updated readme and added birthday flag to examples

is this still true now we have re-implemented the manual shielding button?

i think this was a security risk maybe? where an attacker could dust a non-orchard pool and watch the note management automatically shield when the user sent funds?

"releases are currently only provisional" what does this mean? is this correct?

It's still true for sapling, I think! It's no longer true for transparent.

You can still attempt to dust sapling and learn which transactions someone is sending if they don't shield first. It's no where near as leaky as it was when you could do the same with the transparent pool, but it's still a viable attack
