May, 1, 2012 - 5.0.0:
Fixed bug 3470274: Using Label for lines in XMLRenderer
Fixed bug 3175710: NPE in InsufficientStringBufferDeclaration
CPD:
- Exit with status code 4 when CPD detects code duplication (Patch ID: 3497021)
January 31, 2012 - 5.0-alpha:
This version of PMD breaks API compatibility with prior versions of PMD, as well
as RuleSet XML compatibility. Also the maven coordinates (groupId) have been changed.
The decision to break compatibility, allows PMD
internals and code organization to be improved to better handle additional
languages. This opportunity was used to remove depreciated APIs, and beat up
any code which has thumbed its nose at the developers over the years. ;)
The following is relatively complete list of the major changes (this may not be
100% accurate, see actual source code when in doubt):
Fixed bug (no number) - Fixed UseStringBufferLengthRule only worked once per class
All StringBuffer-related rules now also catch StringBuilder-related issues in the same way

New features:
New Language 'ecmascript' added, for writing XPathRule and Java Rules against ECMAScript/JavaScript documents (must be standalone, not embedded in HTML). Many thanks to Rhino!
New Language 'xml' added, for writing XPathRules against XML documents
New Language 'xsl' added, as a derivative from XML.
Rules can now define a 'violationSuppressRegex' property to universally suppress violations with messages matching the given regular expression
Rules can now define a 'violationSuppressXPath' property to universally suppress violations on nodes which match the given relative XPath expression
Rules are now directly associated with a corresponding Language, and a can also be associated with a specific Language Version range if desired.
Rules can now be flagged with deprecated='true' in the RuleSet XML to allow the PMD Project to indicate a Rule (1) is scheduled for removal, (2) has been removed, or (3) has been renamed/moved.
XPathRules can now query using XPath 2.0 with 'version=2.0"', or XPath 2.0 in XPath 1.0 compatibility mode using 'version="1.0 compatibility"'. Many thanks to Saxon!
Rules can now use property values in messages, for example ${propertyName} will expand to the value of the 'propertyName' property on the Rule.
Rules can now use violation specific values in messages, specifically ${variableName}, ${methodName}, ${className}, ${packageName}.
New XPath function 'getCommentOn' can be used to search for strings in comments - Thanks to Andy Throgmorton

Other changes:
Rule property API upgrades:
All numeric property descriptors can specify upper & lower limits
Newly functional Method & Type descriptors allow rule developers to incorporate/watch for individual methods or types
Better initialization error detection
Deprecated old string-keyed property API, will leave some methods behind for XPath rules however
'41' and '42' shortcuts for rulesets added
The default Java version processed by PMD is now uniformly Java 1.5.

TokenManager errors now include a file name whenever possible for every AST in PMD
Added file encoding option to CPD GUI, which already existed for the command line and Ant
AssignmentInOperand enhanced to catch assignment in 'for' condition, as well as use of increment/decrement operators. Customization properties added to allow assignment in if/while/for, or use of increment/decrement.
Fix false positive on CastExpressions for UselessParentheses
Fix false positive where StringBuffer.setLength(0) was using default constructor size of 16, instead of actual constructor size.
Fix false negative for non-primitive types for VariableNamingConventions, also expanded scope to local and method/constructors, and enhanced customization options to choose between members/locals/parameters (all checked by default)
