<p>

|
|
These are the release notes for Commons Collections v3.2:
|
||
|
|
</p>
|
||

|
<hr />
|
||

<p>
|
||
|
|
Commons collections is a project to develop and maintain collection classes
|
||
|
|
based on and inspired by the JDK collection framework.
|
||
|
|
This project is JDK1.2 compatible, and does not use JDK1.5 generics.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
This release adds various new classes and fixes a number of bugs.
|
||
|
|
All feedback should be directed to commons-user at jakarta.apache.org.
|
||
|
|
</p>
|
||
|

||
|
|
<center><h3>COMPATIBILITY</h3></center>
|
||
|
|
<p>
|
||
|
|
This release is fully source and binary compatible with v3.1.
|
||
|
|
(Checks performed using JDiff and Clirr, thanks).
|
||
|
|
Please check the bug fixes to ensure you weren't relying on the behaviour of a bug.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
There are two new <i>deprecations</i>:<br />
|
||
|
|
BeanMap is now deprecated and will be removed in v4.0.
|
||
|
|
The class is now available in commons-beanutils (full jar version).
|
||
|
|
This change was made to ensure that all bean related collections were in one place (ie. beanutils).
|
||
|
|
If this causes major headaches to anyone please contact commons-dev at jakarta.apache.org.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
MultiHashMap is now deprecated and will be removed in v4.0.
|
||
|
|
The class is now available as MultiValueMap in the map subpackage.
|
||
|
|
This new version of the class is a decorator and can wrap maps other than HashMap
|
||
|
|
making it much more flexible.
|
||
|
|
If this causes major headaches to anyone please contact commons-dev at jakarta.apache.org.
|
||
|
|
