Hmm.. for me screen tearing not fixable for optimus laptops (intel+ nvidia)
Especially for nvidia
options nvidia-drm modeset=1
in /etc/modprobe.d/nvidia-drm-nomodeset.conf doesn't fix screen tearing.
Thank you! None of the update instructions worked for me either, but -cd did the trick!
Thank you for the shiny new version.
Upgrade was flawless.
Everything is green. (One way and other 
)

Neat! Can't wait to try it.
Sorry dear friend , never , never I install ubuntu-mate... For to be
honest , many changing by the or they kids ? too much no recognize for

As things stand right now - I'm extremely happy with 20.04. Definitely will be leaving this on my main box for a while (although, I'll be honest and probably upgrade to 20.10 in November!)
Big Thumbs up 
to everyone involved with Ubuntu-Mate for a great edition!

Just read the release notes, excited to upgrade in the next few days!
You might want to follow this: Ubuntu Mate LTS with 5 year support?
It looks like a 5-year support is not tenable, in current circumstances (that is, for free). But my suggestion is to have that possibility against a fee, as it is for classical Ubuntu beyond 5 years.
To those who will download Mate 20.04, I suggest to make a donation when offered to do so (https://ubuntu-mate.org/download/amd64/focal/thanks/). Think of what you would pay for an iOS or Windows installation !!
Sorry, but so far this is my worst Linux experience to date 
Had issues installing where "Try without installing" locked up. Finally got it installed by booting directly into the "Install with safe graphics"
Seemed to work fine had my 4K monitor working, got some stuff installed with software boutique, did a bit of surfing with Chrome and Firefox and it looked like I was on my way. Turned off the monitor and went to bed.
Turned the monitor back on this morning and the display was all screwed up -- some how it decided it as 50 dpi. Put it back to my preferred 112 dpi for this 43" display, I could now read it but things just didn't look right, some windows I couldn't scroll to the bottom (control center). Saw some updates were available, installed them and now right after it boots the mouse quits working a few seconds later and the system is dead screen frozen. Total disaster.
This system has been running Mate 16.04 for over a year with only one very annoying minor issue -- it won't shut down unless the laptop lid is open! Good thing I used a fresh SSH instead of wiping my old drive, at least I can go back to 16.04 on the old drive.
Nice job Ubuntu MATE Team. Thanks for hearing the community as usual and for smashing some bugs thanks to the awesome QAs on the team. #FlawlessVictory

I had that problem.
However, you can get round that.
Open a terminal (CTRL + ALT + T) and type
sudo do-release-upgrade -c -d
When terminal confirms the new upgrade available type
sudo do-release-upgrade -d
It will upgrade then for you.
Remember to back up all your files first. It shouldn't lose any files but better safe than sorry.

I did a clean install and it's running smoothly. It feels faster than 18.04. Great job guys!

I always do clean installs after the first point release. I use the meantime to backup my files, bookmarks and make lists of my ppa's and installed programs. I appreciate those that install the first release, but I prefer to avoid the problems they find.

Hi. I had an issue with refresh rate. I solved it in 14.04, 18.04 and 20.04 like this. Maybe it helps.
Bionic Beaver is my favorite name of all the releases.

same lol P.S i did upgrade to 20.04
One weird issue I came across in the new release is that VirtualBox VM windows (unlike the main window) cannot be moved or resized properly with the mouse, which to me looks like a problem with Marco, as Xfce does this just fine in 20.04: https://bugs.launchpad.net/ubuntu-mate/+bug/1876481
