Thanks you Felix. There are five contributors. Of those, the four contributors from IBM already have Apache CLAs on file: Olivier Tardieu, Nick Mitchell, Kerry Chang and Rodric Rabbah.
There is one commit - a small typo fix to documentation - https://github.com/ibm-functions/composer/pull/23/files from a contributor without an Apache CLA (Travis Cox). -r > On Sep 29, 2018, at 4:04 AM, Felix Meschberger <[email protected]> > wrote: > > Really great news, indeed. > > I don‘t want to crush the party, but doesn‘t this have to go through the > proper IP clearance [1] ?
