WordPress 4.5.1 Is Out Fixing 12 Bugs

WordPress 4.5.1 was released today fixing 12 bugs.

WordPress 4.5.1 is a maintenance release following WordPress 4.5 that has been downloaded about six million up until today.

I warned people to wait a few days before upgrading to version 4.5 as it was a major release. I suppose version 4.5.1 eliminates most of the risk.

This release fixes 12 bugs, chief among them a singular class issue that broke sites based on the Twenty Eleven theme, an incompatibility between certain Chrome versions and the visual editor, and an Imagick bug that could break media uploads.
