* Remove Python 2 specific code
* Require imports to have a proper isort-supported order
* Only test/lint on Python 3
* Bump most dependencies to latest supported version
* Add `view=admin` GET param to `/api/v1/users`, `/api/v1/teams`, and `/api/v1/challenges` to bypass filtering for admins
* Closes#1423#1445
* Related to #1165
* Starts work on #929
* Adds Enum classes that can be accessed from JS, Jinja, and Python code. This allows for the sharing of constant values between the three major codebases in CTFd.
* Fix a potential issue where config.py SMTP settings might not have been overrideable from the Admin Panel
* Closes#1306 by using `email.message.EmailMessage` in Python 3. Python 2 will use the old `sendmail` behavior.
* Deprecates storing session["type"] as a means of referring to the user's current level. Instead you should refer to the database.
* Adds `CTFd.utils.user.get_current_user_type()` to get the current user's type or return None if the user is unauthed.
* Closes#1279
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
* Usernames are now properly stripped before being used in registration checks
* Reset password function now uses email addresses instead of user names for tokens
* Prevent MLC users from resetting their password
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)
* Alert
* Background
* Sound On / Sound Off
* There is now a notification counter showing how many unread notifications were received
* Setup has been redesigned to have multiple steps
* Added Description
* Added Start time and End time,
* Added MajorLeagueCyber integration
* Added Theme and color selection
* Fixes issue where updating dynamic challenges could change the value to an incorrect value
* Properly use a less restrictive regex to validate email addresses
* Bump Python dependencies to latest working versions
* Admins can now give awards to team members from the team's admin panel page
**API**
* Team member removals (`DELETE /api/v1/teams/[team_id]/members`) from the admin panel will now delete the removed members's Submissions, Awards, Unlocks
**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/)
* The user-facing navbar now features icons
* Awards shown on a user's profile can now have award icons
* The default MarkdownIt render created by CTFd will now open links in new tabs
* Country flags can now be shown on the user pages
**Deployment**
* Switch `Dockerfile` from `python:2.7-alpine` to `python:3.7-alpine`
* Add `SERVER_SENT_EVENTS` config value to control whether Notifications are enabled
* Challenge ID is now recorded in the submission log
**Plugins**
* Add an endpoint parameter to `register_plugin_assets_directory()` and `register_plugin_asset()` to control what endpoint Flask uses for the added route
**Miscellaneous**
* `CTFd.utils.email.sendmail()` now allows the caller to specify subject as an argument
* The subject allows for injecting custom variable via the new `CTFd.utils.formatters.safe_format()` function
* Admin user information is now error checked during setup
* Added yarn to the toolchain and the yarn dev, yarn build, yarn verify, and yarn clean scripts
* Prevent old CTFd imports from being imported
* The place indicator in Team Mode on the team pages and user pages now excludes counting hidden teams.
* Updated `flask-marshmallow` to 0.10.1, `marshmallow-sqlalchemy` to 0.17.0
* Pinned `marshmallow` to 2.20.2
* Closes#1093
* Closes#1088
* 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.
* Cache the `/scoreboard` page to avoid having to rebuild the response so often
* Update `tests.api.v1.test_scoreboard:test_scoreboard_is_cached` to also test if `/scoreboard` is cached
* Cache get place code for users and teams.
* Fix score changing test helpers to clear standings cache when generating a score changing row
* `utils._get_config` will now return `KeyError` instead of None.
* Separate `/api/v1/[users,teams]/[me,id]/[solves,fails,awards]` into seperate API endpoints
* Install `Flask-DebugToolbar` in development
Main goals covered in #1012
* Change `/api/v1/teams/[team_id]/members` from taking `id` to `user_id`.
* Not even the admin panel was using this endpoint so doesn't seem that drastic of a change
* Add UI to handle team member removal
* Fixes bug where pages marked as `hidden` weren't loading
* It's possible that some users used this behavior however this fix implements the correct behavior. The `draft` setting can be used to completely hide pages.
