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.

* 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**
* Fix issue with downloading files after CTF end when `view_after_ctf` is enabled

* Redirect to `/team` instead of `/challenges` after a user registers in team mode
* Fixes bug where pages marked as `hidden` weren't loading
* 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.

* 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()`

**Tests**
* Fix score changing test helpers to clear standings cache when generating a score changing row
* Fixes account links on the scoreboard page created by `update()`. They now correctly point to the user instead of undefined when in user mode.
* Add `account_type` and `account_url` field in `/api/v1/scoreboard`
* Temporarily disable foreign keys in MySQL, MariaDB, and Postgres during `import_ctf()`
* Likely also disables SQLite but SQLite is permissive about foreign keys to begin with so irrelevant.
