- 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

Add cache_timeout parameter to send_fileresponse 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

Fixes populate.py to assign captains to teams.

Models

Added Challenges.flags relationship and moved the Flags.challenge relationship to a backref on Challenges

- 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

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

2.1.0 / 2019-04-24

General

Remove Flask-SocketIO in favor of custom Server Side Events code
- Removed the Flask-SocketIO dependency and removed all related code. See Deployment section.
- Added EventSource polyfill from Yaffle/EventSource
- Events are now rate-limited and only availble to authenticated users
  - This means real time notifications will only appear to authenticated users

- To file uploads on the page editor page
- To the import CTF functionality
Challenge file downloads now require a token to download
- /files/<path> now accepts a ?token= parameter which is a serialized version of {user_id: <>, team_id: <>, file_id: <>}
- If any of these sections are invalid or the user/team is banned the download is blocked
- This allows files to be downloaded via curl or wget (i.e. without cookie authentication)
Added a team captain concept. Team captains can edit team information such as name, team password, website, etc.
- Only captains can change their team's captain
- Captains are the first to join the team. But they can be transferred to the true captain later on
Cache /api/v1/scoreboard and /api/v1/scoreboard/top/[count]

- team.html -> teams/public.html and teams/private.html
Separate admin/templates/modals/users/create.html into admin/templates/modals/users/edit.html

Exports

Exports will now properly export JSON for all JSON columns
- In some configurations the column would be exported as a string.
- Legacy string columns will still be imported properly.
Exports from old 2.x CTFd versions should upgrade and be installed properly
- Any failure to do so should be considered a bug

Deployment

Default worker changed back to gevent
Removed Flask-SocketIO dependency
- Removed the SOCKETIO_ASYNC_MODE config
gevent is now required to allow the Server Sent Events client polling code to work

Install gevent-websocket and use it by default until we have a better solution
NOTE: In future releases, websockets functionality will likely be removed. (#852)

2.0.3 / 2019-01-12

Security Release

This release resolves a security issue that allowed malicious users to hijack admin browser sessions in certain browsers under certain configurations.

The implemented fix is to require the new CSRF-Token header on state-changing requests with a Content-Type of application/json. The same nonce used for standard POST requests is re-used for the CSRF-Token header.

Because of the necessary changes to the API, the previously used call to fetch() in themes should now be replaced with CTFd.fetch().

Security

Require CSRF-Token header on all API requests.
Require CSRF protection on all HTTP methods except GET, HEAD, OPTIONS, and TRACE.
Default session cookie to SameSite=Lax
Send initial user information request to MajorLeagueCyber over HTTPS

General

Fix update_check() logic so that we don't accidentally remove the update notification.

Themes

Remove explicit usage of script_root in public JS.
- In custom themes, use the CTFd.fetch() function (defined in CTFd.js) and properly register the url root and CSRF nonce in base.html as shown below:
```
var script_root = "{{ request.script_root }}";
var csrf_nonce = "{{ nonce }}";
CTFd.options.urlRoot = script_root;
CTFd.options.csrfNonce = csrf_nonce;
```
Reduce required amount of parameters required for static theme files.
- i.e. url_for('views.themes') no longer requires the themes parameter. It now defaults to the currently in-use theme.

2.0.2 / 2019-01-03

General

Fix regression where public challenges could not be attempted by unauthed users.
Admin Config Panel UI no longer allows changing of user mode.
Show notification titles and allow for deleting notifications
- Update notification UI in admin panel to be similar to the public-facing UI
Fix subdirectory deployments in a generic manner by modifying request.path to combine both request.script_root and request.path.
- Also create a request preprocessor to redirect users into the true CTFd app when deploying on a subdirectory.
- Redirect to request.full_path instead of just request.path.
Fix TestingConfig.SAFE_MODE not being reset between tests.
Disable value input in dynamic challenge update field since we calculate it on the user's behalf.
Fix displaying incorrect account link in the solves tab of a challenge modal.
Pin normality version because of an upstream issue in dataset.
Fix 500's when users submit non-integer values to ?page=1

API

Add /api/v1/notifications/<id> to allow accessing notifactions by ID.
- This is currently public but will become permission based later in the future
Add account_url field to the response of /api/v1/<challenge_id>/solves so the client knows where an account is located.

Plugins

Add new plugin utilities to register javascript and css files for the admin panel.
- Also fixed issue where those scripts and files were shared between generated applications

2.0.1 / 2018-12-09

2.0.1 is a patch release to fix regressions and bugs in 2.0.0.

2.0.0 / 2018-12-02

2.0.0 is a significant, backwards-incompaitble release.

Many unofficial plugins will not be supported in CTFd 2.0.0. If you're having trouble updating your plugins please join the CTFd Slack for help and discussion.

If you are upgrading from a prior version be sure to make backups and have a reversion plan before upgrading.

If upgrading from 1.2.0 please make use of the migrations/1_2_0_upgrade_2_0_0.py script as follows:
1. Make all necessary backups. Backup the database, uploads folder, and source code directory.
2. Upgrade the source code directory (i.e. git pull) but do not run any updated code yet.
3. Set the DATABASE_URL in CTFd/config.py to point to your existing CTFd database.
4. Run the upgrade script from the CTFd root folder i.e. python migrations/1_2_0_upgrade_2_0_0.py.
  - This migration script will attempt to migrate data inside the database to 2.0.0 but it cannot account for every situation.
  - Examples of situations where you may need to manually migrate data:
    - Tables/columns created by plugins
    - Tables/columns created by forks
    - Using databases which are not officially supported (e.g. sqlite, postgres)
5. Setup the rest of CTFd (i.e. config.py), migrate/update any plugins, and run normally.
If upgrading from a version before 1.2.0, please upgrade to 1.2.0 and then continue with the steps above.

- Challenge type plugins also have access to window.challenge.data which allow for the previously mentioned functions to process challenge data and change logic accordingly.
Challenge type plugins now get full control over how a challenge is displayed via the nunjucks files.
