CKFinder 3.4.2 released

We are happy to announce that CKFinder 3.4.2 has been released on June 26, 2017 (PHP) and August 4, 2017 (ASP.NET). This version contains some important updates for remote storages (Amazon S3 and Dropbox) for the PHP connector, minor bug fixes for the ASP.NET connector and two new localizations: Azerbaijani and Uzbek. In addition to that, minimal PHP requirements were bumped, too. Read on for more information!

Amazon S3 backend update for the PHP connector

The AWS SDK used in CKFinder for PHP was updated to version 3. This affects Amazon S3 cloud storage and should bring plenty of improvements, including to performance. More details are available on Amazon Web Services blog!

Dropbox backend update for the PHP connector

Dropbox API was updated to version 2, as Dropbox is turning off the deprecated version 1 that was previously used in CKFinder 3 for PHP. If you wish to continue using your Dropbox storage, you need to upgrade to CKFinder 3.4.2.

PHP system requirements

CKFinder 3.4.2 requires PHP 5.6+ to work correctly. Additionally, Dropbox backend requires PHP 7.0+. The last version to support PHP 5.4 is CKFinder 3.4.1.


CKFinder 3.4.2 includes two new localizations: Azerbaijani and Uzbek (Cyrillic and Latin versions). Vietnamese translation was updated, too. Many thanks to our translators!
