Clearspace 1.3 was released last Thursday. Of note is a new feature which allows you to hide unwanted spaces in the "What's New" list on the front page. It's a great way to focus on the spaces you care about. Also new is a feature which allows you to send a thread, blog post or a document as an email. In the latter case, you can send a PDF of the document. For us, it's been a great way to push content to people outside of our company.
Along with the new features comes a bevy of minor improvements and bug fixes. See the full changelog for the details.
