Hi Guys,
I am back on the Android bandwagon after a good 5-6 years of break and starting the journey with an unlocked Xperia Z3.
I have not looked into flashing custom ROMs as I have just bought the device and don't really have time these days to go mental with modding and changing things around. 
A quick Google search revealed that the latest official Android version for my specific model - D6603 is Android 6.0.1. However, my phone is on 5.1.1 currently and if I try to look for update, it says I have already got the latest version. I am in the UK and I thought that the global roll out was at the end of April. Any idea why the update is not available for me?!
