default `signage`
-- `DB_USER` - database user, default `signage_user`
+- `DB_NAME` - database name, default `pulse-signage`
+- `DB_USER` - database user, default `pulse-signage`
 - `DB_PASSWORD` - database password, default `signage_password`
-
-### Web Admin App
-
-- `WEB_PORT` - admin app port, default `3000`
-- `PLAYER_INTERNAL_BASE_URL` - player address used by the server, default `http://player:3001`
-- `PLAYER_PUBLIC_BASE_URL` - player address shown in browser links, default `http://localhost:3001`
-- `UPLOAD_DIR` - storage location for uploaded files, default `./uploads`
+- `MYSQL_ROOT_PASSWORD` - root password for the bundled MySQL container, default `root_password`
 
 ### Player App
 
-- `PLAYER_PORT` - player port, default `3001`
+- `PLAYER_INTERNAL_BASE_URL` - internal player URL used by the web app, default `http://player:8081`
+- `PLAYER_PUBLIC_BASE_URL` - public player URL used by browser-facing links, default `http://localhost:8081`
 
-## Using Docker
+### Web App
 
-The recommended way to run the project is with Docker Compose.
+- `SESSION_MAX_AGE_DAYS` - admin session lifetime in days, default `14`
+- `DASHBOARD_REFRESH_INTERVAL_MS` - dashboard refresh interval in milliseconds, default `2000`
+- `DEFAULT_ADMIN_USERNAME` - username used for the initial admin account, default `admin`
+- `DEFAULT_ADMIN_NAME` - display name used for the initial admin account, default `Admin`
+- `DEFAULT_ADMIN_PASSWORD` - password used for the initial admin account, default `admin`
+- `PASSWORD_HASH_ITERATIONS` - password hash iteration count, default `310000`
 
-```bash
-npm run docker:up
-```
+## Docker Compose
 
-The main Compose file now uses the published Docker image and still reads values from the repository `.env` file. `DB_HOST` comes from that file for the app containers, so you can point the web UI and player at an external database host or change it to `mysql` if you want to use the bundled MySQL service.
+The repository includes a `docker-compose.yml` file that starts three services:
 
-If you only want to test the image build from the current checkout without using Compose, run:
+- `web` - the admin app exposed on container port `8080`
+- `player` - the signage player exposed on container port `8081`
+- `mysql` - the database on port `3306`
 
-```bash
-npm run docker:build
-```
+Change the published host ports in Docker Compose if you want different external ports; the app containers listen on `8080` and `8081` internally.
 
-To publish the Docker image to the Gitea container registry, push to `main` or create a `v*` tag. The workflow in [.gitea/workflows/docker-publish.yml](.gitea/workflows/docker-publish.yml) builds `git.lzstealth.com/LZStealth/pulse-signage` and pushes `latest`, `sha`, and tagged releases.
+By default, `web` and `player` use the published image from `git.lzstealth.com/lzstealth/pulse-signage:latest`. You can point both services at a specific release by setting `PULSE_SIGNAGE_IMAGE` to a tagged image such as `git.lzstealth.com/lzstealth/pulse-signage:v1.0.0`.
 
-This starts:
+The Compose file also defines a shared `media` volume for stored assets and a `mysql_data` volume for database persistence.
 
-- the web admin app on port `3000`
-- the player app on port `3001`
-- MySQL on port `3306`
-
-The web app and player app share the same uploaded media volume, so files uploaded in the admin UI are available to the player.
-
-If you want to stop the stack later, run `npm run docker:down`. To follow logs, run `npm run docker:logs`.
+In Docker, media storage is controlled by the `media` volume mount at `/app/media`.
+Outside Docker, the web app and player do not have to use the same upload location or even the same server, as long as each service can access its own configured media path.
 
 ## Important Notes
 
 - The web app must be able to reach the player through `PLAYER_INTERNAL_BASE_URL`.
 - When running in Docker, that value should point to the Docker service name, not `localhost`.
-- Uploaded media is stored separately from the application source, so make sure it is backed up if you are not using Docker volumes.
+- If `PULSE_SIGNAGE_SHARED_SECRET` is set, the web and player containers must use the same value, and any reverse proxy in front of the player must forward `/api/media/...` without rewriting the path.
+- Uploaded media is stored separately from the application source, so make sure it is backed up if you are not using Docker volumes.
+- The player page uses the browser Screen Wake Lock API when available, but kiosk mode and OS sleep settings still matter because the browser can deny or release the wake lock.

 ## Overview
 
-Player service base URL: `http://localhost:3001`
+Player service base URL: `http://localhost:8081`
 
-This document uses OpenAPI-style sections, but stays in plain markdown.
+This document covers the player HTTP surface only. The admin dashboard exposes its own routes for screen commands and onboarding management.
+
+Access note: most player endpoints are unauthenticated because they are meant to run inside a trusted deployment network. Anything that mutates state or writes files should be treated as internal-only unless you add your own auth layer in front of it.
+
+When `PULSE_SIGNAGE_SHARED_SECRET` is set, the player pages sign same-origin API fetches with `x-pulse-page-auth`, and the web app signs server-to-player requests with `x-pulse-request-timestamp` plus `x-pulse-request-signature`. Page tokens auto-renew before expiry while the page stays active, and signed server requests are only accepted when their timestamp is fresh. If the secret is unset, those checks stay disabled for compatibility.
