the only known issue among the dozens of f10 installs of amahi to date is that the first user created (not root) is not created with amahi's UI, so there is no way to use shares with this user, because a samba user does not exist for that user.
the work-around is to delete that user (not root!) and create one via the setup pages in amahi.
we're going to cope with this soon by putting a little warning icon next to the user and hopefully that may work.
then, resetting the password for that user should be enough.
for f11, as we usually do with any new release, we wait a few weeks until the reports on stability and usual zero-day updates and fixes come in.
also, it depends on how many people we have helping developing/testing amahi on the new release.
does that help answer your question(s)?
