Good catch. I'd say you should do all 4 steps for upgrades regardless of what version you're upgrading from, as a precaution - it doesn't hurt either way. Should update the wiki 
I got performance degradation after upgrading to 0.4.1.
It has become terribly slow.
@g6123 I believe we've fixed this, and re-published v0.4.1. Please do a git pull to retrieve the fixes. Sorry about that!
Noticed on this site when I click the Unread button the mark all read icon is black with a Mark_All_Read text that does nothing, if you then F5 the page it loads normally.
There's a magic solution to that: Clear your browser's cache. In the latest code, clicking on it should give you a dropdown menu.
remember that we couldn't ask anyone to clear browser cache after any upgrade
@manuel Actually, I thought we were done with having people clear their caches -- not quite sure why it persisted this time.
@julian i have some issues too after upgrade. some users are getting error 403 when going to notifications page, i asked them to clear browser cache, tomorrow i'll know if it worked
i also noticed that when i open a user profile the first time i don't see the "edit" button, if i refresh it appears
@julian Oh, thanks.. Even though I had upgraded to 0.4.1, the problem remained, but when I completely removed all the files (not mongoDB) and reinstalled it, it has been fixed!
Now its working on my company proxy
