Hi everyone,

I'm pleased to announce the second development release of the gzochi game development framework.

The project description, from Savannah: gzochi (/zoʊ-tʃiː/) is a framework for developing massively multiplayer online games. A server container provides services to deployed games, which are written in Guile Scheme, that abstract and simplify some of the most challenging and error-prone aspects of online game development: Concurrency, data persistence, and network communications. A very thin client library can be embedded to provide connectivity for client applications written in any language. gzochi can be viewed as an application server (plus client) for Guile applications that have special kinds of workloads -- quick, CPU-bound tasks that require transactional guarantees around sending messages and accessing data.

In addition to resolving a number of serious bugs from the first version, this release features:

* Support for an additional storage engine: Berkeley DB [0]

* A remote debugging interface for application Scheme code -- based on wingo's excellent `(system repl server)' module!

* Scalable vector and hash table implementations that support concurrent, transactional modification

* A new example game based on Alan Cox's AberMUD [1]

* ...and more! See the NEWS files in the distribution for details

This is a development release; some important features are still missing. Nonetheless, there's extensive server and client documentation, and the distribution includes two example games with heavily-annotated source code. For more information, visit or check out the project page on Savannah, at -- you can pick up the release from the downloads section.
