Introducing Git protocol version 2

The latest news from Google on open source releases, major projects, events, and outreach programs for early career developers.

この規模のリポジトリにとってはメリットありそうな感じかな、なかなかないと思うが。。 For repositories that contain 100s of thousands of references (the Chromium repository has over 500k branches and tags)

Note that git is no longer maintained by linus himself, so it is G sponsored the development...
