    30-September-2023 - 7.0.0-rc4

We're excited to bring you the next major version of PMD!

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 Detailed Release Notes for PMD 7.0.0 
<https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_release_notes_pmd7.html>.

*ℹ️ Release Candidates*

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.

We have still some tasks planned for the next release candidates. You 
can see the progress in PMD 7 Tracking Issue #3898 
<https://github.com/pmd/pmd/issues/3898>.

If you find any problem or difficulty while updating from PMD 6, please 
provide feedback via our issue tracker 
<https://github.com/pmd/pmd/issues/new/choose>. That way we can improve 
the experience for all.

      Changes since 7.0.0-rc3

This section lists the most important changes from the last release 
candidate.
The remaining section describes the complete release notes for 7.0.0.

        New and Noteworthy

          Migration Guide for PMD 7

A detailed documentation of required changes are available in the
Migration Guide for PMD 7 
<https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_userdocs_migrating_to_pmd7.html>.

          Apex Jorje Updated

With the new version of Apex Jorje, the new language constructs like 
User Mode Database Operations
can be parsed now. PMD should now be able to parse Apex code up to 
version 59.0 (Winter '23).

          Java 21 Support

This release of PMD brings support for Java 21. There are the following 
new standard language features,
that are supported now:

  * JEP 440: Record Patterns <https://openjdk.org/jeps/440>
  * JEP 441: Pattern Matching for switch <https://openjdk.org/jeps/441>

PMD also supports the following preview language features:

  * JEP 430: String Templates (Preview) <https://openjdk.org/jeps/430>
  * JEP 443: Unnamed Patterns and Variables (Preview)
    <https://openjdk.org/jeps/443>
  * JEP 445: Unnamed Classes and Instance Main Methods (Preview)
    <https://openjdk.org/jeps/445>

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 |21-preview|:

|exportPMD_JAVA_OPTS=--enable-preview 
pmdcheck--use-versionjava-21-preview... |

Note: Support for Java 19 preview language features have been removed. 
The version "19-preview" is no longer available.

        API Changes

          pmd-java

  * Support for Java 19 preview language features have been removed. The
    version "19-preview" is no longer available.

          Rule properties

  * The old deprecated classes like |IntProperty| and |StringProperty|
    have been removed. Please use
    |PropertyFactory|
    <https://docs.pmd-code.org/apidocs/pmd-core/7.0.0-rc4/net/sourceforge/pmd/properties/PropertyFactory.html#>
    to create properties.
  * All properties which accept multiple values now use a comma (|,|) as
    a delimiter. The previous default was a
    pipe character (|||). The delimiter is not configurable anymore. If
    needed, the comma can be escaped
    with a backslash.
  * The |min| and |max| attributes in property definitions in the XML
    are now optional and can appear separately
    or be omitted.

          New Programmatic API for CPD

See Detailed Release Notes for PMD 7 
<https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_release_notes_pmd7.html#new-programmatic-api-for-cpd>

        New: Java 21 Support

This release of PMD brings support for Java 21. There are the following 
new standard language features,
that are supported now:

  * JEP 440: Record Patterns <https://openjdk.org/jeps/440>
  * JEP 441: Pattern Matching for switch <https://openjdk.org/jeps/441>

PMD also supports the following preview language features:

  * JEP 430: String Templates (Preview) <https://openjdk.org/jeps/430>
  * JEP 443: Unnamed Patterns and Variables (Preview)
    <https://openjdk.org/jeps/443>
  * JEP 445: Unnamed Classes and Instance Main Methods (Preview)
    <https://openjdk.org/jeps/445>

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 |21-preview|:

|exportPMD_JAVA_OPTS=--enable-preview 
pmdcheck--use-versionjava-21-preview... |

Note: Support for Java 19 preview language features have been removed. 
The version "19-preview" is no longer available.

        Changed: JavaScript support

  * latest version supports ES6 and also some new constructs (see Rhino
    <https://github.com/mozilla/rhino>])
  * comments are retained

        Changed: Language versions

  * more predefined language versions for each supported language
  * can be used to limit rule execution for specific versions only with
    |minimumLanguageVersion| and
    |maximumLanguageVersion| attributes.

        Changed: CPP can now ignore identifiers in sequences (CPD)

  * new command line option for CPD: |--ignore-sequences|.
  * This option is used for CPP only: with the already existing option
    |--ignore-literal-sequences|, only
    literals were ignored. The new option additional ignores identifiers
    as well in sequences.
  * See PR #4470 <https://github.com/pmd/pmd/pull/4470> for details.

        Changed: Apex Jorje Updated

With the new version of Apex Jorje, the new language constructs like 
User Mode Database Operations
can be parsed now. PMD should now be able to parse Apex code up to 
version 59.0 (Winter '23).

