  *   Next ET release manager search:

Roland sent email to people asking: “are you willing to be the release manager?”.

Yosef suggested that there should be a release team with a coordinator more than a release manager in charge of everything.
Being the release manager shouldn’t be too difficult because Zach in the last release created detailed notes about the process, also he pointed out some stuff in release list that only Steve or Roland can do like updating ZENODO site.
 It was decided to wait for one more week if not  Steve volunteered  to do it if Roland does the next one.
