 ### New and noteworthy
 
-#### Java 14 Support
-
-This release of PMD brings support for Java 14. PMD can parse [Switch Expressions](https://openjdk.java.net/jeps/361),
-which have been promoted to be a standard language feature of Java.
-
-PMD also parses [Text Blocks](https://openjdk.java.net/jeps/368) as String literals, which is still a preview
-language feature in Java 14.
-
-The new [Pattern Matching for instanceof](https://openjdk.java.net/jeps/305) can be used as well as
-[Records](https://openjdk.java.net/jeps/359).
-
-Note: The Text Blocks, Pattern Matching for instanceof and Records are all preview language features of OpenJDK 14
-and are not enabled by default. In order to
-analyze a project with PMD that uses these language features, you'll need to enable it via the environment
-variable `PMD_JAVA_OPTS` and select the new language version `14-preview`:
-
-    export PMD_JAVA_OPTS=--enable-preview
-    ./run.sh pmd -language java -version 14-preview ...
-
-Note: Support for the extended break statement introduced in Java 12 as a preview language feature
-has been removed from PMD with this version. The version "12-preview" is no longer available.
-
-
-#### Updated PMD Designer
-
-This PMD release ships a new version of the pmd-designer.
-For the changes, see [PMD Designer Changelog](https://github.com/pmd/pmd-designer/releases/tag/6.21.0).
-
-#### Apex Suppressions
-
-In addition to suppressing violation with the `@SuppressWarnings` annotation, Apex now also supports
-the suppressions with a `NOPMD` comment. See [Suppressing warnings](pmd_userdocs_suppressing_warnings.html).
-
-#### Improved CPD support for C#
-
-The C# tokenizer is now based on an antlr grammar instead of a manual written tokenizer. This
-should give more accurate results and especially fixes the problems with the using statement syntax
-(see [#2139](https://github.com/pmd/pmd/issues/2139)).
-
-#### XPath Rules
-
-See the new documentation about [Writing XPath Rules](pmd_userdocs_extending_writing_xpath_rules.html).
-
-*Note:* As of PMD version 6.22.0, XPath versions 1.0 and the 1.0 compatibility mode are **deprecated**.
-XPath 2.0 is superior in many ways, for example for its support for type checking, sequence values,
-or quantified expressions. For a detailed but approachable review of the features of XPath 2.0 and above,
-see the [Saxon documentation](https://www.saxonica.com/documentation/index.html#!expressions).
-
-#### New Rules
-
-*   The Rule {% rule "apex/design/CognitiveComplexity" %} (`apex-design`) finds methods and classes
-    that are highly complex and therefore difficult to read and more costly to maintain. In contrast
-    to cyclomatic complexity, this rule uses "Cognitive Complexity", which is a measure of how
-    difficult it is for humans to read and understand a method.
-
-*   The Rule {% rule "apex/errorprone/TestMethodsMustBeInTestClasses" %} (`apex-errorprone`) finds test methods
-    that are not residing in a test class. The test methods should be moved to a proper test class.
-    Support for tests inside functional classes was removed in Spring-13 (API Version 27.0), making classes
-    that violate this rule fail compile-time. This rule is however useful when dealing with legacy code.
-

