3.3.0

New:

• setIn added to Record
• Added mergeIn and deepMergeIn to Map and List.
• updateIn, and all *In methods accept any Iterable as key path, not just Array.
• Optimization for concat, merge and union. If this is empty, and a single non-empty argument is provided, then attempt to return the argument unmodified.

Fixes:

• Documentation improvements
• Tests to ensure equality symmetry and hash equality
• Performance improvements to collection hashing
