Today we are announcing the latest version of our jQuery SDK - version 2.4.0!

This release contains two important fixes and we encourage everyone to upgrade:

  • This version fixes crashes that can occur on iOS when uploading big videos.
  • This version prevents files from being sent to the final form submit destination in the latest Firefox version causing 413 status headers in some Nginx configurations.

If you are using // or // you will be automatically upgraded.

There also is a change in behavior that you should be aware of:

  • The check if the chosen file's extension matches the values in the file input's accept attribute has been removed. Comparing mime types to file extensions was a bad idea.

This means that you can no longer rely on the accept attribute to prevent users from uploading certain types of files. If this is problematic for you please use the previous version which is available at // Our robots will already ignore file types they don't understand, but if you want to be sure to reject particular files we recommend using our /file/filter bot.

A big thanks goes to Christian Pekeler from DailyChildcareReport who helped us analyze these problems!
