That is correct. I see now that the deprecated message in the source was
never corrected. The decision was made quite some time ago, and partially
also because there was a lot more involved than I initially thought.

The same division line will also change the buffer type to Pbyte. This can
already be abstracted by using TRecordBuffer as much as possible.

2.7.0 (2.7.x) is the safe version to make the break. The change happened in
trunk long ago, and anything newer will get a higher number.
