GCC 5 now the default in wily (release pocket)

GCC 5 is now the default in the wily release pocket, together with some
libraries, which were either forced (icu, boost1.58), or migrated on their own.
 The majority of the packages in -proposed are still blocked by missing rebuilds
or packages failing to build.

The packages which already are migrated to the release pocket should be
installable and not break any installation, however using the release pocket for
development which touches any of the not yet migrated packages won't work.  For
this case you should have a development chroot with both the "release" and  the
"proposed" pocket enabled.

We do *not* recommend updating your default environment to wily-proposed. If you
want to help with testing one of the desktop environments, please do that in a
VM or in a chroot. The Ubuntu desktop already seems to be upgradable.  Updates
of Kubuntu, Xubuntu and UbuntuStudio desktops are not yet tested.  Feedback is

To get this large transition finished, your help is welcome and needed.

What you should *not* do:

 - Starting a major transition / update of some package or
   set of packages.

 - Merging or force syncing a package from Debian which had a library
   transition in Ubuntu but not in Debian. We'll see to these packages
   after the majority of the packages moved to wily.

What you should do:

 - work on a transition mentioned at [1]. Pleases coordinate with
   release managers on IRC (#ubuntu-release).

 - Relevant FTBFS are tracked on [2]. Help with those is greatly
   appreciated to unblock library transitions.

 - With a lower priority, fixing build failures and dep-wait's
   mentioned at [2]. Check that page maybe not as often as your
   email, but do it on a regular basis. Unfortunately we had to
   start the GCC 5 changes with a rather long list of issues.

Remember that this transition doesn't end at the main/universe border or at the
set of packages included in our iso images, but involves the whole archive (like
any other transition).

Thanks, Matthias
