Hi,
Yes, I didn't put them in because I changed the functionality in 2/13
and there is a bug fix in 5/13. I thought you might want to do a quick
diff of the git v6->v7 tree.
Although given that most of the changes were in response to your
comments in v6 I probably should have just put the tags in.
Thanks,
