Is there anyone updated the wallet? I am not sure if I should backup the whole wallet first before update

I did update my wallet with no issues
You should always take a backup before applying an update on the wallet
Always backup.
Prior to an update, after an update, and
before and after blackbyte payments.
Like I said before, no one has complained about having too many backups. People always complain when they didn't have a backup they needed.
Got my 10% 18 hours ago. Thanks for the airdrop!
were blackbytes distributed already?
I am yet to receive GBB as well. These usually take a little while longer to distribute.
Like Tony said less than a day ago....
Distribution of bytes is finished.
Total distributed: 57,444.473272169 GB. It's about $19m at the current rate.
New available supply: 583,896.4940036 GB. Coinmarketcap is already updated.
I'll update when blackbytes are distributed, it is going to take about 3 days.
3 - 1 = approximately 2 days. (Maths)
