Our next scheduled release (tracked by @Ian Joiner) would be April 6th (a week from Thursday). I am not sure if the upstream Arrow changes which fix #1239 or #1226 will have been released by then. I think the Datafusion upgrade in #1249 will be ready however. I would like to plan to delay the release of 0.9 to incorporate those upstream arrow changes if possible @misha @Christian Williams @QP Hou @Florian Valeye @Will Jones @Robert
