Yes, version 4.9.16 has been released. It includes a fix for the memory usage increase when sharing a lot of small files (tens of thousands), and some further workarounds for the SP2 connection problems.

If you are running 4.9.13 and its been doing just fine when it comes to staying connected and has been stable - keep running that - we'd like to see how far it can go

If you happened to download 4.9.14 or 4.9.15 you should upgrade to 4.9.16 and give it a spin!
