New and noteworthy

New rules

• The new Java rule {% rule "java/bestpractices/UseStandardCharsets" %} finds usages of Charset.forName, where StandardCharsets can be used instead.

  This rule is also part of the Quickstart Ruleset (rulesets/java/quickstart.xml) for Java.

• The new Java rule {% rule "java/codestyle/UnnecessaryImport" %} replaces the rules {% rule "java/bestpractices/UnusedImports" %}, {% rule "java/codestyle/DuplicateImports" %}, {% rule "java/errorprone/ImportFromSamePackage" %}, and {% rule "java/codestyle/DontImportJavaLang" %}.

  This rule is also part of the Quickstart Ruleset (rulesets/java/quickstart.xml) for Java.
