Feature images will now be called correctly if you are using a CDN. This function may not work properly if you are deleting the local images from your /data folder after syncing to the CDN. BOTH files must exist (since file checking is done locally), but the user will be served the CDN version.
This release re-arranges the article view page... moving the first post block to within the comment block. In the default skin, there is no appearance difference. However, with some custom skins, you may have to do some extra work to get things to look proper. This change had to be done in order to fix a bug where inline moderation was not functioning properly for the first post.
The categories widget now links to the category from the category title.
Added a widget position for "XenPorta > Articles list: After article". This widget position will allow you to place widgets after each article in your articles list. In addition to this, you could use the included context to limit the widget from appearing based on the iteration of the article. For instance, you could have a widget appear after every third article, etc... Check the FAQ for more information.
Added special RSS feeds for article lists.
Changed some entity relations to help avoid collisions with other addons.
Added an option to auto-fill the custom excerpt text field with the first post message, instead of it just being a placeholder.
Authors can now be created without names/bylines/status. This change was made for compatibility when importing from the old XF1 version.
The included importers now use XF2's built-in step-runner system. That means if you have an extremely large forum, you should no longer get memory time-outs when importing articles and features from the old version.
Major fixes to install/upgrade procedures for those who are upgrading from the XF1 version... I'm honestly amazed that no one has complained about issues till now. But I guess if things have been working out for everybody; its fine...
