Today we published a WPF Controls maintenance release v2016.1 build 635. The updates are described in detail in this post. It is highly recommended that you download this maintenance release since it fixes several issues that popped up with the Docking/MDI product and makes several other minor enhancements as well.
We are now at a stage where we are about to start prepping our codebases for the upcoming 2017.1 version. Over the past few months, we've been working on an array of new and revised controls for that version, and will begin merging all that in over the coming weeks. Look for a beta testing request announcement in very early 2017.
Everyone, please have a wonderful holiday season and happy new year!
