it didn't change much from the h1 goal ✨ notable changes:
We've fixed all the compilation errors in our benchmarks (at least when using in-progress changes) and are now testing some of our benchmarks with the new solver by default. We have already made significant progress on fixing performance regressions, we're still slower than the old solver in the relevant benchmarks
We've done a full crater run and fixed most issues found on crater. Given our in-progress changes there is no unintended major breakage and all intended breakage in widely used crates has been fixed.
