3.0.0-alpha3 release status update
Hi folks,
We're planning on releasing 3.0.0-alpha3 next month (May 15th). The biggest
piece of work targeted for this release is completing user-facing erasure
coding changes. This is on track, but there are some other blockers that we
also need to push on.
I've also written a new status update on the wiki, also reproduced below.

Thanks everyone for their hard work thus far!
Best,
Andrew
