Breaking Changes:

• Sequence's keys, values, entries and fromEntries renamed to keySeq, valueSeq, entrySeq and fromEntrySeq respectively.

Features Added:

• Sets can now contain Collections and JS Objects
• Maps can now use Collections and JS Objects as keys
• ES6 Iteration methods, keys, values and entries, added to all concrete collections.
• concrete collections can be used directly in ES6 for-of loops
• Vector iterator follows ES6 spec: dense iteration but adds an optional param to get sparse iteration.
• Improved performance of Vector iteration and folding.

Bugs Fixed:

• IE8 no longer complains about "delete" used as a method
• Cursor access and sequence methods now always return Cursors.
