We hope to have a status report on all of our yearly goals out sometime soon; we had a core team meeting reviewing progress yesterday.

The short of it is "it's all in various stages of development, nothing has hit stable yet." I don't think there's anything major in the next release either, the one after that may or may not have something, we'll see.

You can track the full status here: https://github.com/rust-lang/rust-roadmap/issues/17

The ergonomics initiative is composed of many independent tasks. I don't know if these are all tracked centrally somewhere, but e.g. there's currently an RFC in its final comment period regarding improving the ergonomics of matching references: https://github.com/rust-lang/rfcs/pull/2005
