The GNU C Library will be rebased in F21 to match glibc 2.20.

[Carlos O'Donell]

Fedora,

This is a reminder that the glibc team will be rebasing
glibc in F21 to match glibc 2.20.

The plan remains largely as was written here:
http://fedoraproject.org/wiki/Changes/GLIBC220

Only glibc 2.20 has ABI guarantees, and therefore we
will move to 2.20 before F21 goes to GA to ensure that
F21 has a strong ABI guarantee.

I expect this to be the process forever going forward:

* Rawhide tracks glibc master.
* Fedora release is branched from Rawhide.
* glibc release is made upstream.
* Fedora branch is rebased on glibc upstream release
  to include ABI guarantees.
* Fedora release goes GA.

The changes in the rebase should be minor since we've
been tracking master the whole time.

Cheers,
Carlos.
