The 2.8.0 release didn’t contain everything I wanted. So, two new features in a minor release? Certainly!
First, there’s now a fallback Social Image uploader.
Second, when scheduled posts are published they now trigger sitemap cache flush pinging.
Moreover, this update fixes a few bugs: namely ones that caused character encoding issues in the admin area.

This update fixes a corner case bug regarding PHP mbstring. If you haven’t read the 2.8.0 upgrade notes yet, please do.

This major release not only fixes various bugs, but also introduces new options for you to fiddle with.
You’re now able to adjust General Settings easily! These settings include options to adjust the cache, (re)move the SEO Bar, and set a Canonical Scheme.
Google’s Knowledge Graph has been transformed into something much bigger last year, so the related settings now fall under a new name: “Authorized Presence”.
You can now select your website’s social images. With this much asked for feature, you’re now really in control.
You can now also control the style of your sitemap. The sitemap title will link back to your homepage when clicked upon.

This update makes sure no conflicts arise anymore with WP Engine’s staging services when WordPress is at a major version release.

While the 2.7.1 release went very well, both that update and 2.7.0 still had an issue unresolved.
This update makes sure this plugin will run on PHP 5.2 once more by moving one little function call into a variable.
