cannam@48: 
cannam@48: Today I'm releasing [version 0.4.1 of Cap'n Proto](https://capnproto.org/capnproto-c++-0.4.1.tar.gz).
cannam@48: As hinted by the version number, this is a bugfix and tweak release, with no big new features.
cannam@48: 
cannam@48: You may be wondering:  If there are no big new features, what has been happening over the
cannam@48: last three months?  Most of my time lately has been spent laying the groundwork for an
cannam@48: interesting project built on Cap'n Proto which should launch by the end of this month.
cannam@48: Stay tuned!  And don't worry -- this new project is going to need many of the upcoming
cannam@48: features on [the roadmap]({{ site.baseurl }}roadmap.html), so work on version 0.5 will be
cannam@48: proceeding soon.

cannam@48: In the meantime, though, there have been some major updates from the community:
cannam@48: 
cannam@48:   * The folks at [CloudFlare](https://www.cloudflare.com/) have produced a
cannam@48:     [Lua port](https://github.com/cloudflare/lua-capnproto) which they are
cannam@48:     [using successfully in production](http://blog.cloudflare.com/introducing-lua-capnproto-better-serialization-in-lua)
cannam@48:     along with the existing [Go port](https://github.com/jmckaskill/go-capnproto).
cannam@48:   * [The Rust port of Cap'n Proto](https://github.com/dwrensha/capnproto-rust) now has
cannam@48:     preliminary RPC support, making it the third language to support Cap'n Proto RPC (after
cannam@48:     C++ and Python), and the second language to implement it from the ground up (Python just
cannam@48:     wraps the C++ implementation).  Check out author [David Renshaw](https://github.com/dwrensha)'s
cannam@48:     [talk at Mozilla](https://air.mozilla.org/rust-meetup-february-2014/).
cannam@48:   * A [Javascript port](https://github.com/jscheid/capnproto-js) has appeared, but it needs help
cannam@48:     to keep going!
