+1 Me too. Maybe I've missed something obvious, but I'm not exactly
sure (from looking at lighthouse tix) what others are already working
on (don't want to duplicate effort) vs. what might be helpful to work
on (especially any docs that need updating, etc?)
You can help fixing issues on LightHouse yeah, but now Yehuda, Carl
and Adré are putting a great effort to solve some issues on Bundler.
I think now what is blocking the release is that Rails and Bundler
should be delivered both together as RC and Bundler need some more
work.
So perhaps you can help there.
Since nobody else has brought it up, one way you can help is to verify
that plugins work on 3.0, fix any issues that arise, and (most
importantly) report any pain points or bugs that you find in 3.0
itself.
