[Numpy-discussion] 1.8 release
Mon Jan 14 10:45:29 CST 2013
I don't volontear for the next release manager, but +1 for shorter
releases. I heard just good comments from that. Also, I'm not sure it
would ask more from the release manager. Do someone have an idea? The
most work I do as a release manager for theano is the
preparation/tests/release notes and this depend on the amont of new
stuff. And this seam exponential on the number of new changes in the
release, not linear (no data, just an impression...). Making smaller
release make this easier.
But yes, this mean more announces. But this isn't what take the most
times. Also, doing the release notes more frequently mean it is more
recent in memory when you check the PR merged, so it make it easier to
But what prevent us from making shorter release? Oother priorities
that can't wait, like work for papers to submit, or for collaboration
just my 2cents.
