Some of the menus have changed slightly, check the new options and eventually set everything how it was before prior to comparing performances.
For example there is a new entry called Traffic Variety in the traffic section. 

I think also the slight image deformation for screens with different ratio than 16:9 has been fixed 

I'm unable to get the APU turn on on the FBW A320. Anyone else?

FBW A320 mod is broken. It will break with every update that touches the base A320 files.

SDK 0.9.0.0 is available, not sure it is linked to this release or it was already available though

@Server Announcements With the latest sim update released 22nd December, we have identified multiple issues with the A32NX mod resulting in the mod not working as intended. Rest assured the team are working hard to resolve this issue as soon as possible and we shall update you when we have any further news. Before reporting any problems with the A32NX, please ensure you have deleted the mod from your community folder and reinstalled using the installer linked in #a320-releases and restarted the simulator. You should look in #known-issues to check your issue is not already reported before seeking support in #help

everything worked as expected. 

Thanks for the update, great to hear!

I was afraid of buying the Mooney and Seminole yesterday only to have them in the hangar for a month.

Guys, you all need to pay attention.  It's been posted here in this thread a million times already....the FBW is broke.  They are fixing it now.

Also...the grainy clouds fix is only for certain GPUs...this is NOT the main fix. That's coming in a future sim update.

Did a 30 minute flight in the Mooney, with the GNS530 mod. Both working fine so far!

Only 2 Gigs to go. System is flying at 23 Mbits/sec. Ugh.

CJ4 pitch trim is now backwards

Clouds have not changed on HIGH only ULTRA back to original but with performance hit

Sim overall seems smoother

The Missouri River at KOMA has been finally fixed. Terrain spikes just North of the airport are still present from the last update though.

Just tested out the new update. Unfortunately the 2 items I was really hoping would be fixed are not. Mountains and even general small elevations of the mesh are still "morphing" right near the plane. The coastline glitch is still as present as ever. After seeing how beautiful and convincing this sim has been & can be from a visual stand point, I just can't accept the current visual state of it. It's back to DCS for me until the next update. Cheers

I mean honestly, I think you can just assume ALL mods will break when they do these updates
