MapStruct 1.4.0.Beta2 is out

Today we release a new beta version of MapStruct 1.4.0. We are very happy to have received good feedback from our users. However, it is like always when writing software bugs are made and are there to be solved. So what did we tackle in 1.4.0.Beta2

• Improve performance for 2 step mapping methods
• Having 2 step mapping methods, based on a generic -in between- type. For example: source (String) -> Embeded mapStringToEmbeded(String s) -> List toSingleElementList( T e ) -> target (List)
• Improved error messages for qualifiers

11 issues were fixed for this release.

Thanks to our MapStruct community for being vigilant. The MapStruct authors: Filip Hrisafov, Christian Bandowski, Andrei Arlou and Sjaak Derksen.

Thank you everyone for all your hard work!
