This is the current list of 0.6.0 PRs that we’re trying to merge:
https://github.com/JuliaLang/julia/pulls?utf8=✓&q=is%3Aopen%20is%3Apr%20milestone%3A0.6.0%20
Some of these are not breaking so can happen after feature freeze – about half of them are behavioral changes and need to get merged first. Fortunately, they’re all pretty far along.
