 # Changelog
 
+## 0.30.3 - 2026-05-17
+
+- Fixed container startup under `docker-compose` and custom `USER_UID`/`USER_GID` mappings by launching the web app with `python3 /app/app.py` directly instead of relying on the `./ani-cli-web` launcher file being executable inside the container.
+
 ## 0.30.2 - 2026-05-17
 
 - Added container runtime support for `USER_UID` and `USER_GID`, letting `ani-cli-web` run under a chosen numeric host user/group so files created in mounted folders are not owned by `root`.

@@ -124,6 +124,7 @@ Container defaults:
 
 - `ani-cli` is installed at `/usr/local/bin/ani-cli`.
 - `ani-cli-web` is cloned into `/app` and started from there.
+- Container startup now runs `python3 /app/app.py` directly, so it does not depend on the `ani-cli-web` launcher file having executable permissions inside the image.
 - Downloads are written to `/downloads`, so bind-mount `./downloads:/downloads`.
 - App state stays under `/app/.ani-cli-web`, so bind-mount `./.ani-cli-web:/app/.ani-cli-web`.
 - The image sets `ANI_CLI_WEB_HOST=0.0.0.0` and exposes port `8421`.
