Status of 7.9.1

Hi,

Tried to post this via GMANE, but it doesn't seem to have appeared here. Apologies if this ends up being a repost.

Now that 7.9 is officially released, I see that there are now nightly builds
of 7.9.1. I was just wondering what the status of this is likely to be? Are
there likely to be big, potentially disruptive, changes to it?

I'd been tracking the 7.9 nightlies months before the official release, and
just wonder whether I should stick with the released 7.9 for a while, or
continue to track 7.9.1?

Thanks

Andy
