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.
2.3.0 / 2020-02-17
==================
**General**
* During setup, admins can register their email address with the CTFd LLC newsletter for news and updates
* Fix editting hints from the admin panel
* Allow admins to insert HTML code directly into the header and footer (end of body tag) of pages. This replaces and supercedes the custom CSS feature.
* The `views.custom_css` route has been removed.
* Admins can now customize the content of outgoing emails and inject certain variables into email content.
* 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
* Black formatter running on a majority of Python code
* Adopting a challenge type layout from deckar01
* Move standard challenge modals into the plugin
* Migration to change challenge type id to a string
* Travis testing now builds with MySQL, SQLite, and Postgres
* Rework get_standings to use the row ID instead of the saved time because of differences in database time precision
* Switching to Flask-Migrate to create tables/database. Adding Hints & Unlocks.
