<p>We’re excited to bring you the next major version of PMD!</p>
<p>Since this is a big release, we provide here only a concise version of the release notes. We prepared a separate
page with the full <a href="pmd_release_notes_pmd7.html">Detailed Release Notes for PMD 7.0.0</a>.</p>
<div style="border: 1px solid; border-radius: .25rem; padding: .75rem 1.25rem;" role="alert">
<strong>ℹ️ Release Candidates</strong>
<p>PMD 7.0.0 is finally almost ready. In order to gather feedback, we are going to ship a couple of release candidates.
These are officially available on GitHub and Maven Central and can be used as usual (e.g. as a dependency).
We encourage you to try out the new features, but keep in mind that we may introduce API breaking changes between
the release candidates. It should be stable enough if you don't use custom rules.</p>
<p>We have still some tasks planned for the next release candidates.
You can see the progress in <a href="https://github.com/pmd/pmd/issues/3898">PMD 7 Tracking Issue #3898</a>.</p>
<p>If you find any problem or difficulty while updating from PMD 6, please provide feedback via our
<a href="https://github.com/pmd/pmd/issues/new/choose">issue tracker</a>. That way we can improve the experience
for all.</p>

<h3 id="changes-since-700-rc2">Changes since 7.0.0-rc2</h3>
<p>This section lists the most important changes from the last release candidate.
The remaining section describes the complete release notes for 7.0.0.</p>
<h4 id="new-cpd-report-format-cpdhtml-v2xslt">New CPD report format cpdhtml-v2.xslt</h4>
<p>Thanks to @mohan-chinnappan-n a new CPD report format has been added which features a data table.
It uses an XSLT stylesheet to convert CPD’s XML format into HTML.</p>
<p>See <a href="report-examples/cpdhtml-v2.html">the example report</a>.</p>

<h4 id="api-changes">API Changes</h4>
<ul>
<li>The following previously deprecated classes have been removed:

<li>pmd-core
<ul>
<li><code class="language-plaintext highlighter-rouge">net.sourceforge.pmd.PMD</code></li>
<li><code class="language-plaintext highlighter-rouge">net.sourceforge.pmd.cli.PMDCommandLineInterface</code></li>

<li><code class="language-plaintext highlighter-rouge">net.sourceforge.pmd.cli.PmdParametersParseResult</code></li>
</ul>
</li>
</ul>
</li>
<li>
<p>The asset filenames of PMD on <a href="https://github.com/pmd/pmd/releases">GitHub Releases</a> are
now <code class="language-plaintext highlighter-rouge">pmd-dist-&lt;version&gt;-bin.zip</code>, <code class="language-plaintext highlighter-rouge">pmd-dist-&lt;version&gt;-src.zip</code> and <code class="language-plaintext highlighter-rouge">pmd-dist-&lt;version&gt;-doc.zip</code>.
Keep that in mind, if you have an automated download script.</p>
<p>The structure inside the ZIP files stay the same, e.g. we still provide inside the binary distribution
ZIP file the base directory <code class="language-plaintext highlighter-rouge">pmd-bin-&lt;version&gt;</code>.</p>
</li>
<li>The CLI option <code class="language-plaintext highlighter-rouge">--stress</code> (or <code class="language-plaintext highlighter-rouge">-stress</code>) has been removed without replacement.</li>
<li>The CLI option <code class="language-plaintext highlighter-rouge">--minimum-priority</code> was changed with 7.0.0-rc1 to only take the following values:
High, Medium High, Medium, Medium Low, Low. With 7.0.0-rc2 compatibility has been restored, so that the equivalent
integer values (1 to 5) are supported as well.</li>

</ul>
<h4 id="changed-rules">Changed Rules</h4>
<p><strong>General changes</strong></p>
<ul>
<li>All statistical rules (like ExcessiveClassLength, ExcessiveParameterList) have been simplified and unified.
