    25-March-2023 - 7.0.0-rc1

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://pmd.github.io/pmd-7.0.0-rc1/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.

  * Java grammar substantially refactored - more correct regarding the
    Java Language Specification (JLS)
  * Built-in rules have been upgraded for the changed AST
  * Rewritten type resolution framework and symbol table correctly
    implements the JLS

        Revamped Command Line Interface

  * unified and consistent Command Line Interface for both Linux/Unix
    and Windows across our different utilities
  * single script |pmd| (|pmd.bat| for Windows) to launch the different
    utilities:
  * |pmd check| to run PMD rules and analyze a project
  * |pmd cpd| to run CPD (copy paste detector)
  * |pmd designer| to run the PMD Rule Designer
  * progress bar support for |pmd check|
  * shell completion

        Full Antlr support

  * Antlr <https://www.antlr.org/> based grammars can now be used to
    build full-fledged PMD rules.
  * Previously, Antlr grammar could only be used for CPD
  * New supported languages: Swift and Kotlin

    |minimumLanguageVersion| and
    |maximumLanguageVersion| attributes.


      🌟 New and changed rules


        New Rules

*Apex* * |UnusedMethod| 
<https://pmd.github.io/pmd-7.0.0-rc1/pmd_rules_apex_design.html#unusedmethod> 
finds unused methods in your code.

*Java* * |UnnecessaryBoxing| 
<https://pmd.github.io/pmd-7.0.0-rc1/pmd_rules_java_codestyle.html#unnecessaryboxing> 
reports boxing and unboxing conversions that may be made implicit.

*Kotlin* * |FunctionNameTooShort| 
<https://pmd.github.io/pmd-7.0.0-rc1/pmd_rules_kotlin_bestpractices.html#functionnametooshort> 
* |OverrideBothEqualsAndHashcode| 
<https://pmd.github.io/pmd-7.0.0-rc1/pmd_rules_kotlin_errorprone.html#overridebothequalsandhashcode>

*Swift* * |ProhibitedInterfaceBuilder| 
<https://pmd.github.io/pmd-7.0.0-rc1/pmd_rules_swift_bestpractices.html#prohibitedinterfacebuilder> 
* |UnavailableFunction| 
<https://pmd.github.io/pmd-7.0.0-rc1/pmd_rules_swift_bestpractices.html#unavailablefunction> 
* |ForceCast| 
<https://pmd.github.io/pmd-7.0.0-rc1/pmd_rules_swift_errorprone.html#forcecast> 
* |ForceTry| 
<https://pmd.github.io/pmd-7.0.0-rc1/pmd_rules_swift_errorprone.html#forcetry>


        Changed Rules

*Java*

  * |UnnecessaryFullyQualifiedName|
    <https://pmd.github.io/pmd-7.0.0-rc1/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://pmd.github.io/pmd-7.0.0-rc1/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.
  * |LooseCoupling|
    <https://pmd.github.io/pmd-7.0.0-rc1/pmd_rules_java_bestpractices.html#loosecoupling>:
    the rule has a new property to allow some types to be coupled
    to (|allowedTypes|).
  * |EmptyCatchBlock|
    <https://pmd.github.io/pmd-7.0.0-rc1/pmd_rules_java_errorprone.html#emptycatchblock>:
    |CloneNotSupportedException| and |InterruptedException| are not
    special-cased anymore. Rename the exception parameter to |ignored|
    to ignore them.
  * |DontImportSun|
    <https://pmd.github.io/pmd-7.0.0-rc1/pmd_rules_java_errorprone.html#dontimportsun>:
    |sun.misc.Signal| is not special-cased anymore.
  * |UseDiamondOperator|
    <https://pmd.github.io/pmd-7.0.0-rc1/pmd_rules_java_codestyle.html#usediamondoperator>:
    the property |java7Compatibility| is removed. The rule now
    handles Java 7 properly without a property.
  * |SingularField|
    <https://pmd.github.io/pmd-7.0.0-rc1/pmd_rules_java_design.html#singularfield>:
    Properties |checkInnerClasses| and |disallowNotAssignment| are removed.
    The rule is now more precise and will check these cases properly.
  * |UseUtilityClass|
    <https://pmd.github.io/pmd-7.0.0-rc1/pmd_rules_java_design.html#useutilityclass>:
    The property |ignoredAnnotations| has been removed.
  * |LawOfDemeter|
    <https://pmd.github.io/pmd-7.0.0-rc1/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.
  * |CommentContent|
    <https://pmd.github.io/pmd-7.0.0-rc1/pmd_rules_java_documentation.html#commentcontent>:
    The properties |caseSensitive| and |disallowedTerms| are removed. The
    new property |fobiddenRegex| can be used now to define the
    disallowed terms with a single regular
    expression.


        Removed Rules

Many rules, that were previously deprecated have been finally removed.
See Detailed Release Notes for PMD 7 
<https://sourceforge.net/p/pmd/news/2023/03/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://sourceforge.net/p/pmd/news/2023/03/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
