KDE Frameworks 5.91 is here with lots of interesting and exciting changes, starting with a major new feature for the Dolphin file manager and other KDE apps that use the KIO library. This is PolKit support in KIO, which finally enables root file operations in Dolphin.
In addition, the KIO library was improved in this release to correctly handle non-file-based URLs registered to apps, such as tg:// for Telegram links or mailto:// for email addresses, when the apps advertise that they accept URLs. Also, Dolphin now launches faster when there are multiple ISO images mounted or Snap apps installed.
