The official Weblate Docker container just received an important change. In case you are using it, you will probably have to adjust your configuration after upgrading.
The container is no longer executed as root, but as an unprivileged user. This makes it more secure and also compatible with some cloud providers such as OpenShift. However this brings its downsides as well; the exposed port had to change from the privileged one. This is design the container probably should have had from the beginning, but better to fix it later than never.
