# Changelog (nightly branch)

Note: Breaking changes between versions are indicated by "💥".

- [Feature] Better support of Caddy as a load balancer in Kubernetes:
  - Make it possible to start/stop a selection of resources with ``tutor k8s start/stop [names...]``.
  - Make it easy to deploy an independent LoadBalancer by converting the caddy service to a ClusterIP when ``ENABLE_WEB_PROXY=false``.
  - Add a ``app.kubernetes.io/component: loadbalancer`` label to the LoadBalancer service.
  - Add ``app.kubernetes.io/name`` labels to all services.
  - Preserve the LoadBalancer service in ``tutor k8s stop`` commands.
  - Wait for the caddy deployment to be ready before running initialisation jobs.
- [Security] On Kubernetes, convert all NodePort services to ClusterIP to guarantee network isolation from outside the cluster.
- 💥[Improvement] Drop Python 3.5 compatibility.
- [Bugfix] Fix docker-compose project name in development on nightly branch.
- 💥[Bugfix] No longer track the Tutor version number in resource labels (and label selectors, which breaks the update of Deployment resources), but instead do so in resource annotations.
- [Bugfix] Make it possible for plugins to implement the "caddyfile" patch without relying on the "port" local variable.
- 💥[Improvement] Move the Open edX forum to a [dedicated plugin](https://github.com/overhangio/tutor-forum/) (#450).
- 💥[Improvement] Get rid of the "tutor-openedx" package, which is no longer supported.
- [Bugfix] Fix running Caddy container in k8s, which should always be the case even if `ENABLE_WEB_PROXY` is false.
- 💥[Improvement] Run all services as unprivileged containers, for better security. This has multiple consequences:
  - The "openedx-dev" image is now built with `tutor dev dc build lms`.
  - The "smtp" service now runs the "devture/exim-relay" Docker image, which is unprivileged. Also, the default SMTP port is now 8025.
- 💥[Feature] Get rid of the nginx container and service, which is now replaced by Caddy. this has the following consequences:
    - Patches "nginx-cms", "nginx-lms", "nginx-extra", "local-docker-compose-nginx-aliases" are replaced by "caddyfile-cms", "caddyfile-lms", "caddyfile", " local-docker-compose-caddy-aliases".
    - Patches "k8s-deployments-nginx-volume-mounts", "k8s-deployments-nginx-volumes" were obsolete and are removed.
    - The `NGINX_HTTP_PORT` setting is renamed to `CADDY_HTTP_PORT`.
