Version 0.5 was released on July 7th, 2015.
Comments are now allowed on plugin pages via the third party disqus. This is an experimental feature and the comment system may change down the road.
Markdown is now supported for use on your plugin's descriptions and release notes using Github flavored markdown.
Url's on the Webstore are now hashtag-less! So once where a page may have been /#/plugins/categories, you can now view it at /plugins/categories. Note that this is a breaking change if you had bookmarked or linked to any pages using the old hashtag style url's.
Custom configuration is now supported and has an API that allows you to pull strongly typed deserialized objects or just to cast certain fields as specific types. Also supported is client viewable settings and encryption.
