### New and noteworthy
#### Updated Apex Support
* The Apex language support has been bumped to version 45 (Spring '19). All new language features are now properly
parsed and processed.
* Many nodes now expose more informations, such as the operator for BooleanExpressions. This makes these operators
consumable by XPath rules, e.g. `//BooleanExpression[@Operator='&&']`.
#### PL/SQL Grammar improvements
* In this release, many parser bugs in our PL/SQL support have been fixed. This adds e.g. support for
table collection expressions (`SELECT * FROM TABLE(expr)`).
* Support for parsing insert statements has been added.
* More improvements are planned for the next release of PMD.
#### New Rules
* The new Java rule {% rule "java/multithreading/UnsynchronizedStaticFormatter" %} (`java-multithreading`) detects
unsynchronized usages of static `java.text.Format` instances. This rule is a more generic replacement of the
rule {% rule "java/multithreading/UnsynchronizedStaticDateFormatter" %} which focused just on `DateFormat`.
* The new Java rule {% rule "java/bestpractices/ForLoopVariableCount" %} (`java-bestpractices`) checks for
the number of control variables in a for-loop. Having a lot of control variables makes it harder to understand
what the loop does. The maximum allowed number of variables is by default 1 and can be configured by a
property.
* The new Java rule {% rule "java/bestpractices/AvoidReassigningLoopVariables" %} (`java-bestpractices`) searches
for loop variables that are reassigned. Changing the loop variables additionally to the loop itself can lead to
hard-to-find bugs.
* The new Java rule {% rule "java/codestyle/UseDiamondOperator" %} (`java-codestyle`) looks for constructor
calls with explicit type parameters. Since Java 1.7, these type parameters are not necessary anymore, as they
can be inferred now.
#### Modified Rules
* The Java rule {% rule "java/codestyle/LocalVariableCouldBeFinal" %} (`java-codestyle`) has a new
property `ignoreForEachDecl`, which is by default disabled. The new property allows for ignoring
non-final loop variables in a for-each statement.
#### Deprecated Rules
* The Java rule {% rule "java/multithreading/UnsynchronizedStaticDateFormatter" %} has been deprecated and
will be removed with PMD 7.0.0. The rule is replaced by the more general
{% rule "java/multithreading/UnsynchronizedStaticFormatter" %}.

### API Changes
* {% jdoc core::lang.rule.stat.StatisticalRule %} and the related helper classes and base rule classes
are deprecated for removal in 7.0.0. This includes all of {% jdoc_package core::stat %} and {% jdoc_package core::lang.rule.stat %},
and also {% jdoc java::lang.java.rule.AbstractStatisticalJavaRule %}, {% jdoc apex::lang.apex.rule.AbstractStatisticalApexRule %} and the like.
The methods {% jdoc !c!core::Report#addMetric(core::stat.Metric) %} and {% jdoc core::ThreadSafeReportListener#metricAdded(core::stat.Metric) %}
will also be removed.
* {% jdoc core::properties.PropertySource#setProperty(core::properties.MultiValuePropertyDescriptor, Object[]) %} is deprecated,
because {% jdoc core::properties.MultiValuePropertyDescriptor %} is deprecated as well

unsynchronized usages of static `java.text.Format` instances. This rule is a more generic replacement of the

are deprecated for removal in 7.0.0.

The methods [`Report#addMetric`](https://javadoc.io/page/net.sourceforge.pmd/pmd-core/6.11.0/net/sourceforge/pmd/Report.html#addMetric(net.sourceforge.pmd.stat.Metric)) and [`metricAdded`](https://javadoc.io/page/net.sourceforge.pmd/pmd-core/6.11.0/net/sourceforge/pmd/ThreadSafeReportListener.html#metricAdded(net.sourceforge.pmd.stat.Metric))
will also be removed.
* [`setProperty`](https://javadoc.io/page/net.sourceforge.pmd/pmd-core/6.11.0/net/sourceforge/pmd/properties/PropertySource.html#setProperty(net.sourceforge.pmd.properties.MultiValuePropertyDescriptor,Object[])) is deprecated,