        Changed: Rule properties

  * The old deprecated classes like |IntProperty| and |StringProperty|
    have been removed. Please use
    |PropertyFactory|
    <https://docs.pmd-code.org/apidocs/pmd-core/7.0.0-rc4/net/sourceforge/pmd/properties/PropertyFactory.html#>
    to create properties.
  * All properties which accept multiple values now use a comma (|,|) as
    a delimiter. The previous default was a
    pipe character (|||). The delimiter is not configurable anymore. If
    needed, the comma can be escaped
    with a backslash.
  * The |min| and |max| attributes in property definitions in the XML
    are now optional and can appear separately
    or be omitted.

      🌟 New and changed rules

        Changed Rules

*General changes*

  *

    All statistical rules (like ExcessiveClassLength,
    ExcessiveParameterList) have been simplified and unified.
    The properties |topscore| and |sigma| have been removed. The
    property |minimum| 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):

      o Apex: |ExcessiveClassLength|
        <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_apex_design.html#excessiveclasslength>,
        |ExcessiveParameterList|
        <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_apex_design.html#excessiveparameterlist>,

        |NcssMethodCount|
        <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_apex_design.html#ncssmethodcount>,
        |NcssTypeCount|
        <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_apex_design.html#ncsstypecount>
      o Java: |ExcessiveImports|
        <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_design.html#excessiveimports>,
        |ExcessiveParameterList|
        <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_design.html#excessiveparameterlist>,
        |ExcessivePublicCount|
        <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_design.html#excessivepubliccount>,
        |SwitchDensity|
        <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_design.html#switchdensity>
      o PLSQL: |ExcessiveMethodLength|
        <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_plsql_design.html#excessivemethodlength>,
        |ExcessiveObjectLength|
        <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_plsql_design.html#excessiveobjectlength>,
        |ExcessivePackageBodyLength|
        <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_plsql_design.html#excessivepackagebodylength>,
        |ExcessivePackageSpecificationLength|
        <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_plsql_design.html#excessivepackagespecificationlength>,
        |ExcessiveParameterList|
        <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_plsql_design.html#excessiveparameterlist>,
        |ExcessiveTypeLength|
        <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_plsql_design.html#excessivetypelength>,
        |NcssMethodCount|
        <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_plsql_design.html#ncssmethodcount>,
        |NcssObjectCount|
        <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_plsql_design.html#ncssobjectcount>,
        |NPathComplexity|
        <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_plsql_design.html#npathcomplexity>
      o VM: |ExcessiveTemplateLength|
        <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_vm_design.html#excessivetemplatelength>
  *

    The general property |violationSuppressXPath| which is available for
    all rules to
    suppress warnings
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_userdocs_suppressing_warnings.html>
    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
    |violationSuppressXPath| properties.

*Apex General changes*

  * The properties |cc_categories|, |cc_remediation_points_multiplier|,
    |cc_block_highlighting| have been removed
    from all rules. These properties have been deprecated since PMD 6.13.0.
    See issue #1648 <https://github.com/pmd/pmd/issues/1648> for more
    details.

*Java General changes*

  * 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. |CognitiveComplexity|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_design.html#cognitivecomplexity>.

The report location is controlled by the overrides of the method 
|getReportLocation| 
<https://docs.pmd-code.org/apidocs/pmd-core/7.0.0-rc4/net/sourceforge/pmd/lang/ast/Node.html#getReportLocation()>
in different node types.

See issue #4439 <https://github.com/pmd/pmd/issues/4439> and issue #730 
<https://github.com/pmd/pmd/issues/730>
for more details.

*Java Best Practices*

  * |ArrayIsStoredDirectly|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_bestpractices.html#arrayisstoreddirectly>:
    Violations are now reported on the assignment and not
    anymore on the formal parameter. The reported line numbers will
    probably move.
  * |AvoidReassigningLoopVariables|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_bestpractices.html#avoidreassigningloopvariables>:
    This rule might not report anymore all
    reassignments of the control variable in for-loops when the property
    |forReassign| is set to |skip|.
    See issue #4500 <https://github.com/pmd/pmd/issues/4500> for more
    details.
  * |LooseCoupling|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_bestpractices.html#loosecoupling>:
    The rule has a new property to allow some types to be coupled
    to (|allowedTypes|).
  * |UnusedLocalVariable|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_bestpractices.html#unusedlocalvariable>:
    This rule has some important false-negatives fixed
    and finds many more cases now. For details see issues #2130
    <https://github.com/pmd/pmd/issues/2130>,
    #4516 <https://github.com/pmd/pmd/issues/4516>, and #4517
    <https://github.com/pmd/pmd/issues/4517>.

