You really should read all of the release notes...

What this is saying essentially is that I used to smoothen out a bug in
InterBase but because this has a negative effect in some circumstances I am
simply leaving all exposed to it again.

So, the only difference here is I am making a bug in InterBase visible for
what it is.

To work around it, call InvalidateSQL prior to calling ExecSQL or opening a
dataset.

Also, use a TIB_Cursor and Open so that you are using a cursor instead of an
immediate fetch.
