deprecated core-js

[pierroberto]

Hi Team,

Do you have any plan to upgrade core-js in the next release?
I get this warning:

redux-saga-test-plan > [email protected]: core-js@<3 is no longer maintained and not recommended for usage due to the number of issues. Please, upgrade your dependencies to the actual version of core-js@3.

Thanks

Is there any chance this can happen? I am using a package that is using this and is throwing a pretty scary warning.

npm WARN deprecated [email protected]: core-js@<3.3 is no longer maintained 
and not recommended for usage due to the number of issues. 

Because of the V8 engine whims, feature detection in old core-js versions could 
cause a slowdown up to 100x even if nothing is polyfilled. Please, upgrade your dependencies
to the actual version of core-js.

Any movement on this? There's a greenkeeper PR for this that has been continually updating since March 19 of 2019. Off all the outdated dependencies, this is the one that has real downstream effects on consumers of this library.

Any idea when is this gonna be released? (Or at least which type of release this will be (fix|feature|breaking change)?

@brumik I think core-js has been removed from latest 4.0.5.

@jp928 When pulling 4.0.5 I am still getting these deps in node_modules/redux-saga-test-plan/package.json

  "dependencies": {
    "core-js": "^2.4.1",
    "fsm-iterator": "^1.1.0",
    "lodash.isequal": "^4.5.0",
    "lodash.ismatch": "^4.4.0",
    "object-assign": "^4.1.0"
  },

@brumik thanks for getting back. I will fix this soon.

@jp928 Are there any news on this?
