This release fixes one of the biggest bugs with asynchronously embedding Neovim (some input states would just block the API), and makes ActualVim more reliable as a result. Neovim embedding works pretty well now, and will only get better. I'm hoping it will be possible soon to embed the entire Vim experience into another editor with little to no tradeoffs on either side. I've been impressed when interacting with the Neovim developers.
I'd love to see neovim embedded in Firefox, and have it be just a standard part of every text field. Having a seperate editor window pop up as with the It's All Text extension is just not the same.
It'd also be great if there was a way to have neovim "wrap" arbitrary shell commands, kind of like rlwrap[1] does, only with full vim editing features available instead of the relatively crippled readline.
I wish something like this were available for Chrome. My Firefox use has been declining. Not really sure why. Though the termination of the addons language (xul?) in favor of webextensions is probably a big reason.

I'm hoping it's ported to Firefox when webextensions are ready.
