As mentioned in the biweekly sync call, we are approaching the wished date for the 5.0.0 release, which should happen at the end of next week, or worst case the week after.
Apart from my usual recommendation to take a look at the TODO Backlog at https://cwiki.apache.org/confluence/display/ARROW/Arrow+5.0.0+Release and defer to 6.0.0 any ticket you don't think you will be able to tackle in the next week or two, I think that we also need to start raising the topic of who is willing to be the release manager for this round. At the biweekly call Jorge already mentioned that he might not be able to take care of this release like he did for 4.0.1, so if anyone one else is willing to take over the process I think it would be great to start assessing who might be able to do so. Thanks! Alessandro
