The software has been successfully ported to the Mac as well as Windows NT/95 - we'd like to test those ports better and make sure they work as they should.
We have a new and better version of the frontend server on the drawing board. Resources and external commitments will govern when we'll be able to do something real with it. Fetures should include greater flexibility, greter support for access/resource control, and easy support for Explain (possibly with Zebra as an extra database engine).
We now support all PDUs of Z39.50-1995. If there is one of the supporting structures that you need but can't find in the prt*.h files, send us a note; it may be on its way.
The 'retrieval' module needs to be finalized and documented. We think it can form a useful resource for people dealing with complex record structures, but for now, you'll mostly have to chew through the code yourself to make use of it. Not acceptable.
Other than that, YAZ generally moves in the directions which appear to make the most people happy (including ourselves, as prime users of the software). If there's something you'd like to see in here, then drop us a note and let's see what we can come up with.
