I always check on the latest desktops which includes the latest E release to see how they compare to Moksha periodically. This was the first time I'd used Enlightenment in awhile and it wasn't a dumpsterfire of crashes and lockups so I put the package I built into the repos for folks who want to try it.
I spent half a day on it before I grew tired of not having a working systray and lacking modules I use in Moksha.
Clearing settings and reinstalling Midori isn't going to fix issues. It is a light browser that has a hard time with heavier web pages. If you are doing anything complex (especially involving flash) I would recommend installing Chrome or Firefox.
The actual answer is that unless you need bleeding edge software - there is no rush to upgrade. All Bodhi releases have support for 5 years. I still have Bodhi 3 systems in my house and likely will until they stop running or can't update Chrome any more.
People have this obsession with being on the "latest and greatest" and always insist on "fixing" things that aren't broken.
Cruise the support forums of Ubuntu and other major OSes that do in place operating systems after a major one comes out. Almost every time you will find countless people with things breaking because of it.
We are a small team and I personally don't want to deal with the complexity of the infinitely many configurations people's computers can be in at the time we do an in place system upgrade.
Also - in the future please consider using a more descriptive topic title. I've edited this one so it is clear what you are asking.
Note that this is only tested / supported on 16.04 based installations as we only build on Ubuntu LTS releases. I would also recommend trying the latest 4.2 release though as suggested above as it does have a newer kernel than previous versions. Hit any issues let us know.
