I am finding there is more to this update than meets the eye in the release notes, I reckon there have been some stealth fixes :
There were some legacy multi-tool weapon upgrade / icon mismatches before which have now been fixed.
Also discovered a long time missing upgrade for the Pulse drive, "Photonix Core" for those of us who pre-ordered the game, this was a nice little extra. It has been absent from the game for a few years. There was also a Multitool Boltcaster upgrade which was part of the Pre-order DLC which went missing at the same time, unfortunately I cant find any evidence of that being back in the game yet.
Screenshot - Before this update the place in the catalogue for the Photonix Core was just a blank space for those of us with the DLC installed -

Anyway, stealthy or otherwise its nice to see some very old issues solved. Wonder how many more things they have done.
It also seems to perform a little better on my system, along with the latest NVidia Drivers .. Probably subjective, and it's hard to tell now I have a decent enough laptop for this game.
