[ANN] gzochi project development release 0.3

Hi everyone,

I'm pleased to announce the third 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 clients) 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 version
0.2, this release features:

* Automatic retry for failed application transactions

* Support for time-bounded transactions that maximize concurrency and throughput

* Simplifications to the syntax for creating new managed record types
(which are extensions to Guile's R6RS records implementation)

* A reference client implementation that integrates easily with a GNU
GLib "main loop" [0].

* ...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.