 ### API Changes
 
-#### Deprecated APIs
-
-##### Internal API
-
-Those APIs are not intended to be used by clients, and will be hidden or removed with PMD 7.0.0.
-You can identify them with the `@InternalApi` annotation. You'll also get a deprecation warning.
-
-* {% jdoc java::lang.java.JavaLanguageHandler %}
-* {% jdoc java::lang.java.JavaLanguageParser %}
-* {% jdoc java::lang.java.JavaDataFlowHandler %}
-* Implementations of {% jdoc core::lang.rule.RuleViolationFactory %} in each
-  language module, eg {% jdoc java::lang.java.rule.JavaRuleViolationFactory %}.
-  See javadoc of {% jdoc core::lang.rule.RuleViolationFactory %}.
-* Implementations of {% jdoc core::RuleViolation %} in each language module,
-  eg {% jdoc java::lang.java.rule.JavaRuleViolation %}. See javadoc of
-  {% jdoc core::RuleViolation %}.
-
-* {% jdoc core::rules.RuleFactory %}
-* {% jdoc core::rules.RuleBuilder %}
-* Constructors of {% jdoc core::RuleSetFactory %}, use factory methods from {% jdoc core::RulesetsFactoryUtils %} instead
-* {% jdoc core::RulesetsFactoryUtils#getRulesetFactory(core::PMDConfiguration, core::util.ResourceLoader) %}
-
-* {% jdoc apex::lang.apex.ast.AbstractApexNode %}
-* {% jdoc apex::lang.apex.ast.AbstractApexNodeBase %}, and the related `visit`
-methods on {% jdoc apex::lang.apex.ast.ApexParserVisitor %} and its implementations.
- Use {% jdoc apex::lang.apex.ast.ApexNode %} instead, now considers comments too.
-
-##### For removal
-
-* pmd-core
-  * {% jdoc core::lang.dfa.DFAGraphRule %} and its implementations
-  * {% jdoc core::lang.dfa.DFAGraphMethod %}
-  * Many methods on the {% jdoc core::lang.ast.Node %} interface
-  and {% jdoc core::lang.ast.AbstractNode %} base class. See their javadoc for details.
-  * {% jdoc !!core::lang.ast.Node#isFindBoundary() %} is deprecated for XPath queries.
-  * Many APIs of {% jdoc_package core::lang.metrics %}, though most of them were internal and
-  probably not used directly outside of PMD. Use {% jdoc core::lang.metrics.MetricsUtil %} as
-  a replacement for the language-specific façades too.
-  * {% jdoc core::lang.ast.QualifiableNode %}, {% jdoc core::lang.ast.QualifiedName %}
-* pmd-java

-      {% jdoc java::lang.java.ast.ASTMethodOrConstructorDeclaration %},
-      {% jdoc java::lang.java.ast.ASTLambdaExpression %}.
-  * {% jdoc !!java::lang.java.ast.ASTAnyTypeDeclaration#getImage() %} will be removed. Please use `getSimpleName()`
-    instead. This affects {% jdoc !!java::lang.java.ast.ASTAnnotationTypeDeclaration#getImage() %},
-    {% jdoc !!java::lang.java.ast.ASTClassOrInterfaceDeclaration#getImage() %}, and
-    {% jdoc !!java::lang.java.ast.ASTEnumDeclaration#getImage() %}.
-  * Several methods of {% jdoc java::lang.java.ast.ASTTryStatement %}, replacements with other names
-    have been added. This includes the XPath attribute `@Finally`, replace it with a test for `child::FinallyStatement`.

