Thanks for the update!

You had me worried at first - I don't think any of the most active
developers are currently doing anything with subdivision elements,
which is exactly the sort of situation where regressions are a risk.
Good to hear that wasn't the case.

How far in the "stronger linear solver" direction did you have to go?
Stronger tolerance(s); stronger preconditioner; direct instead of
iterative?