*Java Codestyle*

  * |MethodNamingConventions|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_codestyle.html#methodnamingconventions>:
    The property |checkNativeMethods| has been removed. The
    property was deprecated since PMD 6.3.0. Use the property
    |nativePattern| to control whether native methods
    should be considered or not.
  * |ShortVariable|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_codestyle.html#shortvariable>:
    This rule now also reports short enum constant names.
  * |UseDiamondOperator|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_codestyle.html#usediamondoperator>:
    The property |java7Compatibility| has been removed. The rule now
    handles Java 7 properly without a property.
  * |UnnecessaryFullyQualifiedName|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_codestyle.html#unnecessaryfullyqualifiedname>:
    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.
  * |UselessParentheses|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_codestyle.html#uselessparentheses>:
    The rule has two new properties which control how strict
    the rule should be applied. With |ignoreClarifying| (default: true)
    parentheses that are strictly speaking
    not necessary are allowed, if they separate expressions of different
    precedence.
    The other property |ignoreBalancing| (default: true) is similar, in
    that it allows parentheses that help
    reading and understanding the expressions.

*Java Design*

  * |CyclomaticComplexity|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_design.html#cyclomaticcomplexity>:
    The property |reportLevel| 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
    |classReportLevel| and |methodReportLevel| instead.
  * |ImmutableField|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_design.html#immutablefield>:
    The property |ignoredAnnotations| has been removed. The property was
    deprecated since PMD 6.52.0.
  * |LawOfDemeter|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_design.html#lawofdemeter>:
    The rule has a new property |trustRadius|. This defines the maximum
    degree
    of trusted data. The default of 1 is the most restrictive.
  * |NPathComplexity|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_design.html#npathcomplexity>:
    The property |minimum| has been removed. It was deprecated since PMD
    6.0.0.
    Use the property |reportLevel| instead.
  * |SingularField|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_design.html#singularfield>:
    The properties |checkInnerClasses| and |disallowNotAssignment| have
    been removed.
    The rule is now more precise and will check these cases properly.
  * |UseUtilityClass|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_design.html#useutilityclass>:
    The property |ignoredAnnotations| has been removed.

*Java Documentation*

  * |CommentContent|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_documentation.html#commentcontent>:
    The properties |caseSensitive| and |disallowedTerms| are removed. The
    new property |forbiddenRegex| can be used now to define the
    disallowed terms with a single regular
    expression.
  * |CommentRequired|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_documentation.html#commentrequired>:

      o Overridden methods are now detected even without the |@Override|
        annotation. This is relevant for the property
        |methodWithOverrideCommentRequirement|.
        See also pull request #3757 <https://github.com/pmd/pmd/pull/3757>.
      o Elements in annotation types are now detected as well. This
        might lead to an increased number of violations
        for missing public method comments.
  * |CommentSize|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_documentation.html#commentsize>:
    When determining the line-length of a comment, the leading comment
    prefix markers (e.g. |*| or |//|) are ignored and don't add up to
    the line-length.
    See also pull request #4369 <https://github.com/pmd/pmd/pull/4369>.

*Java Error Prone*

  * |AvoidDuplicateLiterals|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_errorprone.html#avoidduplicateliterals>:
    The property |exceptionfile| has been removed. The property was
    deprecated since PMD 6.10.0. Use the property |exceptionList| instead.
  * |DontImportSun|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_errorprone.html#dontimportsun>:
    |sun.misc.Signal| is not special-cased anymore.
  * |EmptyCatchBlock|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_errorprone.html#emptycatchblock>:
    |CloneNotSupportedException| and |InterruptedException| are not
    special-cased anymore. Rename the exception parameter to |ignored|
    to ignore them.
  * |ImplicitSwitchFallThrough|
    <https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_rules_java_errorprone.html#implicitswitchfallthrough>:
    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.

        Removed Rules

Many rules, that were previously deprecated have been finally removed.
See Detailed Release Notes for PMD 7 
<https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_release_notes_pmd7.html> 
for the complete list.

      🚨 API

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.

Also, there are some improvement and changes in different areas. For the 
detailed description
of the changes listed here, see Detailed Release Notes for PMD 7 
<https://docs.pmd-code.org/pmd-doc-7.0.0-rc4/pmd_release_notes_pmd7.html>.

  * Miscellaneous smaller changes and cleanups
  * XPath 3.1 support for XPath-based rules
  * Node stream API for AST traversal
  * Metrics framework
  * Testing framework
  * Language Lifecycle and Language Properties
  * Rule Properties
  * New Programmatic API for CPD
