 - The `traefik` integration now mounts config to `/data` instead of the path `/acme.json`, fixing permissions issues under certain architectures. To take advantage of the new functionality, the traefik container should be stopped (via `dokku traefik:stop`) and then started (via `dokku traefik:start`).
 - Users no longer need to clear the `source-image` git property when transitioning from image-based deploys (`git:from-image` and `git:load-image`) to other deployment methods (git push, `git:from-archive`, `git:sync`).
 - For deploys via the `git:from-image` and `git:load-image` commands, the `CHECKS` file is now extracted from the configured `WORKDIR` property of the image. For all other deploys - git push, `git:from-archive`, `git:sync` - will have the `CHECKS` extracted directly from the source code. The filename in both cases is `CHECKS` and cannot be modified.
+- The environment variable `DOKKU_PROXY_PORT_MAP` has been migrated to the properties system. Direct changes to the value will be ignored, and users should interact with port maps via the `ports` plugin.