-    following nodes: WhileStatement, DoStatement, ForStatement, IfStatement, AssertStatement, ConditionalExpression.
-  * {% jdoc java::lang.java.ast.ASTYieldStatement %} will not implement {% jdoc java::lang.java.ast.TypeNode %}
-    anymore come 7.0.0. Test the type of the expression nested within it.
-  * {% jdoc java::lang.java.metrics.JavaMetrics %}, {% jdoc java::lang.java.metrics.JavaMetricsComputer %}
-  * {% jdoc !!java::lang.java.ast.ASTArguments#getArgumentCount() %}.
-    Use {% jdoc java::lang.java.ast.ASTArguments#size() %} instead.
-  * {% jdoc !!java::lang.java.ast.ASTFormalParameters#getParameterCount() %}.
-    Use {% jdoc java::lang.java.ast.ASTFormalParameters#size() %} instead.
-* pmd-apex
-  * {% jdoc apex::lang.apex.metrics.ApexMetrics %}, {% jdoc apex::lang.apex.metrics.ApexMetricsComputer %}
-
-##### In ASTs (JSP)
-
-As part of the changes we'd like to do to AST classes for 7.0.0, we would like to
-hide some methods and constructors that rule writers should not have access to.
-The following usages are now deprecated **in the JSP AST** (with other languages to come):
-
-*   Manual instantiation of nodes. **Constructors of node classes are deprecated** and
-    marked {% jdoc core::annotation.InternalApi %}. Nodes should only be obtained from the parser,
-    which for rules, means that they never need to instantiate node themselves.
-    Those constructors will be made package private with 7.0.0.
-*   **Subclassing of abstract node classes, or usage of their type**. The base classes are internal API
-    and will be hidden in version 7.0.0. You should not couple your code to them.
-    *   In the meantime you should use interfaces like {% jdoc jsp::lang.jsp.ast.JspNode %} or
-        {% jdoc core::lang.ast.Node %}, or the other published interfaces in this package,
-        to refer to nodes generically.
-    *   Concrete node classes will **be made final** with 7.0.0.
-*   Setters found in any node class or interface. **Rules should consider the AST immutable**.
-    We will make those setters package private with 7.0.0.
-*   The class {% jdoc jsp::lang.jsp.JspParser %} is deprecated and should not be used directly.
-    Use {% jdoc !!core::lang.LanguageVersionHandler#getParser(ParserOptions) %} instead.
-
-Please look at {% jdoc_package jsp::lang.jsp.ast %} to find out the full list of deprecations.
-
-##### In ASTs (Velocity)
-
-As part of the changes we'd like to do to AST classes for 7.0.0, we would like to
-hide some methods and constructors that rule writers should not have access to.
-The following usages are now deprecated **in the VM AST** (with other languages to come):
-
-*   Manual instantiation of nodes. **Constructors of node classes are deprecated** and
-    marked {% jdoc core::annotation.InternalApi %}. Nodes should only be obtained from the parser,
-    which for rules, means that they never need to instantiate node themselves.
-    Those constructors will be made package private with 7.0.0.
-*   **Subclassing of abstract node classes, or usage of their type**. The base classes are internal API
-    and will be hidden in version 7.0.0. You should not couple your code to them.
-    *   In the meantime you should use interfaces like {% jdoc vm::lang.vm.ast.VmNode %} or
-        {% jdoc core::lang.ast.Node %}, or the other published interfaces in this package,
-        to refer to nodes generically.
-    *   Concrete node classes will **be made final** with 7.0.0.
-*   Setters found in any node class or interface. **Rules should consider the AST immutable**.
-    We will make those setters package private with 7.0.0.
-*   The package {% jdoc_package vm::lang.vm.directive %} as well as the classes
-    {% jdoc vm::lang.vm.util.DirectiveMapper %} and {% jdoc vm::lang.vm.util.LogUtil %} are deprecated
-    for removal. They were only used internally during parsing.
-*   The class {% jdoc vm::lang.vm.VmParser %} is deprecated and should not be used directly.
-    Use {% jdoc !!core::lang.LanguageVersionHandler#getParser(ParserOptions) %} instead.
-
-Please look at {% jdoc_package vm::lang.vm.ast %} to find out the full list of deprecations.
-
-#### PLSQL AST
-
-The production and node `ASTCursorBody` was unnecessary, not used and has been removed. Cursors have been already
-parsed as `ASTCursorSpecification`.

+
+This release of PMD brings support for Java 14. PMD can parse [Switch Expressions](https://openjdk.java.net/jeps/361),
+which have been promoted to be a standard language feature of Java.
+
+PMD also parses [Text Blocks](https://openjdk.java.net/jeps/368) as String literals, which is still a preview

+
+The new [Pattern Matching for instanceof](https://openjdk.java.net/jeps/305) can be used as well as

+
+This PMD release ships a new version of the pmd-designer.
+For the changes, see [PMD Designer Changelog](https://github.com/pmd/pmd-designer/releases/tag/6.21.0).
+
+#### Apex Suppressions
+
+In addition to suppressing violation with the `@SuppressWarnings` annotation, Apex now also supports

+See the new documentation about [Writing XPath Rules](pmd_userdocs_extending_writing_xpath_rules.html).
+
+*Note:* As of PMD version 6.22.0, XPath versions 1.0 and the 1.0 compatibility mode are **deprecated**.

