Textpattern, the CMS that powers this site, recently released version 4.0.6 and with it comes numerous improvements, fixes and a few additions (and deprecations). Nothing particularly ground breaking but it’s still a good and it seems necessary update, based on the fixes made. From the TXP blog:
We have fixed no less than six security issues. Because half of those can be used from the public side, updating is strongly recommended.
A few plugins may need to be updated as well. So with all that said, if you are TXP user, take the time to update as soon as possible.
