+
+## ‼️ Attention: Themerr-plex is back!
+
+After being archived, Themerr-plex has been revived with a major rewrite since the last stable release in August 2024.
+
+**Themerr-plex now runs as a standalone application alongside Plex Media Server. Upgrading from `v2024.813.13709` or earlier requires migration to the new application.** Installation, configuration, and Plex authentication have changed. ([#497](https://github.com/LizardByte/Themerr-plex/pull/497))
+
+## ⚠️ Breaking changes and migration notes
+
+- **Remove the old plug-in before starting the standalone application.** Stop Plex Media Server, remove the Themerr-plex bundle from its `Plug-Ins` directory, and restart Plex. Install the standalone release archive or Docker image, and keep Themerr-plex running to process library updates.
+- **Complete the new account setup.** On first launch, use the one-time setup link shown in the console to create your Themerr administrator account. The default web UI is available at `https://localhost:9494`; its locally generated certificate may trigger a browser warning.
+- **Reconnect Plex and configure your settings.** In **Servers**, select **Sign in with Plex**, then connect the servers you want to manage. Your Themerr administrator account protects the application; your Plex account authorizes server access. Review your processing, overwrite, and ignored-library settings in the new application.
+- **Use the modern Plex metadata agents.** Theme processing supports **Plex Movie** and **Plex Series** libraries. Legacy metadata agents are no longer supported.
+- **Check locked fields when migrating.** Older Themerr-plex versions may have left themes or collection metadata locked. Enable **Ignore locked fields** if you want Themerr to update those fields.
+- **Plex data-directory access is needed for cleanup.** Theme uploads use the Plex API. Removing older uploaded themes, posters, or artwork also requires access to the server’s Plex data directory. If that directory is unavailable, disable the three **Remove unused** settings.
+- **Docker requires persistent configuration and a token encryption key.** Persist `/config`, mount a private key file outside that volume, and set `THEMERR_PLEX_TOKEN_KEY_FILE`. Keep the same key when recreating the container.
+- **YouTube extraction has changed.** Themerr now uses `yt-dlp`, with Deno bundled in release archives. If YouTube requires sign-in, the **YouTube Cookies** setting accepts a JSON cookie export.
+
+See the [installation guide](https://docs.lizardbyte.dev/projects/themerr-plex/latest/about/installation.html), [setup and usage guide](https://docs.lizardbyte.dev/projects/themerr-plex/latest/about/usage.html), and [Docker instructions](https://docs.lizardbyte.dev/projects/themerr-plex/latest/about/docker.html).
+
+## ✨ Highlights
+
+- **A dedicated management interface.** Manage multiple Plex servers, inspect theme coverage, search and filter your libraries, and monitor scans and upload failures.
+- **Persistent theme playback.** Listen while navigating the application, with seeking, volume, shuffle, repeat, and supported system media controls. ([#594](https://github.com/LizardByte/Themerr-plex/pull/594))
+- **Better troubleshooting and customization.** Browse searchable logs with session history, choose automatic/light/dark appearance, and exclude libraries per server. ([#592](https://github.com/LizardByte/Themerr-plex/pull/592), [#593](https://github.com/LizardByte/Themerr-plex/pull/593), [#595](https://github.com/LizardByte/Themerr-plex/pull/595))
+- **Desktop notifications.** Receive configurable alerts for new releases and increased theme coverage. ([#596](https://github.com/LizardByte/Themerr-plex/pull/596))
+- **Broader installation choices.** Native x86-64 and ARM64 archives are available for Windows, Linux, and macOS, alongside Docker images.
