I upgraded to WordPress 3.0.2 just the other day. Now WordPress 3.0.3 is out. This particular upgrade is not critical by any means, but it fixes a bug in the remote publishing interface that allowed authors and contributors to have improper access to certain posts.
As mentioned in the WordPress.org blog, the remote publishing feature is disabled by default. You have to turn it on to enable the feature. You can access remote publishing from the Settings – Writing in the Dashboard.
If you’ve never heard of the remote publishing feature in WordPress, you are most likely not using this feature. So, the question is, is it worth upgrading to WordPress 3.0.3? Probably not, but WordPress upgrades are relatively painless nowadays.
All it takes is a click of a button. It’s as simple as it can get. In any case, I suspect most WordPress users will probably upgrade to 3.0.3.
If you don’t upgrade, no harm will be done, except for the incessant Please update now messages in the WordPress Dashboard. If you can ignore the hounding, you’re a better man or a woman. In my case, I’m upgrading just for this purpose.
It’s good enough reason for me to update to WordPress 3.0.3.
