Of course, that was assuming no bugs in anything else that went into the 2.5 branch \
late.  Jeroen has been testing 2.5 as itself, and I've been testing the fastmail \
changes rebased on top of 2.5 - and we're both still hitting lots of issues.  I \
pushed another 20 or so patches back today.

I'm really hoping to get 2.5 + our patches into production at FastMail soon, and then \
I'll feel a lot more confident releasing 2.5 proper.  I don't want to give you \
something half-baked that corrupts data - that's the real fear.  So not quite there \
yet, so sorry.

Bron.
