Make a new release?

[fornwall]

If possible, it would be nice with a new release to get the hashbrown update out, which fixes building with latest nightly (tkaitchuck/aHash#183).

I wanted to release with this change #51, but if it is urgent I can make a new string-interner release before that.

Thanks! It's not urgent for us, we just switched to a git snapshot of string-interner for now to fix the build with nightly rust.
