# Changelog
## February 11, 2014 - 5.1.0:
**New/Updated Languages:**
- Java 1.8 support added.
- PLSQL support added; thanks to Stuart Turton. See also http://pldoc.sourceforge.net/
- Apache Velocity support added; thanks to Andrey Utis. See also http://velocity.apache.org
**New/Updated Rulesets and Rules:**
- EcmaScript
- Controversial ruleset, featuring AvoidWithStatement
- UseBaseWithParseInt
- Java
- GuardLogStatement
- replace xpath implementation of GuardDebugLogging by GuardLogStatement (better perf)
- CommentRequired
- basic rule to check for existence for formal (javadoc) comments.
- AvoidProtectedMethodInFinalClassNotExtending
- rule to avoid protected methods in final classes that don't extend anything other than Object.
- ConsecutiveAppendsShouldReuse
- rule to encourage to reuse StringBuilder.append returned object for consecutive calls.
- PositionLiteralsFirstInCaseInsensitiveComparisons
- rule similar to PositionLiteralsFirstInComparisons, but for case insensitive comparisons (equalsIgnoreCase).
Thanks to Larry Diamond
- ConfusingTernary
- new property "ignoreElseIf" to suppress this rule in case of if-else-if-else usage.
See [feature 1161]: Confusing Ternary should skip else if statements (or have a property to do so)
- FieldDeclarationsShouldBeAtStartOfClass
- new property "ignoreEnumDeclarations" which is enabled by default. This relaxes the rule, so
that enums can be declared before fields and the rule is not triggered.
