Changes look great, thank you!

I'll hold on with merging until the others are ready to, in case we missed something. We might also combine it with the switch to ES Modules at the same time

[gr2m]

can you bump the peer dependency version of semantic-release

  "peerDependencies": {
    "semantic-release": ">=18.0.0-beta.1"
  },

Update: done via a226c81

[gr2m]

I decided to go the beta release route after all, it will make it easier to discuss the more complex pull request at #247
