Commons Collections
[http://jakarta.apache.org/commons/collections Collections] aims to provide:
- New implementations of the JDK Collection, Set, List and Map interfaces
- Additional related collection interfaces and implementations
- Abstract base classes to simplify the writing of new implementations
- A testing framework, as a published jar, that excercises the API fully
The Javadoc of the latest version is [http://jakarta.apache.org/commons/collections/apidocs-COLLECTIONS_3_0/index.html available].

Releases & Compatability
The latest release (v3.0) can be downloaded [http://jakarta.apache.org/commons/collections/index.html#Releases here].
Two releases of Collections are currently in common use - v2.1 and v3.0. These releases are source compatible (with deprecations). Unfortunately, due to human error, these releases are binary incompatible in the IteratorUtils class. If you don't use this class, then the two versions are binary compatible.
Feedback
Release v3.1 is currently under active development. You can give feedback on what you would ilke included by contacting the commons-dev@jakarta.apache.org mailing list, prefixing you email by [collections]. Alternatively add a comment here:
