There were two security updates released in December. One for Firefox, which is now upgraded to 34.0.5 (a strange version indeed) and Thunderbird which is now upgraded to 31.3.0. Thunderbird update is applied to 14.1 as well, but not for Firefox as 14.1 still use Firefox ESR 31.2.0 and there has been no update for this release.
Meanwhile, two more packages in -current gets an upgrade: groff and grep. Still no interesting activity happening in -current, but let's hope it's worth to wait for the big update. It happened very often in previous releases, but indeed this time, it's taking more time then before. Please be patient and let Pat do his job.
