Are you working on this @pcmoritz?

Philipp Moritz / @pcmoritz:
@holdenk I submitted a WIP version of what I have so far; it works but needs some profiling. Unfortunately I won't have time to work on it before next week, feel free to try it out and let me know what you think/keep developing it in the meantime.

Wes McKinney / @wesm:
I moved this to 0.11. If it gets merged before 0.10, that's fine, but since Ray (where this would be most immediately used) does not use Arrow's versioned releases they aren't blocking on getting this into 0.10

Brian Hulette / @TheNeuralBit:
It looks like this was actually merged for 0.10 (and certainly not JS-0.4.0) - is it too late to update the fix version?

Brian Hulette / @TheNeuralBit:
I think the same thing happened in ARROW-2940, ARROW-2451, ARROW-2437, ARROW-2458, and ARROW-2397 - I went ahead and updated them all. It looks like these mistakes prevented them from being added to CHANGELOG.md for v0.10.0

Brian Hulette / @TheNeuralBit:
@wesm not sure if you saw this - I think the issues I mentioned above were incorrectly marked with fix version JS-0.4.0 rather than 0.10.0. I've fixed them in Jira now, but I don't think they made it into the CHANGELOG.md as a result. Is there anything we can/should do about that now?

Wes McKinney / @wesm:
We can definitely generate the changelog. ARROW-3132
