The next update will be for the X1/P1 Spares Case, which will get a stronger door (on the version with a compartment in the base instead of the glue holders), an optional 5x full hot end holder, and modular latches. The biggest deal for me are the modular latches, which I hope will resolve a rare (but annoying) problem some users have reported during assembly of the case. They had cracked the base when they tried to latch the case, with latches that were too tight. The problem was resolved by adding longer latch options, but modular latches will hopefully avoid the issue at the source, since the weakest part of the latch can now be printed in an orientation that will give it greater strength.
Update 3/12/2025 - The X1/P1 Spares Case has been update to v3.0. You can find it over on MakerWorld:

And finally, I thought I'd just add a pic of a clog I recently had to clear in the internal AMS hub on my Bambu X1C's AMS unit (pic below). The process is described here, and the only things I'd add are that a toothbrush is great for cleaning the filament dust out, and that I took care not to disturb the orientation of the four small magnets near the pneumatic couplers.
