10,000 Pull Requests

[Maximilian Michels]

Just wanted to point out, we have crossed the 10,000 PRs mark :)
...and the winner is: https://github.com/apache/beam/pull/10000

Seriously, I think Beam's culture to promote PRs over direct access to 
the repository is remarkable. To another 10,000 PRs!

Cheers,
Max
