 This project follows [Semantic Versioning](http://semver.org) guidelines.
 
+## v1.4.2
+### Fixed
+* Fixes logic to disallow creating a backup schedule if the server's backup limit is set to 0.
+* Fixes bug preventing a database host from being updated if the linked node is set to "none".
+* Fixes files and menus under the "Mass Actions Bar" being unclickable when it is visible.
+* Fixes issues with the Teamspeak and Mumble eggs causing installs to fail.
+* Fixes automated query to avoid pruning backups that are still running unintentionally.
+* Fixes "Delete Server" confirmation modal on the admin screen to actually show up when deleting rather than immediately deleting the server.
+
+### Added
+* Adds support for locking individual server backups to prevent deletion by users or automated backup processes.
+* List of files to be deleted is now shown on the delete file confirmation modal.
+* Adds support for using `IF` statements in database queries when a database user is created through the Panel.
+* Adds support for using a custom mailgun API endpoint rather than only the US based endpoint.
+* Adds CPU limit display next to the current CPU usage to match disk and memory usage reporting.
+* Adds a "Scroll to Bottom" helper element to the server console when not scrolled to the bottom currently.
+* Adds support for querying the API for servers by using the `uuidShort` field rather than only the `uuid` field.
+
+### Changed
+* Updates codebase to use TypeScript 4.
+* **[security]**: removes the external dependency for loading QRCode images. They're now generated directly on the frontend using JavaScript.
+
 ## v1.4.1
 ### Added
 * Adds support for only running a schedule if the server is currently in an online state.
