4.7.0

New sniffs:

• ModernClassNameReferenceSniff: Reports use of __CLASS__, get_parent_class(), get_called_class(), get_class() and get_class($this). Class names should be referenced via ::class contant when possible
• StaticClosureSniff: Reports closures not using $this that are not declared static
• RequireCombinedAssignmentOperatorSniff: Requires using combined assigment operators, eg +=, .= etc
• NullTypeHintOnLastPositionSniff: Enforces null type hint on last position in @var, @param and @return annotations
• UselessConstantTypeHint: Reports useless @var annotation (or whole documentation comment) for class constants because the type of constant is always clear
• UselessInheritDocCommentSniff: Reports documentation comments containing only {@inheritDoc} annotation because inheritance is automatic and it's not needed to use a special annotation for it
• TraitUseDeclarationSniff: Prohibits multiple traits separated by commas in one use statement
• TraitUseSpacingSniff: Enforces configurable number of lines before first use, after last use and between two use statements
• UnusedVariableSniff: Looks for unused variables
• UselessVariableSniff: Looks for useless variables
• UnusedParameterSniff: Looks for unused parameters
• UnusedInheritedVariablePassedToClosureSniff: Looks for unused inherited variables passed to closure via use
• UselessAliasSniff: Looks for use alias that is same as unqualified name
• UselessSemicolonSniff: Looks for useless semicolons
• UselessParenthesesSniff: Looks for useless parentheses
• NewWithoutParenthesesSniff: Reports new with useless parentheses

Improvements:

• RequireNullCoalesceOperatorSniff: === null and !== null conditions are detected too
• RequireShortTernaryOperatorSniff: Works with properties too

Fixes:

• UnusedUsesSniff: Fixed false positives for classes used in @see annotation
• FullyQualifiedClassNameInAnnotationSniff: Fixed fixer
• NamespaceSpacingSniff: Fixed false positive when phpcs comment is before namespace
