Do you believe it is acceptable to lose API functionality in a point release without fair warning and with no rationale or documentation? As pointed out in another forum thread, the change wasn't even documented.
There are many of us desperately trying to get our apps converted before the V1 switch off. An unstable API is not making it easier.
If there is a good reason for removing the functionality please document it. If not, please restore it ASAP and *please* stop making breaking API changes in point releases.
