3.7.4

Fixes:

• isSuperset can be called with an array of values.

New:

• contrib/Cursor has proper support for Record
• tsc will pick up type definitions from node modules

3.7.3

Fixes:

• Improvements to documentation around equality, hasIn and withMutations
• Iterating over empty slice no longer throws.
• Merge deep methods no longer throw if deep position is not mergeable.

3.7.2

• Updated PATENTS to v2.
• Minor improvements to docs and Readme

3.7.1

New:

• contains() is now called includes() to match the ES6 specification. contains() still exists as an alias.

3.7.0

New:

• merge() family of functions now get the currently merging key as a 3rd argument, in case merge strategy should alter based on key.
• IndexedCursor now has push(), pop(), unshift() and shift() to more closely mirror List.
• Records initialize lazily. Creating a new Record type with Record({foo:"bar"}) involves a small bit of work. For applications with a large amount of Records, lazy initialization should help startup times.
• Maps can now be constructed by a List of Lists instead of only a List of Arrays.
• toString() prints Map string keys in quotes.

Fixes:

• is() allows usage of valueOf to return primitives without recursing or encountering a reference error.
• merge()/union() work inside withMutations when initial collection is empty. #405
• Producing subcursors using cursor.cursor() now returns a proper typed cursor. #381
• When a Record is passed to the same Record creation function, it's now returned directly.
• Ensure Records toString() correctly. #383
• Iterating over a sliced Seq can no longer cause an infinite recursion. #394
• Ensure we don't throw when hashing non-extensible object in a modern environment.
• Fix issue where non-existent function could be called if a collection doesn't have a size.

3.6.4

Fixes:

• 3.6.3 was a broken npm release.

3.6.3

Fixes:

• Improve test coverage of Stack, fixing #332 and #353
• Numerous typo fixings. Me spel gud.
• Fix collection toString() when an ES6 Symbol is a value in the collection.
• Consider a prototype-free object a "plain object". Fixes #302
• No long enumerates extra key in canDefineProperty in rare cases in some versions of Chrome

3.6.2

Fixes:

• Improves performance of creating Cursors.

3.6.1

Fixes:

• Iterating over a Cursor to a List could result in an infinite loop.

3.6.0

New:

• findEntry() and findLastEntry() will return [key, value] tuples of the first value to pass a predicate. Related to find() and findLast() which only return value.
• contrib/Cursor now has the wider suite of methods found on List and Map including:
  • updateIn()
  • setIn()
  • deleteIn()
  • merge()
  • mergeWith()
  • mergeIn()
  • mergeDeep()
  • mergeDeepWith()
  • mergeDeepIn()

Fixes:

• UMD module wrapper safer to use with CommonJS -> AMD bundlers.
• Clarified some examples in documentation
