Even though Wordpress can be set to auto update you still need to keep up to date with:
- core updates
- which of your plugins are compatible with core updates
- which of your plugins and themes need updating (Wordpress does not update themes and plugins automatically)
- what plugins are under attack by hackers
- if Wordpress in general is under attack by hackers
This thread is for update notices from Wordpress.org and any notices elsewhere that there is a problem with Wordpress core programming or a plugin.
Some of your sites built using Wordpress may be set to automatically update the core Wordpress program but this does not update your plugins or 3rd party themes. It is a good idea to check manually that everything is up to date every once in a while.
