Add lerna changelog

[hzoo]

From other PR (#23) - Didn't get to updating the readme but I would do that as well

To run it, currently I'm checking out the branch,

GITHUB_AUTH=public_repo_auth_key_here GITHUB_ORG=babel GITHUB_REPO=babel ./node_modules/.bin/lerna changelog

---

Example changelog: https://github.com/babel/babel/releases/tag/v6.7.0

Then we go in and manually add code if useful, and summary/explanations

---

I've been using this for the babel changelog

[hzoo]

TODO: figure out what to do with the hardcoded github tags (labels) https://github.com/kittens/lerna/pull/29/files#diff-98b51ca511528ecc68ea54d6adbf8f6bR8

[hzoo]

rebased to master

Potential changes to make:

• Use headings instead of bullets for the tags (less indentation, looks better)
• Incorporate issues fixed if in the body/title (phab, github)
• Auto link to issue if (fixes T123 or fixes style(typo): seperated -> separated #123)
• add list of contributors at the end, total
  • add how many previous PRs or if first contribution
• time between pr and merge, between issue and fix, etc
• fix comma spacing (was a,b)
• auto prepend to changelog? https://github.com/npm/npm/pull/11077/files#diff-4590fb6647766d4997c23f58054b47a3R7

Other

• After publish, leave a comment on each merged PR that it was released in version x.x.x)

Whoa, this is cool! Would definitely like to use this feature.

[hzoo]

Yeah, we're using this as a baseline for the babel changelog https://github.com/babel/babel/releases

@hzoo have you considered using an existing changelog package like conventional-changelog?

All you have to do is create the changelog first, then git add it, then run lerna.

[cdaringe]

that's pretty cool, @ahfarmer!

We currently had to integrate lerna with commitizen and semantic-release.
There is a Commitizen Lerna adapter here: https://github.com/atlassian/cz-lerna-changelog
And a lerna-semantic-release package here: https://github.com/atlassian/lerna-semantic-release
Currently we are not generating a changelog, yet, as semantic-release is tightly coupled to git, but potentially some of the work we did can be reused for this ticket.

Moved to a standalone repo https://github.com/lerna/lerna-changelog so gonna close
