Git roadmap (How read What's cooking in git.git)

Hi Junio, I'm starting a french blog[1] on git to support workshops[2]. The goal is to explain deeply the philosophy, the commands and subcommands, workflows, etc. And also to aggregate headlines of the git world, follow events and announce git releases. For the latter, it's a bit hard (for a non core developer) to follow the development. From your point of view, how we could set up a roadmap and a "what's new"?
