SilverStripe have just released a beta version of their upcoming system 3.1.0.
There's a whole load of new features behind the scenes, but more important there are a few features that will help you out as a site owner.
You can new view the editing window alongside the website view. Edit the content, press save, and see the website refresh in the right hand panel Easy.
You can also navigate your website using the sites standard navigation menus, and the editing window on the left will let you edit the content on that page
Where have all the bugs gone?
We've had a good look through, and are please to find a number of bugs have no gone! And as yet we haven't found any new ones...
We'll continue using SilverStripe 3.0.4 for the time being, as 3.1.0 still isn't officially released, but it won't be long. If you have an existing site built in version, it should be a pretty quick job to update the CMS.
(Upgrading from SS 2.4 is possible, but will take a bit more work as quite a few things changed between these versions)
