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.

* 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

All CTFd administrators are recommended to take the following steps:
1. Upgrade their installations to the latest version
2. Rotate the `SECRET_KEY` value
3. Reset the passwords for all administrator users
**Security**
* This release includes a fix for a vulnerability allowing an arbitrary user to take over other accounts given their username and a CTFd instance with emails enabled
**General**

* Fixed an error when users provided incorrect team join information
2.2.2 / 2020-01-09
==================
**General**

* Fix issue with timezone loading in config page which was preventing display of CTF times
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.
**General**
* Team size limits can now be enforced from the configuration panel
* Access tokens functionality for API usage
* Admins can now choose how to deliver their notifications
* Toast (new default)

**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)
* Static theme assets are also given a `d` GET parameter that changes per server start. Used to bust browser caches.
* 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

2.1.4 / 2019-08-30
==================
**General**
* Make user pages show the team's score and place information instead of the user's information if in team mode
* Allow admins to search users by IP address
* Require password for email address changes in the user profile
* The place indicator in `Teams Mode` on the team pages and user pages now correctly excludes hidden teams

* Show affiliation in user and team pages in the admin panel and public and private user and team pages
**Themes**
* Remove invalid `id='submit'` on submit buttons in various theme files
* Set `tabindex` to 0 since we don't really care for forcing tab order
* Rename `statistics.js` to `graphs.js` in the Admin Panel as it was identified that adblockers can sometimes block the file
**API**
* The team profile endpoint (`/api/v1/teams/me`) will now return 403 instead of 400 if the requesting user is not the captain
* The Challenge API will now properly freeze the solve count to freeze time
2.1.3 / 2019-06-22
==================
**General**

* Remove `data-href` from `pages.html` in the Admin Panel to fix the delete button
* Add UI to handle team member removal in Admin Panel
* Fixes account links on the scoreboard page created by `update()`. They now correctly point to the user instead of undefined when in user mode.
* `utils._get_config` will now return `KeyError` instead of `None` to avoid cache misses
**Deployment**
* Use `/dev/shm` for `--worker-tmp-dir` in gunicorn in Docker
* Cache `get_place` code for users and teams.
* Install `Flask-DebugToolbar` in development
* Cache the `/scoreboard` page to avoid having to rebuild the response so often
* Make unprivileged `ctfd` user usable for mysql connection in docker-compose by having the db image create the database instead of CTFd
* Fix bug causing apache2 + mod_wsgi deployments to break
**API**
* Change `/api/v1/teams/[team_id]/members` from taking `id` to `user_id`.
* Endpoint was unused so the API change is considered non-breaking.
* Add `account_type` and `account_url` field in `/api/v1/scoreboard`
* Separate `/api/v1/[users,teams]/[me,id]/[solves,fails,awards]` into seperate API endpoints
* Clear standings cache after award creation/deletion
**Exports**
* Temporarily disable foreign keys in MySQL, MariaDB, and Postgres during `import_ctf()`
* Add `cache_timeout` parameter to `send_file`response in `/admin/export` to prevent the browser from caching the export
**Tests**
* Fix score changing test helpers to clear standings cache when generating a score changing row
2.1.2 / 2019-05-13
==================
**General**
* Fix freeze time regressions in 2.x
* Make `/api/v1/[users,teams]/[me]/[solves,fails,awards]` endpoints load as admin so users can see their solves after freeze
* Make `/api/v1/challenges/[id]/solves` only show solves before freeze time
* Add the `?preview=true` GET parameter for admins to preview challenges solves as a user
* Team join attempts are now ratelimited
**Tests**
* More linting and autoformatting rules
* Format Javascript and CSS files with `prettier`: `prettier --write 'CTFd/themes/**/*'`
* Format Python with `black`: `black CTFd` and `black tests`
* `make lint` and thus Travis now include the above commands as lint checks
* Travis now uses xenial instead of trusty.
2.1.1 / 2019-05-04
==================
**General**
* Allow admins to hit `/api/v1/challenges` and `/api/v1/challenges/[id]` without having a team to fix challenge previews
* Fix rate-limiting of flag submission when using team mode
* Fixes some modal close buttons not working in the admin panel
* Fixes `populate.py` to assign captains to teams.
**Models**
* Added `Challenges.flags` relationship and moved the `Flags.challenge` relationship to a backref on Challenges
* Added `ondelete='CASCADE'` to most ForeignKeys in models allowing for deletions to remove associated data
* `Hints` should be deleted when their Challenge is deleted
* `Tags` should be deleted when their Challenge is deleted
* `Flags` should be deleted when their Challenge is deleted
* `ChallengeFiles` should be deleted when their Challenge is deleted
* Deletion of the file itself is not handled by the model/database
* `Awards` should be deleted when their user or team is deleted
* `Unlocks` should be deleted when their user or team is deleted
* `Tracking` should be deleted when their user or team is deleted
* `Teams.captain_id` should be set to NULL when the captain user is deleted
**Exports**
* Force `db.create_all()` to happen for imports on `sqlite` or on failure to create missing tables
* Force `ctf_theme` to be set to `core` in imports in case a theme is missing from the import or the instance
* Fix imports/exports to emit and accept JSON properly under MariaDB
* MariaDB does not properly understand JSON so it must accept strings instead of dicts
* MariaDB outputs strings instead of JSON for its JSON type so the export serializer will attempt to cast output JSON strings to JSON objects
**Deployment**
* Run as root when using docker-compose
* This is necessary to be able to write to the volumes mounted from the host
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.
