15.1.0

Added

• HashSet now implements From<Vector<A>> and From<&Vector<A>> where A: Clone.

• Fixed

• Fixed a long standing crash bug in OrdMap/OrdSet. (#154, #143, #152, #124)

• The union method on maps/sets will now prefer to mutate the larger set (which leads to less work) rather than the first set. (#163)

• Ensure TreeFocus only implements Send/Sync when the underlying type does. (#157, #158)

• There was an issue where nodes in very large OrdMaps could overflow when removing an element and cause a panic, which has now been fixed. (#141)

• Assorted doc cleanup. (#150, #173, #186, #194)
