| Today I'm releasing [version 0.4.1 of Cap'n Proto](https://capnproto.org/capnproto-c++-0.4.1.tar.gz). |
| As hinted by the version number, this is a bugfix and tweak release, with no big new features. |
| |
| You may be wondering: If there are no big new features, what has been happening over the |
| last three months? Most of my time lately has been spent laying the groundwork for an |
| interesting project built on Cap'n Proto which should launch by the end of this month. |
| Stay tuned! And don't worry -- this new project is going to need many of the upcoming |
| features on [the roadmap]({{ site.baseurl }}roadmap.html), so work on version 0.5 will be |
| proceeding soon. |
| |
| In the meantime, though, there have been some major updates from the community: |
| |
| * The folks at [CloudFlare](https://www.cloudflare.com/) have produced a |
| [Lua port](https://github.com/cloudflare/lua-capnproto) which they are |
| [using successfully in production](http://blog.cloudflare.com/introducing-lua-capnproto-better-serialization-in-lua) |
| along with the existing [Go port](https://github.com/jmckaskill/go-capnproto). |
| * [The Rust port of Cap'n Proto](https://github.com/dwrensha/capnproto-rust) now has |
| preliminary RPC support, making it the third language to support Cap'n Proto RPC (after |
| C++ and Python), and the second language to implement it from the ground up (Python just |
| wraps the C++ implementation). Check out author [David Renshaw](https://github.com/dwrensha)'s |
| [talk at Mozilla](https://air.mozilla.org/rust-meetup-february-2014/). |
| * A [Javascript port](https://github.com/jscheid/capnproto-js) has appeared, but it needs help |
| to keep going! |