The properties <code class="language-plaintext highlighter-rouge">topscore</code> and <code class="language-plaintext highlighter-rouge">sigma</code> have been removed. The property <code class="language-plaintext highlighter-rouge">minimum</code> is still there, however the type is not
a decimal number anymore but has been changed to an integer. This affects rules in the languages Apex, Java, PLSQL
and Velocity Template Language (vm):
<ul>
<li>Apex: <a href="pmd_rules_apex_design.html#excessiveclasslength"><code class="language-plaintext highlighter-rouge">ExcessiveClassLength</code></a>, <a href="pmd_rules_apex_design.html#excessiveparameterlist"><code class="language-plaintext highlighter-rouge">ExcessiveParameterList</code></a>,
<a href="pmd_rules_apex_design.html#excessivepubliccount"><code class="language-plaintext highlighter-rouge">ExcessivePublicCount</code></a>, <a href="pmd_rules_apex_design.html#ncssconstructorcount"><code class="language-plaintext highlighter-rouge">NcssConstructorCount</code></a>,
<a href="pmd_rules_apex_design.html#ncssmethodcount"><code class="language-plaintext highlighter-rouge">NcssMethodCount</code></a>, <a href="pmd_rules_apex_design.html#ncsstypecount"><code class="language-plaintext highlighter-rouge">NcssTypeCount</code></a></li>
<li>Java: <a href="pmd_rules_java_design.html#excessiveimports"><code class="language-plaintext highlighter-rouge">ExcessiveImports</code></a>, <a href="pmd_rules_java_design.html#excessiveparameterlist"><code class="language-plaintext highlighter-rouge">ExcessiveParameterList</code></a>,
<a href="pmd_rules_java_design.html#excessivepubliccount"><code class="language-plaintext highlighter-rouge">ExcessivePublicCount</code></a>, <a href="pmd_rules_java_design.html#switchdensity"><code class="language-plaintext highlighter-rouge">SwitchDensity</code></a></li>
<li>PLSQL: <a href="pmd_rules_plsql_design.html#excessivemethodlength"><code class="language-plaintext highlighter-rouge">ExcessiveMethodLength</code></a>, <a href="pmd_rules_plsql_design.html#excessiveobjectlength"><code class="language-plaintext highlighter-rouge">ExcessiveObjectLength</code></a>,
<a href="pmd_rules_plsql_design.html#excessivepackagebodylength"><code class="language-plaintext highlighter-rouge">ExcessivePackageBodyLength</code></a>, <a href="pmd_rules_plsql_design.html#excessivepackagespecificationlength"><code class="language-plaintext highlighter-rouge">ExcessivePackageSpecificationLength</code></a>,
<a href="pmd_rules_plsql_design.html#excessiveparameterlist"><code class="language-plaintext highlighter-rouge">ExcessiveParameterList</code></a>, <a href="pmd_rules_plsql_design.html#excessivetypelength"><code class="language-plaintext highlighter-rouge">ExcessiveTypeLength</code></a>,
<a href="pmd_rules_plsql_design.html#ncssmethodcount"><code class="language-plaintext highlighter-rouge">NcssMethodCount</code></a>, <a href="pmd_rules_plsql_design.html#ncssobjectcount"><code class="language-plaintext highlighter-rouge">NcssObjectCount</code></a>,
<a href="pmd_rules_plsql_design.html#npathcomplexity"><code class="language-plaintext highlighter-rouge">NPathComplexity</code></a></li>
<li>VM: <a href="pmd_rules_vm_design.html#excessivetemplatelength"><code class="language-plaintext highlighter-rouge">ExcessiveTemplateLength</code></a></li>
</ul>
</li>
<li>The general property <code class="language-plaintext highlighter-rouge">violationSuppressXPath</code> which is available for all rules to
<a href="pmd_userdocs_suppressing_warnings.html">suppress warnings</a> now uses XPath version 3.1 by default.
This version of the XPath language is mostly identical to XPath 2.0. In PMD 6, XPath 1.0 has been used.
If you upgrade from PMD 6, you need to verify your <code class="language-plaintext highlighter-rouge">violationSuppressXPath</code> properties.</li>
</ul>
<p><strong>Apex General changes</strong></p>
<ul>
<li>The properties <code class="language-plaintext highlighter-rouge">cc_categories</code>, <code class="language-plaintext highlighter-rouge">cc_remediation_points_multiplier</code>, <code class="language-plaintext highlighter-rouge">cc_block_highlighting</code> have been removed
from all rules. These properties have been deprecated since PMD 6.13.0.
See <a href="https://github.com/pmd/pmd/issues/1648">issue #1648</a> for more details.</li>
</ul>
<p><strong>Java General changes</strong></p>
<ul>
<li>
<p>Violations reported on methods or classes previously reported the line range of the entire method
or class. With PMD 7.0.0, the reported location is now just the identifier of the method or class.
