What is the info on the fork? Why is it so damn hard to find any official information? Is it out there?

Some things I wonder.

1 What do I need to do to participate in the fork? Just hold my Zclassic in my desktop wallet?

2 Do I need to update my wallet to some certain version? (I have the old 0.0.5 version of the wallet). If I need to update? Do I need to make a backup?

3 When is the date of the fork?
