This patch was made available on 15th May 2020. It only adds one change to the 290 patch, the fix list for that is HERE.
The 297 version has only one change – to the display. Some people were not able to install 290 and ending up with a dead install. This was apparently due to the use of Dual Monitors.
So, if you only have one monitor and have no intention of adding another, you can stick with 290.
You should be offered an update to 184.108.40.2067 IF you are running 23.1.242 (or an earlier version). If you reinstall Studio as a new full veersion for the Download link you will get a full version of 297. If you have sucesfully installed 220.127.116.110 already you will not be offered a new patch.
