The 20th of June 2009 was the day when changelogs found their way into readme.txt files of plugins in the WordPress plugin repository. Thanks to Peter Westwood und Mdawaffe a new version of the readme.txt example file was available online that had an example of the changelog in action.
For many many people a changelog is a very important thing; it is all about justifying to your users why they should upgrade to the latest version of a plugin. Changelogger shows the latest changelog right on the plugin listing page, whenever there’s a plugin ready to be updated.
Note: The inline changelog on a plugin update shows up if the plugin author added a changelog section based on the new <a href="https://wordpress.org/extend/plugins/about/readme.txt" title="readme.txt example file" rel="ugc">readme.txt example file</a> to their plugin’s readme file.
