+author: kentonv
+---
+
+Today I'm releasing [version 0.4.1 of Cap'n Proto](http://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 month?  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!
