29 June 2004 - Jakarta Commons Collections 3.1 Released

The Jakarta Commons Collections team is pleased to announce the release of Commons Collections 3.1. Commons Collections provides additional interfaces and implementations based on, and inspired by, the Java Collections Framework (Collection, List, Set, Map).

This release fixes a number of bugs in v3.0 and is fully compatible. Release v3.1 is also compatible with v2.1.1 enabling a workaround of previous compatability issues in IteratorUtils. In addition to bug fixes, this release adds various new features including:

• TreeList - A new list implementation that is faster than ArrayList in certain use cases


• MultiKeyMap - A dedicated map implementation to support combined keys mapping to a value


• ReferenceIdentityMap - An identity based map whose keys/values can be garbage collected


• Many more Serializable classes
