Oh Thank goodness, I thought I was the only 1 to have this problem. It has been a massive ball ache since I updated as well. Before I had no problems with PLA. Only had problems with the Formfutura Brass filled one. But now it is with all my filaments.
clean your nozzle and knurled wheel yet?
Not sure if you are asking me, but yes I have.
Why yes, I am!! 
The pic you posted has dramatic underextrusion, can you see light through the nozzle after atomic pulls?
Turns out its your filament diameter, you gotta make sure to update that value in Cura or it will fail this way. it works much better now that I changed it

UltiMaker Cura 5.3 stable released
ArunC posted a topic in Ultimaker Cura,
In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!-

Here it is. The new UltiMaker S7
MariMakes posted a topic in Official news,
The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
So what’s new?
The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
The UltiMaker S7 also includes quality of life improvements:
Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more
Curious to see the S7 in action?
We’re hosting a free tech demo on February 7.
It will be live and you can ask any questions to our CTO, Miguel Calvo.

Cura Alpha With New Tree Support 🎄
MariMakes posted a topic in Ultimaker Cura,
Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.-

Hi and welcome,
That looks like massive underextrusion, are you sure it's related to the slicer? Does an older gcode with your previous version do the same? It might be related to hardware
