# 3.0.0a2 / 2020-07-09
**General**
* Accept additional profile fields during registration (affiliation, website, country)
* This does not add additional inputs. Themes or additional JavaScript can add the form inputs.
**Admin Panel**
* Redesign the challenge creation form to use a radio button with challenge type selection instead of a select input
**API**
* Admins can no longer ban themselves through `PATCH /api/v1/users/[user_id]`
**Themes**
* Spinner centering has been switched from a hard coded margin in CSS to flexbox CSS classes from Bootstrap
**Plugins**
* Revert plugin menu (`register_admin_plugin_menu_bar`, `register_user_page_menu_bar`) changes to 2.x code
**Miscellaneous**
* Fix issue with `Configs.ctf_name` returning incorrect value
* Add prerender step back into challenges.js
* Better handling of missing challenge types. Missing challenge types no longer bring down all other challenges.
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
2.2.0 / 2019-12-22
==================
## Notice
2.2.0 focuses on updating the front end of CTFd to use more modern programming practices and changes some aspects of core CTFd design. If your current installation is using a custom theme or custom plugin with ***any*** kind of JavaScript, it is likely that you will need to upgrade that theme/plugin to be useable with v2.2.0.

**API**

**Admin Panel**
* Admins can now user a color input box to specify a theme color which is injected as part of the CSS configuration. Theme developers can use this CSS value to change colors and styles accordingly.
* Challenge updates will now alert you if the challenge doesn't have a flag
* Challenge entry now allows you to upload files and enter simple flags from the initial challenge creation page
**Themes**
* Significant JavaScript and CSS rewrite to use ES6, Webpack, yarn, and babel
* Theme asset specially generated URLs
* Static theme assets are now loaded with either .dev.extension or .min.extension depending on production or development (i.e. debug server)

* Use `defer` for script tags to not block page rendering
* Only show the MajorLeagueCyber button if configured in configuration
* The admin panel now links to https://help.ctfd.io/ in the top right

**Plugins**

**Miscellaneous**
* `CTFd.utils.email.sendmail()` now allows the caller to specify subject as an argument
* The subject allows for injecting custom variable via the new `CTFd.utils.formatters.safe_format()` function
* Admin user information is now error checked during setup
* Added yarn to the toolchain and the yarn dev, yarn build, yarn verify, and yarn clean scripts
* Prevent old CTFd imports from being imported
