Cap'n Proto 0.9
Today I’m releasing Cap’n Proto 0.9.
There’s no huge new features in this release, but there are many minor improvements and bug fixes. You can read the PR history to find out what has changed.
Cap’n Proto development has continued to be primarily driven by the Cloudflare Workers project (of which I’m the lead engineer). As of the previous release, Cloudflare Workers primarily used the KJ C++ toolkit that is developed with Cap’n Proto, but made only light use of Cap’n Proto serialization and RPC itself. That has now changed: the implementation of Durable Objects makes heavy use of Cap’n Proto RPC for essentially all communication within the system.
