v3.0.0rc1

[3.0.0-rc1] - 2023-04-11

This new major version is containing lots of internal re-architecture processes in the source code, and upgrades the
internal quality of PhpMetrics to a new level. Nevertheless, it contains also some BC Breaks and some metrics are
remove. Please take a look at the detailed changelog below if you experiment any trouble.

BC Break

• PhpMetrics 3.0 is requiring PHP 8.1 minimum. To parse projects that are not yet in PHP 8.1, please use a docker
  installation based on a PHP 8.1 Docker Image
• Git and JUnit plugins are no longer allowed in the configuration file

Removed

• Installation and usage from Debian package. Please use the phar, composer, or docker instead
• Metric removed: Git related metrics
• Metric removed: PHPUnit related metrics
• Metric removed: PageRank metric
• Metric removed: On System Complexity, totalStructuralComplexity, totalDataComplexity and totalSystemComplexity.
• Metric removed: On class-method enumeration, nbGetters and nbSetters are removed as no particular metric needs them.

New features

• Internal: Install a real dedicated QA system to secure PhpMetrics as mch as possible
• Internal: QA System is composed of PHP_CodeSniffer, PHPUnit, PHP Infection, PHPStan, Psalm and Qodana
• Internal: Make possible to create releases with suffixed names
• Minor UX/UI improvements on the HTML report.

Fixed

• Internal: QA completely upgraded. PHPCS, PHPStan, Psalm and Qodana are no longer having errors except on baseline.
  Coverage is very close to 100%. All unit tests are passing. Mutation Score >94%. Some improvements are yet to come
• Metric calculations: Fix LCoM calculation that was not able to understand promoted properties in constructor.
• Metric calculations: Ignore PHP Attributes in the detection of getters and setters. This fixes LCoM calculation.
• Metric calculations: Improve calculation on Afferent Coupling and Efferent Coupling (+ related metrics) thanks to
  enlarged context of external classes usages detection.
• Metric calculations: Take NullSafeMethodCall ($x?->y()) into account for WeightMethodCount and Cyclomatic Complexity calculation.
• Metric calculations: Take NullSafePropertyFetch ($x?->y) into account for WeightMethodCount and Cyclomatic Complexity calculation.
• Metric calculations: Take newly introduced match structure into account for WeightMethodCount and Cyclomatic Complexity calculation.
• Metric calculations: Improve KanDefect metrics as match are now took into account as number of selects, along with switches.
• Metric calculations: On System Complexity, relative complexities are now calculated including NullSafeMethodCall ($x?->y()).
