I think we have learned that without the drive of someone solving a problem they have, we never close on the issue. The successful API work has involved a real problem and a header file proposal to focus the discussion. > We may also have time to expand on this as part of the June Sprint. > Agree, but again we need some thing to anchor the discussion. A sprints purpose is to focus on solving specif problems, we can discuss generally in HOs and on the list I think. With a proposal that outlines the issues to be solved (not starting a general discussion) I am in favor of adding it to the agenda. > > Bill > > On Fri, May 8, 2015 at 6:58 AM, Mike Holmes <mike.hol...@linaro.org> > wrote: > >> Gabor >> >> If you have a proposal for the API, 1.2 is scheduled for the end of this >> quarter.
