Hi *,

To get things back on track, we have a short post following up the
earlier one this week. It's been busy today so I'll keep it short:

  - The STABLE freeze Austin announced two weeks ago is happening now,
although at this point a few things we wanted to ship are just 98%
ready. So it may wait until Monday.

  - HEAD has been very busy the past two days as many things are now
trying to merge as closely to the window as possible. Some notes
follow.

  - Gergo Erdi merged the implementation of pattern synonym type
signatures: https://www.haskell.org/pipermail/ghc-devs/2014-November/007369.html

  - HEAD now has support for using the 'deriving' clause for arbitrary
classes (see #5462).

  - HEAD now has a new flag `-fwarn-missing-exported-sigs`, which
fixes #2526. See https://phabricator.haskell.org/D482

  - HEAD now has 64bit iOS and SMP support for ARM64, thanks to Luke
Iannini. See #7942.

  - HEAD no longer ships `haskell98`, `haskell2010`, `old-locale` or
`old-time`, per our decision to drop support for `haskell98` and
`haskell2010`. GHC 7.10 compatible releases of `old-locale` and
`old-time` have been released on hackage. See
https://www.haskell.org/pipermail/ghc-devs/2014-November/007357.html
and https://www.haskell.org/pipermail/ghc-devs/2014-November/007383.html

  - `base` now exports a new module for Natural numbers called
`Numeric.Natural` following Herbert Valerio Riedel's recent proposal.

  - HEAD should finally be compatible with LLVM 3.5, AKA #9142. The
patch from Ben Gamari is at https://phabricator.haskell.org/D155

  - Your author has been busy and delayed due to some bad travel
experiences the past week, so the 7.8.4 RC1 hasn't landed this past
week. Hopefully it will be out by the end of this week still.

Since the last update was only a few days ago, you'd think we haven't
closed a lot of tickets, but we have! Thomas Miedema has been very
very persistent about closing tickets and cleaning them up, which is
greatly appreciated: #9810, #8324, #8310, #9396, #9626, #9776, #9807,
#9698, #7942, #9703, #8584, #8968, #8174, #9812, #9209, #9220, #9151,
#9201, #9318, #9109, #9126, #8406, #8102, #8093, #8085, #8068, #8094,
#9590, #9368, #2526, #9569, #8149, #9815, #5462, #9647, #8568, #9293,
#7484, #1476, #9824, #9628, #7942
