$Id$ Commons Lang Package Version 2.4 Release Notes INTRODUCTION: This document contains the release notes for the 2.4 version of Apache Commons Lang. Commons Lang is a set of utility functions and reusable components that should be of use in any Java environment. INCOMPATIBLE CHANGES WITH VERSION 2.3: - None INCOMPATIBLE CHANGES WITH VERSION 2.2: - Calling stop on a suspended StopWatch will no longer change the underlying time. It's very unlikely anyone was relying on that bug as a feature. ADDITIONAL INCOMPATIBLE CHANGES WITH VERSION 2.0: - The Nestable interface defines the method indexOfThrowable(Class). Previously the implementations checked only for a specific Class. Now they check for subclasses of that Class as well. For most situations this will be the expected behaviour (ie. its a bug fix). If it causes problems, please use the ExceptionUtils.indexOfThrowable(Class) method instead. Note that the ExceptionUtils method is available in v1.0 and v2.0 of commons-lang and has not been changed. (An alternative to this is to change the public static matchSubclasses flag on NestableDelegate. However, we don't recommend that as a long-term solution.) - The StopWatch class has had much extra validation added. If your code previously relied on unusual aspects, it may no longer work. - Starting with version 2.1, Ant version 1.6.x is required to build. Copy junit.jar to ANT_HOME/lib. You can get JUnit from http://www.junit.org. See the developer's guide for more details. DEPRECATIONS FROM 2.3 to 2.4: - ObjectUtils.appendIdentityToString(StringBuffer, Object) - has very odd semantics, use ObjectUtils.identityToString(StringBuffer, Object) instead. - public static java.util.Date add(java.util.Date, int, int) - it is not intended for this method to be public. Please let us know if you use this. DEPRECATIONS FROM 2.2 to 2.3: - None DEPRECATIONS FROM 2.1 to 2.2: - None DEPRECATIONS FROM 2.0 to 2.1: - The enum package has been renamed to enums for JDK1.5 compilance. All functionality is identical, just the package has changed. This package will be removed in v3.0. - NumberUtils.stringToInt - renamed to toInt - DateUtils - four constants, MILLIS_IN_* have been deprecated as they were defined as int not long. The replacements are MILLIS_PER_*.
