[ANN] gzochi project development release 0.5

[Julian Graham]

Hi everyone,

I'm pleased to announce the fifth 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.

This is primarily a bug fix release, focused on improving the
stability and correctness of durable task scheduling and transactional
access to data. Additionally, it includes:

* A new scalable data structure in the Scheme API, based on SRFI-44
sequences: gzochi:managed-sequence

* Reporting of average transaction duration via the server's embedded
administrative web console

* Performance improvements to both the server and reference client
implementations

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

This is a development release; the framework is largely
feature-complete but likely not bug-free. Nonetheless, there's
extensive server and client documentation, and the distribution
includes two example games with heavily-annotated source code. For
more information, visit http://www.nongnu.org/gzochi/ or check out the
project page on Savannah, at
http://savannah.nongnu.org/projects/gzochi/ -- you can pick up the
release
from the downloads section.


Regards,
Julian
