A small firmware update with build number 28.0.A.8.272 is now rolling for the Xperia Z3+ and Z3+ Dual. The update moves the handset from build number 28.0.A.8.266 and keeps the handset on Android 5.0.2 Lollipop. This very well could be the last update before we see Android 6.0 Marshmallow hitting the handset directly, although Sony has not confirmed the timeline for this yet. We will keep you posted on further developments. In the meantime, you can download the FTF firmware files for both variants below.
