First of all, thanks to everyone for being so helpful with bug reports and even with patches/fixes.
0.3.4 has just been released reflecting a lot of great fixes -- and i think we're well on our way to getting this stable. I'm hoping that the official Beta 3 “stable” release will be out soon. =) Keep those bug reports coming in!
As a quick update, I'm realizing that one of the toughest pain point in upgrading from Beta 2 to 3 is the dropping of ArrayQueryHelper and other utilities to help with the old-style of array-based custom queries.
The next thing I'll work on is to try and get at least part of that functionality back as an OPTIONAL codegenning option, so that for people who are upgrading from Beta 2, they can still take advantage of the custom-written SQL functions they've already written, and so that you aren't necessarily forced into using Qcodo Query. Definitely post back if you have comments, questions or suggestions.
