Question for Dynon:
Is there any plans on beefing up the shear screws a little? :

That is good news.No firm plans at the moment. You want it strong enough to not break during normal use, but you definitely want it to yield if something goes wrong mechanically. All of that said, we're seeing more screws shearing than we'd expect, and we're looking into that.
Outstanding.While most aircraft never break shear screws (there are literally thousands of Dynon autopilots installed in the world), there are some that are able to break them, sometimes more than once as you've experienced. We're actually doing a pretty deep engineering investigation of the phenomenon right now. While I don't have results to report just yet, I do want to communicate that we're taking a hard look at what's going on in these cases and hope to have more to report soon.
Attention Dynon Tech Support:In my humble opinion, those shear screws need to be beefed up a little.
Thank you.Yes, this is still a very active project here. Nothing specific to report out at the moment.
An update here: Our updated shear screw design is shipping now, but we haven't made any big announcements yet. If you've had past issues with shear screws breaking (particularly more than once) do fill out a request at http://www.dynonavionics.com/shearscrew. If you haven't had issues with broken shear screws and yours isn't broken now, there is need to replace yours.
