Hello and welcome newbie !!
Glad to see you here !
In answer to your first question , No, You can't (At this point) Upgrade to a new release of Ultimate Edition with "one "click",you must do a fresh install of each new release, which really is not as bad as it sounds ! you simply backup your important documents (Home folder) and install the new release, There are also backup app's to help with the transition, TheeMahn has been working on a "One click" type upgrade for the system,But with "Lucid" coming out some time in April (By reports) and it having an all new start-up interface, This would be possible but not probable;you see each release of Ultimate Edition is a brand new issue not a rehash of the last release, and sometimes things wont hitch up an drive, But I do believe once things are running stable and Canonical stops playing with the interface, TheeMahn will be able to deliver on a "One click" upgrade! may be not for every release but that remains to be seen ! He is cool like that !
AS for your second question, As Canonical starts there development process so do we ! we are right on there heals and sometimes, Ahead and have to wait for them to catch up !
So as soon as TheeMahn knows for sure that there release is stable and on schedule, Ultimate Edition (2.6) will not be far behind !! Thanks again for climbing on board ! It's great to have you here !
This post will more than likely be moved to General discussion or Newbie's corner, FYI.
