Clarify 1.0.0 release

[joepvl]

Just noticed version 1.0.0 was released on npm. I compared the package code; the changes seem to be the addition of TS definitions, a fix introduced in 459c652 ("Fixes currentListeners initialization"), a notice added to the README, and I suppose the fact that it's considered stable now by virtue of bumping to a major version.

I guess I'm just asking for "official" confirmation, as I came here expecting to find a GH release or CHANGELOG entry listing changes and possibly giving some extra info or clarification. Thanks!

Yeah, mostly just TypeScript.

Since the package had been in 0.0.1 for two years now, I just figured maybe it was time to move it to stable 😛

@arcanis I'm here for the same reason - it would be great if you could add release notes either as a CHANGELOG.md file in the repo, or on the releases page. This package has been very useful for me - thank you for your hard work!