This affects various rules, e.g. <a href="pmd_rules_java_design.html#cognitivecomplexity"><code class="language-plaintext highlighter-rouge">CognitiveComplexity</code></a>.</p>
<p>The report location is controlled by the overrides of the method <a href="https://docs.pmd-code.org/apidocs/pmd-core/7.0.0-SNAPSHOT/net/sourceforge/pmd/lang/ast/Node.html#getReportLocation()"><code>getReportLocation</code></a>
in different node types.</p>
<p>See <a href="https://github.com/pmd/pmd/issues/4439">issue #4439</a> and <a href="https://github.com/pmd/pmd/issues/730">issue #730</a>
for more details.</p>
</li>
</ul>
<p><strong>Java Best Practices</strong></p>
<ul>
<li><a href="pmd_rules_java_bestpractices.html#arrayisstoreddirectly"><code class="language-plaintext highlighter-rouge">ArrayIsStoredDirectly</code></a>: Violations are now reported on the assignment and not
anymore on the formal parameter. The reported line numbers will probably move.</li>
<li><a href="pmd_rules_java_bestpractices.html#avoidreassigningloopvariables"><code class="language-plaintext highlighter-rouge">AvoidReassigningLoopVariables</code></a>: This rule might not report anymore all
reassignments of the control variable in for-loops when the property <code class="language-plaintext highlighter-rouge">forReassign</code> is set to <code class="language-plaintext highlighter-rouge">skip</code>.
See <a href="https://github.com/pmd/pmd/issues/4500">issue #4500</a> for more details.</li>
<li><a href="pmd_rules_java_bestpractices.html#loosecoupling"><code class="language-plaintext highlighter-rouge">LooseCoupling</code></a>: The rule has a new property to allow some types to be coupled
to (<code class="language-plaintext highlighter-rouge">allowedTypes</code>).</li>
<li><a href="pmd_rules_java_bestpractices.html#unusedlocalvariable"><code class="language-plaintext highlighter-rouge">UnusedLocalVariable</code></a>: This rule has some important false-negatives fixed
and finds many more cases now. For details see issues <a href="https://github.com/pmd/pmd/issues/2130">#2130</a>,
<a href="https://github.com/pmd/pmd/issues/4516">#4516</a>, and <a href="https://github.com/pmd/pmd/issues/4517">#4517</a>.</li>
</ul>
<p><strong>Java Codestyle</strong></p>
<ul>
<li><a href="pmd_rules_java_codestyle.html#methodnamingconventions"><code class="language-plaintext highlighter-rouge">MethodNamingConventions</code></a>: The property <code class="language-plaintext highlighter-rouge">checkNativeMethods</code> has been removed. The
property was deprecated since PMD 6.3.0. Use the property <code class="language-plaintext highlighter-rouge">nativePattern</code> to control whether native methods
should be considered or not.</li>
<li><a href="pmd_rules_java_codestyle.html#shortvariable"><code class="language-plaintext highlighter-rouge">ShortVariable</code></a>: This rule now also reports short enum constant names.</li>
<li><a href="pmd_rules_java_codestyle.html#usediamondoperator"><code class="language-plaintext highlighter-rouge">UseDiamondOperator</code></a>: The property <code class="language-plaintext highlighter-rouge">java7Compatibility</code> has been removed. The rule now
handles Java 7 properly without a property.</li>
<li><a href="pmd_rules_java_codestyle.html#unnecessaryfullyqualifiedname"><code class="language-plaintext highlighter-rouge">UnnecessaryFullyQualifiedName</code></a>: The rule has two new properties,
to selectively disable reporting on static field and method qualifiers. The rule also has been improved
to be more precise.</li>
<li><a href="pmd_rules_java_codestyle.html#uselessparentheses"><code class="language-plaintext highlighter-rouge">UselessParentheses</code></a>: The rule has two new properties which control how strict
the rule should be applied. With <code class="language-plaintext highlighter-rouge">ignoreClarifying</code> (default: true) parentheses that are strictly speaking
not necessary are allowed, if they separate expressions of different precedence.
The other property <code class="language-plaintext highlighter-rouge">ignoreBalancing</code> (default: true) is similar, in that it allows parentheses that help
reading and understanding the expressions.</li>
</ul>
<p><strong>Java Design</strong></p>
<ul>
<li><a href="pmd_rules_java_design.html#cyclomaticcomplexity"><code class="language-plaintext highlighter-rouge">CyclomaticComplexity</code></a>: The property <code class="language-plaintext highlighter-rouge">reportLevel</code> has been removed. The property was
deprecated since PMD 6.0.0. The report level can now be configured separated for classes and methods using
<code class="language-plaintext highlighter-rouge">classReportLevel</code> and <code class="language-plaintext highlighter-rouge">methodReportLevel</code> instead.</li>
<li><a href="pmd_rules_java_design.html#immutablefield"><code class="language-plaintext highlighter-rouge">ImmutableField</code></a>: The property <code class="language-plaintext highlighter-rouge">ignoredAnnotations</code> has been removed. The property was
deprecated since PMD 6.52.0.</li>
<li><a href="pmd_rules_java_design.html#lawofdemeter"><code class="language-plaintext highlighter-rouge">LawOfDemeter</code></a>: The rule has a new property <code class="language-plaintext highlighter-rouge">trustRadius</code>. This defines the maximum degree
of trusted data. The default of 1 is the most restrictive.</li>
<li><a href="pmd_rules_java_design.html#npathcomplexity"><code class="language-plaintext highlighter-rouge">NPathComplexity</code></a>: The property <code class="language-plaintext highlighter-rouge">minimum</code> has been removed. It was deprecated since PMD 6.0.0.
