v2.2.1

Improves compatibility with forthcoming SageMath 10.1.

v2.2

Selected speedups, code cleanup (thanks to Frédéric Chapoton), and extended Tangle (thanks to Kyle Miller).

v2.1

Major speedup in Link simplification code for large (100+ crossing) links.

v2.0

• Convention changes: Sign of knot signature (now positive knots have
  negative signatures), choice of braid generators (now positive
  generators give positive crossings).

• Faster "local" algorithm for the Jones polynomial

• Incorporates Zoltán Szabó's program for computing knot Floer homology.

• Link now accepts DT codes.

v1.8.3
