I have had a few years of trouble free running. Now, since you removed the 'Convert Link' button and made it automatic, (which is good!), there seem to be less-good side effects.
Trying to post a reply on a thread, it does not 'go anywhere' and just sits there. I am wise to this now: so I Ctrl A, put the content in a text document, then find the 'log in' sign, log in for the SECOND time, put the text back into the thread, and post successfully.
Also, I notice threads I have been onto are not turning 'pink' (or whatever the colour is) which they always used to do, to show 'where one had been'. This also, I think, has only happened since the update.
I am using and 'office' style computer, with Linux and Firefox.
Kind regards to you all, and have a good Easter, when it comes.
