summarystat = median

@chriselrod is this a typo? Did you mean minimum?

[chriselrod]

Yes, it should say minimum. I briefly considered making median the default because I think there should be some penalty for noise. But changing it may be considered breaking. And most users would expect the minimum to be the default, so I figured it's probably the better choice anyway.

I'll probably make another PR where I just record minimum, median, mean, and maximum, adding each to the benchmark_result. Then the plot function will let you choose which.

[chriselrod]

Let's hold off on making a release until I do that. Removing an argument (summarystat from runbench is breaking, so let's just not make a release with it.

Ha, that was close!

[DilumAluthge]

Good thing we don't instant merge.

FWIW, if it had been merged, we could have just yanked that version, so it wouldn't have been the end of the world. But better to not have merged in the first place 😉
