WARNING: This is a breaking release, you will certainly need to read this & fix
your config to have a successful deployment! There has been a lot of churn on
this recipe due to the experimental nature of getting things up and running.
We're hoping things will stabilise soon. It's a lovely software after all and
users are enjoying using it.

- Additional login methods have been added e.g. Google (yep...). You now need
  to make a choice of which authentication you want to make. This can be done by
  using the usual `$AUTH_ENABLED=1` environment variable condition.

- If you were using the generic OpenID Connect authentication method (e.g.
  Keycloak, Authentik) then you will now need to use
  `COMPOSE_FILE=compose.yml:compose.oidc.yml` and provide the `OIDC_*`
  environment variables in your `.env` file. See the recipe `.env.sample` for
  more.

- We are no longer using a fork of Outline for the recipe (yay!). If you were
  using the old patched version, you'll have to deal with some migration issues.
  See https://git.coopcloud.tech/coop-cloud/outline#deleting-a-user-e-g-to-fix-sso-weirdness
  for more.

- Furthermore, following https://git.coopcloud.tech/coop-cloud/outline/issues/9, you will
  need to undeploy your stack and re-deploy as some of the services have been renamed to
  maintain naming conventions with other recipes.

There has been a lot of changes. Please add to this file if you see more
weirdness to help the rest of the Co-op Cloud Comrades.
