The first one fixes some old annoyance with device labels and was discussed here:
https://marc.info/?l=freebsd-current&m=138188193523168&w=2

Patched in r259479 on 2013-12-16.

The second one I can't find the relevant mail list discussion for, but it was 
patched in r266107 on 2014-05-15.

Maybe someone else has better luck searching through the mail archives for that
