2.0.17

New new new!

• Cursor now has withMutations
• We're available on Bower!

Bugs Fixed:

• take and skip now return immutable sequences.
• splice behavior now matches Array.prototype.splice

2.0.16

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.

2.0.15

• Source used by node is now not-minified
• withMutations and all complex mutation methods implemented with it (such as merge), now return this when they result in a no-op.
• Fixed bug where a Map key could be incorrectly dropped.
• Cursors now behave as Sequences and share more of the Map API
• Clarify API of update and updateIn

2.0.12

• Fix warnings with node v0.10
• Fix issue with case-sensitive file systems
• Significant performance improvements to Map
• Bug fixes:
  • Deleting key from map can result in incorrect result
  • Deleting key from map can result in thrown error
  • Map iteration was returning incorrect value
  • Map key comparison was incorrect for complex keys (e.g. NaN)

2.0.11

• Bugs:
  • TypeScript resolution was occasionally incorrect
  • pop() of 33-element Vector returned incorrect result.
• Additions:
  • Cursor API expanded
  • Map() constructor now mirrors ES6 spec.
  • Vector's Iterator now adheres to ES6 spec.

2.0.10

• Cursors - Alpha support. Please provide feedback!
• rest and butLast methods.
• Jasmine-check tests - Yay robust!
• API Changes:
  • updateIn now creates empty Maps for missing keys, previously it simply performed no update.
• Fixed bugs:
  • Map inserts with colliding hashes was causing a stack overflow.
  • Unshift >32 elements caused structural failure.
  • Slicing a Range could result in incorrect return value.
  • updateIn and getIn with empty array would throw, now it correctly applys the change to the root element.
