Automattic, Inc has released an update to their WordPress application for the BlackBerry PlayBook. This update is to version 2.1.5 from 2.1.3, so as you can see it is not a huge update. One could assume that this update is just for some bug fixes and nothing more.The all new WordPress for PlayBook™ app allows you to write posts, edit pages, and manage comments on the go. Both WordPress.com and self-hosted WordPress (2.9.2 or higher) sites are supported. Download the app and start blogging on the go in no time.
