Automattic developers have released an updated edition of Jetpack plugin set for the users of WordPress blogs.

This is mostly a bug fix edition.

Changelog:

The expected modules get reactivated correctly during unusual upgrade paths. I’m looking at you, Sharing Module.
Theme compatibility (in particular the Koi theme) has been improved for subscriptions.
A reference to an unused CSS background image has been removed.
Subscription requests are no longer sent during spam comment submissions. Who wants spammers subscribing to your site anyway?

Jetpack for WordPress brings a couple of features that are offered on the WordPress.com blogging platform. We use it here on TechWhack and it is a pretty good add-on to have!
