 # Changelog
 
+## 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`.
+- Updated the Docker and Compose documentation to show how to pass host UID/GID values into the container.
+
 ## 0.30.1 - 2026-05-17
 
 - Added a `docker-compose.yaml` file that builds the bundled Docker image, mounts `./downloads` and `./.ani-cli-web`, and exposes the ani-cli git remotes, branch, and startup flags through Compose environment defaults.
