Version 4.2 of the Jottacloud app for Android now uses OpenID Connect authentication. 

You can read more about our transition to OpenID Connect on our blog.

In this release we have also added a PDF viewer to display PDF documents in the app.

In addition to the PDF viewer we've also made many under-the-hood updates that drastically improve the performance of the app, along with some fixes to the background sync service which will ensure that your photo and video backups are taken more frequently.

In this version we have also bumped the minimum required Android version to 5.0 (Lollipop). Read more about this here
