You may have misunderstood. Version 3.0
We jumped ahead as a beta for Version 7, and we should not have done so. We (I) lack the technical skills to offer any useful feedback to the AC staff on the beta software. As soon as it got running it was evident we would not be able to use it for any billing, and so we never did. There was an update to the Beta, that fixed some small issues that we did not have, so I never upgraded. Before the Beta 7 we were not on 6.3.3 ever if I remember correctly.
But at times like these I reflect back on how happy I was with an update, and the last time I had that feeling, was about Version 3.0
Martin,
I followed the yearning for v3.
I was suggesting 6.3.3 as it is the current stable release we recommend for our clients. The only folks we have installed 6.5.6 for are folks who want certain features, an are willing to live with the problems.
Besides the issues already documented, one of those 6.5.6 sites needed some patient data imported, and during the data import the utility crashed and corrupted the AC install. Not lethal, but pleasant and disruptive. YMMV
