Basically the old maintainer (Marc) got less time halfway between 6.6 and after the 7.0 alpha. (which was D2009+ and FPC compat)
A new maintainer took over, and I did some fpc related patching.
Since 6.6 is very old and 7.0 testing is well, testing. My opinion is to forget about labels and test them yourself.
btw, I'm using the old 7.0 alpha in production, and that is reasonably fine. I plan to update it to trunk in the coming months, and at the same time to go
from Delphi XE to Lazarus.
