Release 2.0.0-M1

Release 2.0.0-M1 is the first milestone release for our next major release 2.0.0 and contains several breaking changes. That's why we will support both 1.x and 2.x for some time.
The following table provides an overview about the supported specs and frameworks:

Version	Branch	Java Enterprise support	Spring versions	JAX-RS/ Jersey version	Struts support	Spark support
1.x	1.x	Java EE (javax.*)	5.x (Boot 2.x)	2.x	✅	✅
2.x	main	Jakarta EE (jakarta.*)	6.x (Boot 3.x)	3.x	❌	❌

Please note that multipart upload functionality is currently not supported as we are waiting for a release of Apache Commons Fileupload 2 (see https://issues.apache.org/jira/browse/FILEUPLOAD-309).
