What is newest update for the Motorola Maxx?

Question

I am currently running Android 4.4.4 and Software 24.13.2.obake-maxx_verizon.Verizon.en.US

I got a notification today (11/4) that there is system update available.  An internet search comes up with Software 21.11.21.obake-maxx_verizon.Verizon.en.US as the latest available and I am obviously one up from that.  What does this newest update entail?  Seems like every time I upgrade, something stops working.

Thanks for any input.

Android Security Updates. (Stagefright bug fix is likely in it.)
