[upgrade-interactive] Add a flag for pre-release

Feature

What is the current behavior?
Only shows non-prerelease versions.

Would be useful for instance to upgrade all related packages to Babel 7 alpha.

What is the expected behavior?

$ yarn upgrade-interactive --include-pre

It should then include pre-releases as well.

Any news on this?

Also, I'm wondering if the --latest flag really use the latest tag of the repository or simply use the version with the higher semver…

Shouldn't be too hard to get a PR out for this if anyone is curious.

Has this been fixed? When I do an "upgrade-interactive --latest" it does show pre-release beta versions as well.

I would like to work on this issue and I already had a look at the code for upgrade-interactive. Seems not too hard to modify. Can someone guide me on what exactly needs to be changed here.
Thanks

I would be interested in this as well - I'm currently using an alpha of istanbul to generate code coverage for ES6. Running yarn update --latest downgrades the installed version without warning, even though it is specifically pinned:

yarn upgrade --latest
git diff package.json
# -    "istanbul": "1.0.0-alpha.2",
# +    "istanbul": "0.4.5",
