[ANN] gzochi project development release 0.6

[Julian Graham]

Hi everyone,

I'm pleased to announce the sixth 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 memory
allocation profile of the server and the portability of the source
code (Mac OS X is now supported). Additionally, it includes:

* Experimental support for two new alternative storage engine
implementations based on hamsterdb and Symas Lightning (LMDB),
respectively

* A more concise syntactic constructor for task and session lifecycle callbacks

* Improved handling of disconnect events in 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.

Special thanks to David Thompson and Maciej Godek for providing
helpful feedback on the gzochi project home page.


Regards,
Julian
