7.8 Release Update

The time is here! We'll be closing off new features this week. There
are some exceptions that have been made already:

 * Geoffrey will get SIMD/Template Haskell in this week, as he's been
a little busy. But it's very close.
 * I believe Trevor and Iavor would still like to get Kinds without
Data in the release, but Simon is currently on leave for the next few
days, so we'll see once he gets back to look into it.

There are some other lingering potential features that might make it
(of various sizes,) but it's not clear they will be done in time.
We'll be going on a case-by-case basis as I said. Do you have a
feature you'd like to see make it in? Did you write a patch for some
super cool feature? Please email me (either on list, or off-list) and
we can discuss it.

Again, today isn't a hard-line requirement, but at this point, I
*have* to be aware of what you're doing, for you to have any chance of
making the merge window. Several people have already done this, and
we're discussing it.

If you have a patch, but you're in doubt if it is too big, just email
me. Or get ahold of me on IRC (thoughtpolice.) You can't really waste
my time on this note.

And of course, please continue to liberally report bugs (or patches!)
- it's much better if we find them as early as possible.
