WordPress » Improving your plugin – Changelogs announces that a new section will be added to the readme.txt files that plugin authors should use to track changes. As a heavy user of plugins across several different websites this is a very nice improvement. It will make the plugin update that much smoother, as admins will no longer have to go hunting for changes on another website, it will just show up on the plugin upgrade panel. It is things like this that make the WordPress UI so good and why WordPress is my favourite framework. Hopefully authors will start using it.
