Bug Fixes

TextFileBasedViolationStore now correctly handles empty violation store files (see #456; thanks a lot to @hankem)
Fix URL scheme part issue on Windows when reading classpath URLs from manifest files (see #414; thanks a lot to @eriklumme)

Enhancements

Reduce excessive logging if archunit.properties are overwritten by system properties (see #375; thanks a lot to @ldebruijn)
New method JavaClass.tryGetConstructor() (see #386; thanks a lot to @rweisleder)
JavaClass now provides generic type information, i.e. there is now JavaClass.getTypeParameters() (see #398). Furthermore JavaClass now reports type parameter bounds as Dependencies (see #484)
JavaClass now offers JavaClass.getInstanceofChecks(), which are also reported as Dependencies (see #371; thanks a lot to @t-h-e)
Support for Java 15 and 16-ea (see #409)
Resolve imported annotations transitively with the configured ClassResolver (i.e. by default from the classpath). This will make detection of meta-annotations work out of the box now in many cases, without the need to explicitly import these meta-annotation types as well (see #342, #450; thanks a lot to @KorSin)
New method JavaClass.getBaseComponentType() (see #441; thanks a lot to @hankem)
Component types (i.e. String for an array String[]) are now detected as dependencies of JavaClass (see #257; thanks a lot to @wengertj)
New method ..archunit..Optional.getOrThrow(Supplier) (see #391; thanks a lot to @idosal)
New method JavaClass.getTransitiveDependenciesFromSelf() (see #401; thanks a lot to @hankem)

New syntax members().that().haveName{StartingWith/Containing/EndingWith}(..) and members().should().haveName{StartingWith/Containing/EndingWith}(..) (see #239; thanks a lot to @kamer)
Improve CompositeArchRule.of(..) to accept an Iterable of ArchRule (see #384; thanks a lot to @sullis)
Clarify difference between access and depend in rule Javadocs (see #313; thanks a lot to @idosal)
New syntax classes().that().are{Not}Annotations() (see #468)
New syntax classes().that().doNotBelongToAnyOf(..) (see #422; thanks a lot to @perlun)
