2.5.0 / 2020-06-02
==================
**General**
* Use a session invalidation strategy inspired by Django. Newly generated user sessions will now include a HMAC of the user's password. When the user's password is changed by someone other than the user the previous HMACs will no longer be valid and the user will be logged out when they next attempt to perform an action.
* A user and team's place, and score are now cached and invalidated on score changes.
**API**
* Add `/api/v1/challenges?view=admin` to allow admin users to see all challenges regardless of their visibility state
* Add `/api/v1/users?view=admin` to allow admin users to see all users regardless of their hidden/banned state
* Add `/api/v1/teams?view=admin` to allow admin users to see all teams regardless of their hidden/banned state
* The scoreboard endpoints `/api/v1/scoreboard` & `/api/v1/scoreboard/top/[count]` should now be more performant because score and place for Users/Teams are now cached
**Deployment**
* `docker-compose` now provides a basic nginx configuration and deploys nginx on port 80
**Miscellaneous**
* The `get_config` and `get_page` config utilities now use SQLAlchemy Core instead of SQLAlchemy ORM for slight speedups
* Update Flask-Migrate to 2.5.3 and regenerate the migration environment. Fixes using `%` signs in database passwords.
Drop the default worker count in `docker-entrypoint.sh` because the default memory usage was higher than it needed to be. If you need more workers you can still increase the values and set a `SECRET_KEY` as before.
* Allow DATABASE_URL to contain custom MySQL ports for docker-entrypoint.sh
* Drop WORKERS count to 1 to avoid dealing with Flask-SocketIO sticky sessions
* Stop gunicorn from logging to `LOG_FOLDER` in docker without explicit opt-in
* Re-add the `LOG_FOLDER` envvar to docker-compose so we don't try to write to the read-only host
* Add `ACCESS_LOG` and `ERROR_LOG` envvars to docker to specify where gunicorn will log to
* docker-compose improvements
* Use gevent gunicorn workers
* Makes logs easier to access
* Customization of the logs location
* Improve secret key generation & only generate secret keys if one isn't defined (Closes#123)
* Install requirements required by plugins
CTFd creates the database instead of the docker-compose files which allows us to control encoding. Also adds a test for registering with a unicode team name.
