I've done a search of the forum and haven't found any clear answer to this question yet: How does one go about upgrading from 5.0 to 5.1? Do we need to change our /etc/entropy/repositories.conf file to reflect new repositories? I'm asking this because my 5.0 system is "fully up to date" according to Magneto, however, a quick comparison of the changelog for 5.1 vs. 5.0 reveals that I don't have the latest nvidia-drivers or xorg 7.5 as well as other packages new to 5.1; these don't appear to be available or upgradable in Sulfur. If I want a fully up-to-date 5.1 system, how do I achieve this via the package manager and not by using a fresh install? Thanks!

*** EDIT ***
I found the answer and am now updating...
With the 5.0 release, you should be able to roll along and stay current. Anything prior to 5 is in a different branch, hence the equo hop 5 needed to continue updates. At this point and time, I would not recommend doing it, but you are free to try it. Just make sure you have the latest entropy all the time.
As usual, Wolfden's words of wisdom:
equo update
equo install entropy equo
equo world
equo conf update
Only systems <5 need a branch hop!
*** EDIT #2 -still not fully up-to-date ***

Any ideas on how to get fully updated to 5.1? Thanks!
