Typo and slightly confusing note

[paulwib]

Note: work is currently ongoing for Flight v2 and beyond, which will make some backward incompatibile changes. To see the latest v1.x code and documentation, check out the barnch.

So is the v2 dev happening on master? I was confused as there is a v.2.0.0-dev branch too.

Hey @paulwib — thanks for reporting these, I'll fix them right away.

Yes, v2 is happening on master — I'll delete the v2 branch too.
