On behalf of the team, it is my very great pleasure to announce that the Holon Platform version 5.1.0 is now generally available from Maven Central.
Along with all the latest bug fixes, there is also a lot of useful features that are made available with the 5.1 minor release. Just to give some examples:
PropertySetidentifier properties support.
PathPropertyAPIs to easily deal with most common property data types in a more consistent way.
java.time.*Date and Time API in all the suitable platform modules.
JsonAPI to easily deal with JSON serialization and deserialization in a library-independent way.
Furthermore, a great deal of work has been done on the Holon Platform documentation, to make it even more complete, detailed and useful, providing a great number of code samples and cross-references to the core API sections.
See What's new in version 5.1 for the full list of changes and the detailed release notes.
The public Java API is fully compatible with the previous versions, for a seamless migration from version 5.0.x.
So don't wait any longer and start from here with the new platform version.
