The minor update fixes a "file not found" error some users were experiencing by "revamp[ing] the file-loading system".
The update also adds support for some new 3D printers: the Elegoo Saturn 4 Ultra, Nova 3D Whale 4 Ultra 16K, and – in the filament department – the FLsun S1 Pro.
There are a few more tweaks in there from the 7.2.1 beta, too. Restored TMSC values with a toggle for tilt mechanisms, new display scaling, and improvements to the Lychee Library UI.
