hi folks, It's been about 5 weeks since the 0.4.1 release, and we've completed quite a lot of additional work (about 90 patches) in Apache Arrow. >From the look of JIRA we can likely everything essential by the end of this week and make a 0.5.0 release candidate on Sunday or Monday.
The umbrella JIRA for the release is https://issues.apache.org/jira/browse/ARROW-1052 -- please attach release blockers so we can stay organized over the next several days. Thanks! Wes
