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.

* Improve `import_ctf()` reliability by closing all connections before dropping & recreating database
* Close database session in IP tracking code in failure situations to avoid potential dangling database connections
* Don't allow backups to be imported if they do not have a `db` folder
* Change `import_ctf()` process slightly to import built-in tables first and then plugin tables
* Handle exception where a regex Flag is invalid
**API**
* File deletion endpoint (`DELETE /api/v1/files/[file_id]`) will now correctly delete the associated file
**Plugins**
* Add `CTFd.plugins.get_plugin_names()` to get a list of available plugins

2.3.2 / 2020-03-15
==================
**General**
* Fix awards not being properly assigned to teams in `TEAMS_MODE`
**API**
* Set `/api/v1/statistics/users` route to be admins_only
* When POST'ing to `/api/v1/awards`, CTFd will look up a user's team ID if `team_id` is not specified
**Admin Panel**
* Adds a setting to registration visibility to allow for MLC registration while registration is disabled
* Fix setting theme color during the setup flow and from the Admin Panel
**Themes**
* Fixes users/admins being able to remove profile settings.
* Previously a bug prevented users from removing some profile settings. Now the `core` theme stores the initial value of inputs as a `data` attribute and checks for changes when updating data. This should be a temporary hack until a proper front-end framework is in place.
* Fix `ezToast()` issue that was keeping toast messages visible indefinitely
* Fix `modal-body` parameters in ezq.js for `ezAlert` and `ezQuery` and fix the progress bar for certain cases in `ezProgressBar`
* Use `authed()` function to check if user is authed in `base.html`. This fixes an issue where a page could look as if the user was logged in.
**Miscellaneous**

* Improve `Dockerfile` to run fewer commands and re-use the build cache

**General**
* During setup, admins can register their email address with the CTFd LLC newsletter for news and updates

* The `manage.py` script can now manipulate the CTFd Configs table via the `get_config` and `set_config` commands. (e.g. `python manage.py get_config ctf_theme` and `python manage.py set_config ctf_theme core`)
**Themes**
* Themes should now reference the `theme_header` and `theme_footer` configs instead of the `views.custom_css` endpoint to allow for user customizations. See the `base.html` file of the core theme.
**Plugins**
* Make `ezq` functions available to `CTFd.js` under `CTFd.ui.ezq`
**Miscellaneous**
* Python imports sorted with `isort` and import order enforced
