Changelog for Groovy 6.0.0-beta-1

Bug

[GROOVY-11792] - for-in loop variable captured by closure/AIC sees final value, not per-iteration value
[GROOVY-12125] - deleteDir() should treat symbolic links as leaves
[GROOVY-12134] - @Delegate regression: fails to skip a final method inherited from a precompiled superclass
[GROOVY-12139] - Primitive array Varargs Java incompatibility (fix needed also for classic bytecode)
[GROOVY-12144] - AstNodeToScriptAdapter decompiler drops or corrupts several constructs when rendering AST back to source
[GROOVY-12145] - JUnit 5 migration silently disabled ~195 test methods: base class removed but @Test not added

[GROOVY-12148] - fix out-of-bounds read on dangling escape in decodeJsonString
[GROOVY-12149] - Nondeterministic reflection order flows into generated bytecode, breaking reproducible builds
[GROOVY-12154] - `@CompileStatic` lambda with a primitive-typed parameter targeting a generic functional interface fails at runtime with `LambdaConversionException`

[GROOVY-12186] - reject lone low surrogate in StreamingMarkupWriter.write
[GROOVY-12190] - @TypeChecked switch on enum: unqualified case constants pass type checking but throw MissingPropertyException at runtime
[GROOVY-12203] - False positive "name clash" for a valid override when a `? super` wildcard uses a type that declares the same type variable name
[GROOVY-12213] - avoid decoding the request URI in HttpBuilder.appendQuery
[GROOVY-12219] - Lazy iterators that prefetch remove the wrong element in DefaultGroovyMethods