Use the property <code class="language-plaintext highlighter-rouge">reportLevel</code> instead.</li>
<li><a href="pmd_rules_java_design.html#singularfield"><code class="language-plaintext highlighter-rouge">SingularField</code></a>: The properties <code class="language-plaintext highlighter-rouge">checkInnerClasses</code> and <code class="language-plaintext highlighter-rouge">disallowNotAssignment</code> have been removed.
The rule is now more precise and will check these cases properly.</li>
<li><a href="pmd_rules_java_design.html#useutilityclass"><code class="language-plaintext highlighter-rouge">UseUtilityClass</code></a>: The property <code class="language-plaintext highlighter-rouge">ignoredAnnotations</code> has been removed.</li>
</ul>
<p><strong>Java Documentation</strong></p>
<ul>
<li><a href="pmd_rules_java_documentation.html#commentcontent"><code class="language-plaintext highlighter-rouge">CommentContent</code></a>: The properties <code class="language-plaintext highlighter-rouge">caseSensitive</code> and <code class="language-plaintext highlighter-rouge">disallowedTerms</code> are removed. The
new property <code class="language-plaintext highlighter-rouge">forbiddenRegex</code> can be used now to define the disallowed terms with a single regular
expression.</li>
<li><a href="pmd_rules_java_documentation.html#commentrequired"><code class="language-plaintext highlighter-rouge">CommentRequired</code></a>:
<ul>
<li>Overridden methods are now detected even without the <code class="language-plaintext highlighter-rouge">@Override</code>
annotation. This is relevant for the property <code class="language-plaintext highlighter-rouge">methodWithOverrideCommentRequirement</code>.
See also <a href="https://github.com/pmd/pmd/pull/3757">pull request #3757</a>.</li>
<li>Elements in annotation types are now detected as well. This might lead to an increased number of violations
for missing public method comments.</li>
</ul>
</li>
<li><a href="pmd_rules_java_documentation.html#commentsize"><code class="language-plaintext highlighter-rouge">CommentSize</code></a>: When determining the line-length of a comment, the leading comment
prefix markers (e.g. <code class="language-plaintext highlighter-rouge">*</code> or <code class="language-plaintext highlighter-rouge">//</code>) are ignored and don’t add up to the line-length.
See also <a href="https://github.com/pmd/pmd/pull/4369">pull request #4369</a>.</li>
</ul>
<p><strong>Java Error Prone</strong></p>
<ul>
<li><a href="pmd_rules_java_errorprone.html#avoidduplicateliterals"><code class="language-plaintext highlighter-rouge">AvoidDuplicateLiterals</code></a>: The property <code class="language-plaintext highlighter-rouge">exceptionfile</code> has been removed. The property was
deprecated since PMD 6.10.0. Use the property <code class="language-plaintext highlighter-rouge">exceptionList</code> instead.</li>
<li><a href="pmd_rules_java_errorprone.html#dontimportsun"><code class="language-plaintext highlighter-rouge">DontImportSun</code></a>: <code class="language-plaintext highlighter-rouge">sun.misc.Signal</code> is not special-cased anymore.</li>
<li><a href="pmd_rules_java_errorprone.html#emptycatchblock"><code class="language-plaintext highlighter-rouge">EmptyCatchBlock</code></a>: <code class="language-plaintext highlighter-rouge">CloneNotSupportedException</code> and <code class="language-plaintext highlighter-rouge">InterruptedException</code> are not
special-cased anymore. Rename the exception parameter to <code class="language-plaintext highlighter-rouge">ignored</code> to ignore them.</li>
<li><a href="pmd_rules_java_errorprone.html#implicitswitchfallthrough"><code class="language-plaintext highlighter-rouge">ImplicitSwitchFallThrough</code></a>: Violations are now reported on the case statements
rather than on the switch statements. This is more accurate but might result in more violations now.</li>
</ul>
<h4 id="removed-rules">Removed Rules</h4>
<p>Many rules, that were previously deprecated have been finally removed.
See <a href="pmd_release_notes_pmd7.html">Detailed Release Notes for PMD 7</a> for the complete list.</p>
<h3 id="-api">🚨 API</h3>
<p>The API of PMD has been growing over the years and needed some cleanup. The goal is, to
have a clear separation between a well-defined API and the implementation, which is internal.
This should help us in future development.</p>
<p>Also, there are some improvement and changes in different areas. For the detailed description
