2.4.0 / 2020-05-04
==================
**General**
* Cache user and team attributes and use those perform certain page operations intead of going to the database for data
* After modifying the user/team attributes you should call the appropriate cache clearing function (clear_user_session/clear_team_session)
* Cache user IPs for the last hour to avoid hitting the database on every authenticated page view
* Update the user IP's last seen value at least every hour or on every non-GET request
* Replace `flask_restplus` with `flask_restx`
* Remove `datafreeze`, `normality`, and `banal` dependencies in favor of in-repo solutions to exporting database
**Admin Panel**
* Add bulk selection and deletion for Users, Teams, Scoreboard, Challenges, Submissions
* Make some Admin tables sortable by table headers
* Create a score distribution graph in the statistics page
* Make instance reset more granular to allow for choosing to reset Accounts, Submissions, Challenges, Pages, and/or Notificatoins
* Properly update challenge visibility after updating challenge
* Show total possible points in Statistics page
* Add searching for Users, Teams, Challenges, Submissions
* Move User IP addresses into a modal
* Move Team IP addresses into a modal
* Show User website in a user page button
* Show Team website in a team page button
* Make the Pages editor use proper HTML syntax highlighting
* Theme header and footer editors now use CodeMirror
* Make default CodeMirror font-size 12px
* Stop storing last action via location hash and switch to using sessionStorage
**Themes**
* Make page selection a select and option instead of having a lot of page links
* Add the JSEnum class to create constants that can be accessed from webpack. Generate constants with `python manage.py build jsenums`
* Add the JinjaEnum class to inject constants into the Jinja environment to access from themes
* Update jQuery to 3.5.0 to resolve potential security issue
* Add some new CSS utilities (`.min-vh-*` and `.opacity-*`)
* Change some rows to have a minimum height so they don't render oddly without data
* Deprecate `.spinner-error` CSS class
* Deprecate accessing the type variable to check user role. Instead you should use `is_admin()`
**Miscellaneous**
* Enable foreign key enforcement for SQLite. Only really matters for the debug server.
* Remove the duplicated `get_config` from `CTFd.models`
* Fix possible email sending issues in Python 3 by using `EmailMessage`
* Dont set User type in the user side session. Instead it should be set in the new user attributes
* Fix flask-profiler and bump dependency to 1.8.1
* Switch to using the `Faker` library for `populate.py` instead of hardcoded data
* Add a `yarn lint` command to run eslint on JS files
* Always insert the current CTFd version at the end of the import process
* Fix issue where files could not be downloaded on Windows
* IP Tracking cache returns the IPs used by the user in the last hour. This way we can track the "Last Seen" value better for GET requests.
* Moves IP addresses in the Admin Panel for Users and Teams into a modal
* Closes#1146
