Tank v2.1

What’s the deal with the new v2.1 tank? Is it more durable then v2 (cause 2months life really sucks if you want to use diverse materials) or is it just for new wax resin with no other benefits?
Need to buy few tanks and considering whether should I wait for 3 weeks to buy v2.1 or just take v2 now.

The release notes say the change is only for compatibility with the new castable wax resin.

That said, Formlabs release notes tend to be pretty cryptic and often do not mention other changes. Perhaps we won’t know until people start trying out the new trays.

I know it doesn’t state it now, but I could swear when the v2.1 tray came out there was a 2nd resin that also required the tray. Was I just imagining it or can anyone remember what it was?

Here’s the grid of which tanks support which resins:

Not sure about any others beyond Castable Wax which were announced to need v2.1.

Yes, as I say, I know v2.1 is NOT required for Tough 2000 now, but I swear I was reading it on the formlabs site about a month ago that it was now required for more than just one resin
