Note for users of v4.0.0-rc.12

There were mostly bugfixes and improvements since RC 12. Upgrading should be painless for most users. However, there is one breaking change: The behavior of merge and mergeDeep has changed. See below for details.

BREAKING

merge()

  • No longer use value-equality within merge() (#1391)

    This rectifies an inconsistent behavior between x.merge(y) and x.mergeDeep(y) where merge would use === on leaf values to determine return-self optimizations, while mergeDeep would use is(). This improves consistency across the library and avoids a possible performance pitfall.

  • No longer deeply coerce argument to merge() (#1339)

    Previously, the argument provided to merge() was deeply converted to Immutable collections via fromJS(). This was the only function in the library which calls fromJS() indirectly, and it was surprising and made it difficult to understand what the result of merge() would be. Now, the value provided to merge() is only shallowly converted to an Immutable collection, similar to related methods in the library. This may change the behavior of your calls to merge().

mergeDeep()

  • Replace incompatible collections when merging nested data (#1840)

    It will no longer merge lists of tuples into maps. For more information see #1840 and the updated mergeDeep() documentation.

  • Concat Lists when merging deeply (#1344)

    Previously, calling map.mergeDeep() with a value containing a List would replace the values in the original List. This has always been confusing, and does not properly treat List as a monoid. Now, List.merge is simply an alias for List.concat, and map.mergeDeep() will concatenate deeply-found lists instead of replacing them.

Seq

  • Remove IteratorSequence. Do not attempt to detect iterators in Seq(). (#1589)

    Iterables can still be provided to Seq(), and most Iterators are also Iterables, so this change should not affect the vast majority of uses. For more information, see PR #1589

  • Remove Seq.of() (#1311, #1310)

    This method has been removed since it cannot be correctly typed. It's recommended to convert Seq.of(1, 2, 3) to Seq([1, 2, 3]).

isImmutable()

  • isImmutable() now returns true for collections currently within a withMutations() call. (#1374)

    Previously, isImmutable() did double-duty of both determining if a value was a Collection or Record from this library as well as if it was outside a withMutations() call. This latter case caused confusion and was rarely used.

toArray()

  • KeyedCollection.toArray() returns array of tuples. (#1340)

    Previously, calling toArray() on a keyed collection (incl Map and OrderedMap) would discard keys and return an Array of values. This has always been confusing, and differs from Array.from(). Now, calling toArray() on a keyed collection will return an Array of [key, value] tuples, matching the behavior of Array.from().

concat()

  • list.concat() now has a slightly more efficient implementation and map.concat() is an alias for map.merge(). (#1373)

    In rare cases, this may affect use of map.concat() which expected slightly different behavior from map.merge().

Collection, formerly Iterable

  • The Iterable class has been renamed to Collection, and isIterable() has been renamed to isCollection(). Aliases with the existing names exist to make transitioning code easier.

Record

  • Record is no longer an Immutable Collection type.
    • Now isCollection(myRecord) returns false instead of true.
    • The sequence API (such as map, filter, forEach) no longer exist on Records.
    • delete() and clear() no longer exist on Records.

Other breaking changes

  • Potentially Breaking: Improve hash speed and avoid collision for common values (#1629)

    Causes some hash values to change, which could impact the order of iteration of values in some Maps (which are already advertised as unordered, but highlighting just to be safe)

  • Node buffers no longer considered value-equal (#1437)

  • Plain Objects and Arrays are no longer considered opaque values (#1369)

    This changes the behavior of a few common methods with respect to plain Objects and Arrays where these were previously considered opaque to merge() and setIn(), they now are treated as collections and can be merged into and updated (persistently). This offers an exciting alternative to small Lists and Records.

  • The "predicate" functions, isCollection, isKeyed, isIndexed, isAssociative have been moved from Iterable. to the top level exports.

  • The toJSON() method performs a shallow conversion (previously it was an alias for toJS(), which remains a deep conversion).

  • Some minor implementation details have changed, which may require updates to libraries which deeply integrate with Immutable.js's private APIs.

  • The Cursor API is officially deprecated. Use immutable-cursor instead.

  • Potentially Breaking: [TypeScript] Remove Iterable<T> as tuple from Map constructor types (#1626)

    Typescript allowed constructing a Map with a list of List instances, assuming each was a key, value pair. While this runtime behavior still works, this type led to more issues than it solved, so it has been removed. (Note, this may break previous v4 rcs, but is not a change against v3)

New

  • Update TypeScript and Flow definitions:
    • The Flowtype and TypeScript type definitions have been completely rewritten with much higher quality and accuracy, taking advantage of the latest features from both tools.
    • Simplified TypeScript definition files to support all UMD use cases (#1854)
    • Support Typescript 3 (#1593)
    • Support Typescript strictNullChecks (#1168)
    • Flow types to be compatible with the latest version 0.160.0
    • Enable flow strict (#1580)

  • Add "sideEffects: false" to package.json (#1661)

  • Use ES standard for iterator method reuse (#1867)

  • Generalize fromJS() and Seq() to support Sets (#1865)

  • Top level predicate functions (#1600)

    New functions are exported from the immutable module: isSeq(), isList(), isMap(), isOrderedMap(), isStack(), isSet(), isOrderedSet(), and isRecord().

  • Improve performance of toJS (#1581)

    Cursory test is >10% faster than both v3.8.2 and v4.0.0-rc.7, and corrects the regression since v4.0.0-rc.9.

  • Added optional notSetValue in first() and last() (#1556)

  • Make isArrayLike check more precise to avoid false positives (#1520)

  • map() for List, Map, and Set returns itself for no-ops (#1455) (5726bd1)

  • Hash functions as objects, allowing functions as values in collections (#1485)

  • Functional API for get(), set(), and more which support both Immutable.js collections and plain Objects and Arrays (#1369)

  • Relicensed as MIT (#1320)

  • Support for Transducers! (ee9c68f1)

  • Add new method, zipAll() (#1195)

  • Bundle and distribute an "es module" so Webpack and Rollup can use tree-shaking for smaller builds (#1204)

  • Warn instead of throw when getIn() has a bad path (668f2236)

  • A new predicate function isValueObject() helps to detect objects which implement equals() and hashCode(), and type definitions now define the interface ValueObject which you can implement in your own code to create objects which behave as values and can be keys in Maps or entries in Sets.

  • Using fromJS() with a "reviver" function now provides access to the key path to each translated value. (#1118)
