Stacks – X includes multiple unique designs inside of one powerful theme, and we refer to these designs as “Stacks.” There are currently four Stacks available in X, with more on the way. It’s like buying one theme and constantly getting access to new designs all the time!
X Theme 3.2.5 – April 28, 2015
This release of X is a simple update to correct a non-critical issue that came to our attention after the previous update was released. When running WordPress v4.2 and saving settings in the Customizer, the save state of the Customizer button was not being set properly. As previously stated, this is not necessarily an update that needs to be implemented based on the situation at hand, and this fix will certainly be rolled into our coming release of the theme. Users who wish to wait for the next release of X are certainly safe to do so if they desire.
