2.3.3 / 2020-04-12
==================
**General**
* Re-enable the Jinja LRU Cache for **significant speedups** when returning HTML content
**API**
* `POST /api/v1/unlocks` will no longer allow duplicate unlocks to happen
**Admin Panel**
* Makes `Account Visibility` subtext clearer by explaining the `Private` setting in Config Panel
**Themes**
* Fixes an issue with using a theme with a purely numeric name
* Fixes issue where the scoreboard graph always said Teams regardless of mode
**Miscellaneous**
* Bump max log file size to 10 MB and fix log rotation
* Docker image dependencies (apk & pip) are no longer cached reducing the image size slightly
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**
* Fix behavior for `REVERSE_PROXY` config setting when set to a boolean instead of a string
* Improve `Dockerfile` to run fewer commands and re-use the build cache
* Add `make coverage` to generate an HTML coverage report
* Update `coverage` and `pytest-cov` development dependencies
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
2.2.3 / 2020-01-21
==================

* 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.

**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
* Create an `ezToast()` function to use [Bootstrap's toasts](https://getbootstrap.com/docs/4.3/components/toasts/)

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

* 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

* 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

* 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.
