docs/extensions/core-concepts/changelog-txt.md
WooCommerce extensions use a standard changelog format. A changelog.txt file is required for extensions on the WooCommerce Marketplace.
Your changelog.txt file should look like this:
*** WooCommerce Extension Name Changelog ***
YYYY-MM-DD - version 1.1.0
* Added - Useful new feature
* A second new feature
* A third new feature
* Fixed - Important bug fix
* Update - Compatibility with latest version
YYYY-MM-DD - version 1.0.1
* Fixed a bug
YYYY-MM-DD - version 1.0.0
* Initial release
To showcase the different types of work done in a product update, use any of the following words to denote what type of change each line is:
Items indented under a specific entry type can nest additional changes of the same type in a single-level list.
This is how a parsed changelog appears in a modal on WooCommerce.com, with each entry type replaced by an icon. Changelog entries without a type are displayed with the Other icon, while nested entries have no icon.
