mapstruct/mapstruct 1.5.0.Beta1 on GitHub

Support for Mapping from Map<String, ???> to Bean (#1075)
Conditional mapping (#2051, #2084) - Support for custom source presence checker expressions for mappings and custom method mappings
Support mapping Iterable<?> object to an object instead of collection (#607)
Support for case changing enum transformation strategy #2445
Built-In conversion between String <-> StringBuilder (#597)
Built-In conversion between a UUID to a String (#2391)
Support throwing an exception as an Enum Mapping option (#2339)

Add constants for componentModel in MappingConstants.ComponentModel (#2255)
Reuse singleton INSTANCE (if it exists) in mapper references when using the default component model (#2277)
[Breaking Change] Retain iteration order for Sorted(Map|Set) values (#2303) - In order to keep the previous behaviour and use Hash(Map|Set) use an @ObjectFactory
unmappedTargetPolicy for @BeanMapping (#2132)
Optimization: Make java.time.format.DateTimeFormatter instances final members (#2329)
[Breaking Change] Report ignored source properties which are missing (#2481) - Previously unknown properties in BeanMapping#ignoreUnmappedSourceProperties were ignored, now there will be a compile error as it is most likely a mistake. To fix the error the unknown properties should be removed from BeanMapping#ignoreUnmappedSourceProperties

Multiple source properties with defaultExpression lead to unnecessary null checks and unexpected code (#2023)
MappingTarget member cannot be set to null (#2274)
Import statement not being generated for custom type extending from an Iterable (#2352)
Compilation failure when mapper interface is a private nested interface (#2347)
When using @ValueMapping string-to-enum mapping results in no cases in switch (#2350)
Passing of mapping method argument to a property and using @InheritInverseConfiguration (#2356)
Incorrect mapper generated when upgrading from 1.2.0.Final to 1.4.2.Final (#2393)
Several source parameters do not support "." (#2402)
Source presence checks on collections with non direct mappings is ignored (#2423)
Mapstruct mappers diamond inheritance, method is already defined (#2437)
ObjectFactory with generic source not in generated code in after generics refactorings (#2463)\
Variable is already defined in method (#2478)
With wrong config like Enum[] to String, the mapping processor throws NPE (#2439)
JaxbElem not used when jaxb-api not on annotation processor path on Java 11 (#2491)
DeepClone generates cloning method for Enums #2505
