Acorn at version 7.0.0

[ile]

When I installed the latest acorn-node (2.0.1), I get acorn 7.4.1 with it:

{
  "name": "acorn-node",
  "description": "the acorn javascript parser, preloaded with plugins for syntax parity with recent node versions",
  "version": "2.0.1",
  "author": "Renée Kooi <renee@kooi.me>",
  "bugs": {
    "url": "https://github.com/browserify/acorn-node/issues"
  },
  "dependencies": {
    "acorn": "^7.0.0",
    "acorn-walk": "^7.0.0",
    "xtend": "^4.0.2"
  },

Any change of updating the dependencies? Acorn 8 supports JS syntax that would be useful.

Does acorn 8 have the same engines support as acorn 7? If not, updating to it would be a breaking change.

Wouldn't it be time to update Browserify?

Breaking changes are always the most costly changes for the ecosystem and are always best avoided. What are the breaking changes in acorn 8?

I was looking for the optional chaining syntax, but I see it's supported in acorn 7.3.0 already. But it needs ecmaVersion set (acornjs/acorn#1010) and it seems that it's not set high enough.

Not sure if it can be set at the browserify level, but I suppose it can't.

I don't know about breaking changes.
