Newly-created accounts are allowed to log in straight away, but they still have the permissions of a guest until they've confirmed their email address. Instead of showing a success message after registration, we reload the page since they're already logged in.
Still todo: show a message explaining that they need to verify their email address to do anything, and allow it to be resent.
- Use Symfony's Session component to work with sessions, instead of a custom database model. Separate the concept of access tokens from sessions once again.
- Extract common session/remember cookie logic into SessionAuthenticator and Rememberer classes.
- Extract AuthenticateUserTrait into a new AuthenticationResponseFactory class.
- Fix forgot password process.
- Use cookies + CSRF token for API authentication in the default client. This mitigates potential XSS attacks by making the token unavailable to JavaScript. The Authorization header is still supported, but not used by default.
- Make sensitive/destructive actions (editing a user, permanently deleting anything, visiting the admin CP) require the user to re-enter their password if they haven't entered it in the last 30 minutes.
- Refactor and clean up the authentication middleware.
- Add an `onhide` hook to the Modal component. (+1 squashed commit)
Specifically, the crash would occur when the first notification had a subject without a discussion relationship (e.g. the Subscriptions extension's newPost notification, where the subject itself was a discussion). Instead of simply eager loading the nested subject.discussion relationship, we load discussions manually instead.
This means that the "Start a Discussion" button will still be enabled if the user is not allowed to start globally, but only in certain tags.
Also add some other stuff to the changelog.
