upcoming rhythmbox release

[Jonathan Matthew <jonathan d14n org>]

Hi,

I'm going to release Rhythmbox 3.4.3 around 9:00 UTC on January 6.  Strings are
frozen until then.  There have only been a few UI string changes since 3.4.2
over a year ago, so many translations are up to date, but there have been
significant changes in the user guide.

thanks,
Jonathan
