+Fixed: PreconditionChebyshev would previously run one iteration more than
+requested, i.e., perform `degree+1` matrix-vector products rather than
+`degree` which is the convention in literature. This is now fixed. Note that
+the quality of PreconditionChebyshev is obviously slightly reduced by this
+change, and some solvers might need more outer iterations due to a ligher
+Chebyshev iteration.

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
