Hi @kent1ukr
Java updates have been implemented among successive versions since 16.10.3, but it’s true that this one it still the latest official package for WP85 (please refer to http://legato.io/legato-docs/latest/aboutReleaseInfo.html for more information on how hardware package releases are scheduled WRT. the master monthly releases)
That said, you still can build the Framework by your own, at the version you want, and get it into DS so that you can build apps on top of it (Instructions here: Adding newest version Legato Framework into Developer Studio)
