The latest version of Jetpack (3.8) was released earlier this month and can be downloaded now from jetpack.me. Jetpack 3.8 includes Google+ badges, as well as a revised version of the contact form.
The Google+ feature means Jetpack users are now able to add Google+ widgets to their Google+ profile or organisation page. The email feedback form has been restyled and users can now enjoy embedded shortcodes for Twitch.tv, which allows users to insert videos from Twitch.tv using the shortcode [ TwitchTV ].
The Jetpack team have also added new tweaks to the design of Jetpack 3.8, made improvements to the accessibility of the plugin and resolved noted bugs and errors.
