Important WordPress 4.0.1 go update!
WordPress 4.0.1 has been released, with backward patches for many WordPress versions. It’s a vitally important update, because 4.0.1 is a security release containing not only some small (but important) security updates, but also releases to fix a major issue with pre-4.0 code. It’s also important everyone tells everyone to update.
I have seen a few peeps telling people not to update as it will cause problems this might be true but it’s really irrelevant as it will definitely cause you problems if you do not.
So what is this issue exactly?
So how does it actually work?
Unfortunately, this update may mean you temporarily lose functionality in some plugins, due to some plugin developers making use of the functions previous flexibility to parse short codes to their own functions, rather than making use of the Short code API. Fortunately many of these developers will be correcting this and releasing updates as soon as possible.
But I leave you with one thought. Isn’t it amazing how far WordPress has come and how mature the eco-system has become? While it’s true that this is a serious vulnerability, it’s been handled really well by the WordPress.org team on the support forums, and most updates have gone smoothly. This style issue even a couple of years ago would have been disastrous, with system admins frantically patching systems and people begging others to update. Many 3.7 or higher sites had updated before I’d git committed latest changes to my own site.
Now we just need to get the rest to upgrade anyhow the short video is for any sys-admins out there who need a reminder as to why we update our WordPress sites!
