Thanks for the SQL update, I'll try processing that shortly....
How far on the horizon is 1.9.6.2? The digests are of great interest to me as well if they are working correctly. Is there a 1.9.6.2 beta or is it still under strict development?
At any time, you can pull a copy of the source code and compile it yourself, but keep in mind - the source is a 'snapshot' of the current programmed state of YAF. It is NOT recommended for production server by any means - due to the fact that there can be unfinished segments of the code at any time. Additionally, bugs that are found in source versions get addressed as developers have time during that release cycle - so if you do find a problem, developers can not promise a fix or a time for that fix. You would have to wait until something is available.
On the flip side of that, if you do pull, compile, and run a source version, it is highly appreciated if you do lodge bug reports or issues here on the support forums or on the BugTracker so that developers do know of the problem and can address it. It's just not recommended to run a source version on a production server because if there is a problem, your forum could be in-accessible until a fix is made available - so downtime could be a problem.
Unfortunately, developers are not able to provide an update release schedule, due primarily to YAF being a community developed project, so speed of development depends entirely on developer availability. I try to provide forum support so the developers have more time to concentrate on code while I handle many of the simpler problems YAF users and admins might encounter.
At this time, I have a source version running on one of my production users, but we do not utilize the digest feature, so I cannot comment on it's availability, stability, or function. I do anticipate bringing another development server online where I can test features like that and help in tracking and development.