+
+#### New Rules
+
+*   The Rule [`CognitiveComplexity`](https://pmd.github.io/pmd-6.22.0/pmd_rules_apex_design.html#cognitivecomplexity) (`apex-design`) finds methods and classes
+    that are highly complex and therefore difficult to read and more costly to maintain. In contrast
+    to cyclomatic complexity, this rule uses "Cognitive Complexity", which is a measure of how
+    difficult it is for humans to read and understand a method.
+
+*   The Rule [`TestMethodsMustBeInTestClasses`](https://pmd.github.io/pmd-6.22.0/pmd_rules_apex_errorprone.html#testmethodsmustbeintestclasses) (`apex-errorprone`) finds test methods
+    that are not residing in a test class. The test methods should be moved to a proper test class.
+    Support for tests inside functional classes was removed in Spring-13 (API Version 27.0), making classes
+    that violate this rule fail compile-time. This rule is however useful when dealing with legacy code.

+##### In ASTs (JSP)
+
+As part of the changes we'd like to do to AST classes for 7.0.0, we would like to
+hide some methods and constructors that rule writers should not have access to.
+The following usages are now deprecated **in the JSP AST** (with other languages to come):
+
+*   Manual instantiation of nodes. **Constructors of node classes are deprecated** and
+    marked <a href="https://javadoc.io/page/net.sourceforge.pmd/pmd-core/6.22.0/net/sourceforge/pmd/annotation/InternalApi.html#"><code>InternalApi</code></a>. Nodes should only be obtained from the parser,
+    which for rules, means that they never need to instantiate node themselves.
+    Those constructors will be made package private with 7.0.0.
+*   **Subclassing of abstract node classes, or usage of their type**. The base classes are internal API
+    and will be hidden in version 7.0.0. You should not couple your code to them.
+    *   In the meantime you should use interfaces like <a href="https://javadoc.io/page/net.sourceforge.pmd/pmd-jsp/6.22.0/net/sourceforge/pmd/lang/jsp/ast/JspNode.html#"><code>JspNode</code></a> or
+        <a href="https://javadoc.io/page/net.sourceforge.pmd/pmd-core/6.22.0/net/sourceforge/pmd/lang/ast/Node.html#"><code>Node</code></a>, or the other published interfaces in this package,
+        to refer to nodes generically.
+    *   Concrete node classes will **be made final** with 7.0.0.
+*   Setters found in any node class or interface. **Rules should consider the AST immutable**.
+    We will make those setters package private with 7.0.0.
+*   The class <a href="https://javadoc.io/page/net.sourceforge.pmd/pmd-jsp/6.22.0/net/sourceforge/pmd/lang/jsp/JspParser.html#"><code>JspParser</code></a> is deprecated and should not be used directly.
+    Use <a href="https://javadoc.io/page/net.sourceforge.pmd/pmd-core/6.22.0/net/sourceforge/pmd/lang/LanguageVersionHandler.html#getParser(ParserOptions)"><code>LanguageVersionHandler#getParser</code></a> instead.
+
+Please look at <a href="https://javadoc.io/page/net.sourceforge.pmd/pmd-jsp/6.22.0/net/sourceforge/pmd/lang/jsp/ast/package-summary.html#"><code>net.sourceforge.pmd.lang.jsp.ast</code></a> to find out the full list of deprecations.

+##### In ASTs (Velocity)
+
+As part of the changes we'd like to do to AST classes for 7.0.0, we would like to

+    for removal. They were only used internally during parsing.
+*   The class <a href="https://javadoc.io/page/net.sourceforge.pmd/pmd-vm/6.22.0/net/sourceforge/pmd/lang/vm/VmParser.html#"><code>VmParser</code></a> is deprecated and should not be used directly.
