-
-## [4.1.16] - 2024-02-23
-
-### Added
-
- Add hourly task to automatically require approval for new registrations in the absence of moderators ([ClearlyClaire](https://github.com/mastodon/mastodon/pull/29318), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/29355))
-  In order to prevent future abandoned Mastodon servers from being used for spam, harassment and other malicious activity, Mastodon will now automatically switch new user registrations to require moderator approval whenever they are left open and no activity (including non-moderation actions from apps) from any logged-in user with permission to access moderation reports has been detected in a full week.
-  When this happens, users with the permission to change server settings will receive an email notification.
-  This feature is disabled when `EMAIL_DOMAIN_ALLOWLIST` is used, and can also be disabled with `DISABLE_AUTOMATIC_SWITCHING_TO_APPROVED_REGISTRATIONS=true`.
-
-### Changed
-
- Change registrations to be closed by default on new installations ([ClearlyClaire](https://github.com/mastodon/mastodon/pull/29280))
-  If you are running a server and never changed your registrations mode from the default, updating will automatically close your registrations.
-  Simply re-enable them through the administration interface or using `tootctl settings registrations open` if you want to enable them again.
-
-### Fixed
-
- Fix processing of remote ActivityPub actors making use of `Link` objects as `Image` `url` ([ClearlyClaire](https://github.com/mastodon/mastodon/pull/29335))
- Fix link verifications when page size exceeds 1MB ([ClearlyClaire](https://github.com/mastodon/mastodon/pull/29358))
-
-## [4.1.15] - 2024-02-16
-
-### Fixed
-
- Fix OmniAuth tests and edge cases in error handling ([ClearlyClaire](https://github.com/mastodon/mastodon/pull/29201), [ClearlyClaire](https://github.com/mastodon/mastodon/pull/29207))
-
-### Security
-
- Fix insufficient checking of remote posts ([GHSA-jhrq-qvrm-qr36](https://github.com/mastodon/mastodon/security/advisories/GHSA-jhrq-qvrm-qr36))
-
-## [4.1.14] - 2024-02-14
-
-### Security
-
- Update the `sidekiq-unique-jobs` dependency (see [GHSA-cmh9-rx85-xj38](https://github.com/mhenrixon/sidekiq-unique-jobs/security/advisories/GHSA-cmh9-rx85-xj38))
-  In addition, we have disabled the web interface for `sidekiq-unique-jobs` out of caution.
-  If you need it, you can re-enable it by setting `ENABLE_SIDEKIQ_UNIQUE_JOBS_UI=true`.
-  If you only need to clear all locks, you can now use `bundle exec rake sidekiq_unique_jobs:delete_all_locks`.
- Update the `nokogiri` dependency (see [GHSA-xc9x-jj77-9p9j](https://github.com/sparklemotion/nokogiri/security/advisories/GHSA-xc9x-jj77-9p9j))
- Disable administrative Doorkeeper routes ([ThisIsMissEm](https://github.com/mastodon/mastodon/pull/29187))
- Fix ongoing streaming sessions not being invalidated when applications get deleted in some cases ([GHSA-7w3c-p9j8-mq3x](https://github.com/mastodon/mastodon/security/advisories/GHSA-7w3c-p9j8-mq3x))
-  In some rare cases, the streaming server was not notified of access tokens revocation on application deletion.
- Change external authentication behavior to never reattach a new identity to an existing user by default ([GHSA-vm39-j3vx-pch3](https://github.com/mastodon/mastodon/security/advisories/GHSA-vm39-j3vx-pch3))
-  Up until now, Mastodon has allowed new identities from external authentication providers to attach to an existing local user based on their verified e-mail address.
-  This allowed upgrading users from a database-stored password to an external authentication provider, or move from one authentication provider to another.
-  However, this behavior may be unexpected, and means that when multiple authentication providers are configured, the overall security would be that of the least secure authentication provider.
-  For these reasons, this behavior is now locked under the `ALLOW_UNSAFE_AUTH_PROVIDER_REATTACH` environment variable.
-  In addition, regardless of this environment variable, Mastodon will refuse to attach two identities from the same authentication provider to the same account.
-

-
-### Security
-
- Fix insufficient origin validation (CVE-2024-23832, [GHSA-3fjr-858r-92rw](https://github.com/mastodon/mastodon/security/advisories/GHSA-3fjr-858r-92rw))
