Together with the public release, a new version 0.3.2 is now available which mostly contains bug fixes.
The next release, 0.4.0, is due in about two weeks and still has many open issues but will introduce a number of great features. The Plugin API is going to be locked down, you will be able to mark posts as static pages and apply a bit of SEO to posts using the post settings menu.
According to the Roadmap we will have to wait until Christmas to get our hands on the great dashboard we could see in the Kickstarter campaign.
I am really excited about this platform and look forward to contribute to Ghost and help improving the project!
