@JessicaSachs @lmiller1990 can we merge this and release a stable stable version of v4. its been more than a year since the last beta was release. since vue3 is now in beta. it would be nice if this gets a stable release.

see #206

[JessicaSachs]

We're very aware that Vue 3 is in beta. We're working non-stop on supporting Vue Test Utils for Vue 3 (vtu-next)

RE Stable: The last decision to make is regarding native typescript support and choosing ts-jest or babel-jest for built-in typescript support. Just added #238 for this. We're busy with Vue 3 support so this hasn't gotten attention.

RE Jest 25.x: I'll look at this PR soon. #237 is on my radar to make this kind of stuff easier

Hi @JessicaSachs , could you please merge this PR, as current version has vulnerability:

[lmiller1990]

I approved. @JessicaSachs we good to merge this and do a minor for vue-jest v3?

[utlime]

Hey @lmiller1990 , it will be good to release for v4.0.0-beta.3 as we started to use beta version

[lmiller1990]

Oh yes, that probably makes more sense @utlime.

I will wait for 1-2 days to see @JessicaSachs opinion. Then we can do it.

I think we should make this 4.0.0 release candidate 1 - I don't see any real benefit in dragging this out. I've been using v4 beta for a while and it seems fine ✅

@lmiller1990 @JessicaSachs . First of all thank you for your great work! Do you have plan to merge it? If so, when community will be able to get it and forget about annoying vulnerability finally? :)

[lmiller1990]

Right now

[lmiller1990]

I will release v4.0.0-beta.3 in an hour or so, waiting on CI and testing a bit.

We need to get into gear and sort this mess out, we have v3, v4 AND v5 (for Vue 3).

Clearly v3 needs to be deprecated, I have literally no idea what the difference is between v3 and v4 (only just joined this repo a month or so ago). v4 seems to work great. v5 (aka next) is also working fine with Vue 3, except source maps are kinda busted, I think. Also no JSX (JSX does not work in Vue 3 yet).

Can someone try upgrading from v3 to v4 and see if anything breaks? It worked fine on my small/medium apps.

[lmiller1990]

Ok 4.0.0-beta.3 should now be available on NPM.
