[milestone] M5 code freeze in effect

[Tim Ellison]

A reminder that the code is now frozen, meaning we are all testing and 
discussing must-fix bugs that have a serious impact on declaring the 
milestone.  Applying the code freeze ensures that we are not trying to 
test a moving target.

As before, defining a bug as "must-fix" in this milestone requires (at 
least) two committers agreement.  Of course, everyone's opinion about 
the seriousness is encouraged, and if the fix is not deemed to be 
trivial then people are encouraged to seek a community review before 
committing it -- again to preserve stability.

We aim that this freeze period is no more than a week, but we will move 
the release date if necessary to achieve the required quality.

In the meantime, if you really don't want to help testing (and I hope 
you will!) feel free log patches in JIRA, or if the work is too large to 
manage as a patch we can discuss creating a branch for a sandbox.

Regards,
Tim
