Interesting that they took to the Google blog to announce this; is there a corresponding LKML post?

I thought google uses hg, have they switched over to git as well?

For all the "big" Google projects they use a proprietary system called piper.

I think all their open-source stuff (Angular, GoLang, Android) uses git (and sometimes Gerrit).

Although given Google's scale, I'm sure there's some teams/projects that use Mercurial.

This is disgusting. So little forsight in the past... At least the outcome of quite useful.

Go started on Mercurial and then eventually moved into Git.

Git didn't have a proper version number or extensibility field in its protocol? That's quite a bit of hubris.

IIRC, they were in a serious time crunch when they drafted/made git. I can't remember the whole story...

Or, more likely, an oversight.

AIUI, the git ssh protocol is just the git protocol tunnelled through ssh. So why do they need different mechanisms for signalling V2?
