### Security Updates

As a result of security testing and hacking that we did on CKFinder 3 we discovered some potential security concerns in the server-side part of the application. These issues affected actions that only authenticated users could perform solely in locations specified in your CKFinder backends configuration, but since in some cases it was possible to skip ACL checks or file extension checks, an upgrade is highly recommended.

- Reworked the Choose Scaled dialog window.
- Edit Image feature now warns against closing without saving changes.
- Added the `folder:getIcon` request.
- Removed Maximize/Minimize buttons in popup mode as the browser provides native controls for it.
- Improved performance by caching file previews.
- Added the `cache` option that configures cache lifetime for various CKFinder components.
- Added the `tempDirectory` option that configures the path to the temporary files folder used by CKFinder.
- Added the `sessionWriteClose` option that configures whether the connector should close write access to the session to avoid performance issues.
- Added the `Operation` command that tracks the progress of operation in time-consuming connector commands.

### Backward Incompatible Changes
