 ======
 
 Quiver is a set of utility libraries for Dart that makes using many Dart
 libraries easier and more convenient, or adds additional functionality.

 ## Documentation
 
 [API Docs](http://www.dartdocs.org/documentation/quiver/latest) are available.
 
 ## Installation
 
 Add Quiver to your project's pubspec.yaml file and run `pub get`.
 We recommend the following version constraint:
 
     dependencies:
-      quiver: '>=0.21.0<0.22.0'
+      quiver: '>=0.25.0<0.26.0'
 
 # Main Libraries
 
 ## [quiver.async][]
 
 Utilities for working with Futures, Streams and async computations.
 
+`collect` collects the completion events of an `Iterable` of `Future`s into a
+`Stream`.
+
+`enumerate` and `concat` represent `Stream` versions of the same-named
+[quiver.iterables][] methods.
+
+`doWhileAsync`, `reduceAsync` and `forEachAsync` perform async computations on
+the elements of on Iterables, waiting for the computation to complete before
+processing the next element.
+
+`StreamBuffer` allows for the orderly reading of elements from a stream, such
+as a socket.
+
 `FutureGroup` is collection of Futures that signals when all its child futures
 have completed. Allows adding new Futures as long as it hasn't completed yet.
 Useful when async tasks can spwn new async tasks and you need to wait for all of
 them to complete.
 
 `FutureStream` turns a `Future<Stream>` into a `Stream` which emits the same
 events as the stream returned from the future.
 
 `StreamRouter` splits a Stream into mulltiple streams based on a set of
 predicates.
 
 `CountdownTimer` is a simple countdown timer that fires events in regular
 increments.
 
-`doWhileAsync`, `reduceAsync` and `forEachAsync` perform async computations on
-the elements of on Iterables, waiting for the computation to complete before
-processing the next element.
-
 `CreateTimer` and `CreateTimerPeriodic` are typedefs that are useful for
 passing Timer factories to classes and functions, increasing the testability of
 code that depends on Timer.
 
 `Metronome` is a self-correcting alternative to `Timer.periodic`. It provides
 a simple, tracking periodic stream of `DateTime` events with optional anchor
 time.

 `matchesAny` combines multiple Patterns into one, and allows for exclusions.
 
 `matchesFull` returns true if a Pattern matches an entire String.
 
 `escapeRegex` escapes special regex characters in a String so that it can be
 used as a literal match inside of a RegExp.

 ## [quiver.strings][]
 
 `isBlank` checks if a string is `null`, empty or made of whitespace characters.
 
 `isEmpty` checks if a string is `null` or empty.
 
 `equalsIgnoreCase` checks if two strings are equal, ignoring case.
 
 `compareIgnoreCase` compares two strings, ignoring case.

 `assertCheckedMode` asserts the current runtime has checked mode enabled.

 ## [quiver.testing.time][]
 
 `FakeStopwatch` is a Stopwatch that uses a provided `now()` function to get the
 current time.
