THIS IS THE V2 DEVELOPMENT BRANCH
On this branch, we may make breaking changes to the API at any time. Do not use this branch if you want stability. If you want "1.0 plus bug fixes", use the master branch.
For more, see the 1.0 release announcement:

Cap'n Proto is an insanely fast data interchange format and capability-based RPC system. Think JSON, except binary. Or think Protocol Buffers, except faster. In fact, in benchmarks, Cap'n Proto is INFINITY TIMES faster than Protocol Buffers.
