> Witness the two year lull when Kenton went sandstorming

There wasn't really a lull; development on Cap'n Proto continued that whole time by the Sandstorm team in service of Sandstorm. There was an absence of official releases since Sandstorm always used the latest Cap'n Proto code from git. The same story continues today with Sandstorm replaced by Cloudflare Workers. TBH I should probably give up on "official releases" and just advise everyone to use git...
