Hi,
- last dnf update took far too much time
- shutdown process not tolerable, takes too much time.
- usb connection erroneous. i.e. after copying to flash medium or external disk connected by an usb adapter in most trials, when I try to eject the usb connected medium, there - after a copying process is finished a long time ago - comes the message "usb medium in use", this for ever. Also after shutdown of F25 in some cases I had to repair the usb connected medium with a new partition table. Things like that are not nice.

Conclusion: I use F24 and if F26 will be better switch to F26 and omit F25.
Kind regards
