Fixed a bug in ImportFromSamePackage; now it catches the case where a class has an on-demand import for the same package it is in.
Fixed a bug in CompareObjectsWithEquals; now it catches some local variable cases.
Fixed a bug in CouplingBetweenObjects; it no longer triggers an exception (which is a bug in the symbol table layer) by calling getEnclosingClassScope() when the node in question isn't enclosed by one.
Moved AvoidCallingFinalize from the design ruleset to the finalize ruleset and then deleted redundant ExplicitCallToFinalize rule from the finalize ruleset.

Harden equality of AbstractRule and RuleSet objects (needed for the Eclipse plugin features)
Change RuleSet.getRuleByName. Now return null instead of throwing a RuntimeException when the rule is not found

Applied patch 1051956 - Rulesets that reference rules using "ref" can now override various properties.

YAHTMLRenderer no longer has dependence on Ant packages.
Modified the AST to correctly include PostfixExpression nodes. Previously a statement like "x++;" was embedded in the parent StatementExpression node.
Moved BooleanInstantiation from the design ruleset to the basic ruleset.
Updated Xerces libraries to v2.6.2.
Many rule names had the word "Rule" tacked on to the end. Various folks thought this was a bad idea, so here are the new names of those rules which were renamed:

- Good article on features: http://java.sun.com/developer/technicalArticles/releases/j2se15/
October 19, 2004 - 2.0:
New rules: InstantiationToGetClass, IdempotentOperationsRule, SuspiciousEqualsMethodName, SimpleDateFormatNeedsLocale, JUnitTestsShouldContainAssertsRule, SuspiciousConstantFieldName, ImmutableFieldRule, MoreThanOneLoggerRule, LoggerIsNotStaticFinalRule, UseLocaleWithCaseConversions
Applied patch in RFE 992576 - Enhancements to VariableNamingConventionsRule
Implemented RFE 995910 - The HTML report can now include links to HTMLlized source code - for example, the HTML generated by JXR.
Implemented RFE 665824 - PMD now ignores rule violations in lines containing the string 'NOPMD'.
Fixed bug in SimplifyBooleanExpressions - now it catches more cases.
Fixed bugs in AvoidDuplicateLiterals - now it ignores small duplicate literals, its message is more helpful, and it catches more cases.
Fixed bug 997893 - UnusedPrivateField now detects assignments to members of private fields as a usage.
Fixed bug 1020199 - UnusedLocalVariable no longer flags arrays as unused if an assignment is made to an array slot.

Applied patch 1032927 - The XML report now includes the rule priority.
Added data flow analysis facade from Raik Schroeder.
Added two new optional attributes to rule definitions - symboltable and dfa. These allow the symbol table and DFA facades to be configured on a rule-by-rule basis. Note that if your rule needs the symbol table; you'll need to add symboltable="true" to your rule definition. FWIW, this also results in about a 5% speedup for rules that don't need either layer.
Added a "logging" ruleset - thanks to Miguel Griffa for the code!
Enhanced the ASTViewer - and renamed it 'Designer' - to display data flows.
Moved development environment to Maven 1.0.
Moved development environment to Ant 1.6.2. This is nice because using the new JUnit task attribute "forkmode='perBatch'" cuts test runtime from 90 seconds to 7 seconds. Sweet.
MethodWithSameNameAsEnclosingClass now reports a more helpful line number.
July 14, 2004 - 1.9:

Moved LooseCoupling from design.xml to coupling.xml.
Some minor performance optimizations - removed some unnecessary casts from the grammar, simplified some XPath rules.
Postfix expressions (i.e., x++) are now available in the grammar. To access them, search for StatementExpressions with an image of "++" or "--" - i.e., in XPath, //StatementExpression[@Image="++"]. This is an odd hack and hopefully will get cleared up later.
Ant task and CLI now used BufferedInputStreams.
Converted AtLeastOneConstructor rule from Java code to XPath.
Implemented RFE 743460: The XML report now contains the ruleset name.
Implemented RFE 958714: Private field and local variables that are assigned but not used are now flagged as unused.
Fixed bug 962782 - BeanMembersShouldSerializeRule no longer reports set/is as being a violation.

Fixed bug 786611 - Expressions are no longer over-expanded in the AST

Implemented RFE 925839 - Added some more detail to the UseSingletonRule.
Added an optional 'failuresPropertyName' attribute to the Ant task.
Refactored away duplicate copies of XPath rule definitions in regress/, yay!
Removed manifest from jar file; it was only there for the Main-class attribute, and it's not very useful now since PMD has several dependencies.
Began working on JDK 1.5 compatibility - added support for EnumDeclaration nodes.
March 15, 2004 - 1.6:
Fixed bug 895661 - XML reports containing error elements no longer have malformed XML.
Fixed a bug in UnconditionalIfStatement - it no longer flags things like "if (x==true)".
