# Upgrading

```bash
docker compose pull && docker compose up -d
```

The database migrates on start. Data in the volume stays. `docker compose restart` alone keeps the old image.

Pinned a version? Change the tag in `docker-compose.yml` first. All versions and their notes: [GitHub releases](https://github.com/baeroe/prevju/releases).

## Notes per version

### 0.3.1

* New MCP tool `get-compatibility`: agents check a draft against [What works](/what-works) before uploading. Connected MCP clients see it after a reconnect. Nothing to change on upgrade.

### 0.3

* MCP server and a new **MCP** page in the admin for tokens. Nothing to change on upgrade.

### 0.2.1

* Fixes assets loading as `http://` behind a reverse proxy.

### 0.2

* New admin UI. The admin moved from `/admin` to the root URL, old bookmarks to `/admin` stop working.
* The default host port in the example compose file is now `7738`. Existing setups keep their port.
