 ## [Unreleased]
 
+## [0.4.0] - 2019-04-02
+
 * Packages names have been lowercased and invalid characters will be removed to prevent errors when Composer 2.0 is released ([#90](https://github.com/cedaro/satispress/issues/90)). This may require updates to `composer.json` if your project requires packages with uppercase characters.
 * Refactored authentication servers to prevent conflicts with plugins that call `determine_current_user` earlier than expected ([#94](https://github.com/cedaro/satispress/issues/94)). This changes the server interface and will require code updates if you're using custom authentication server.
 * Introduced a default logger implementation to surface issues in `debug.log` when debug mode is enabled. By default, only messages with a `warning` level or higher will be logged ([#86](https://github.com/cedaro/satispress/issues/86)). 
@@ -35,7 +37,8 @@ Major changes include:
 * [Capabilities](docs/security.md#capabilities) were added for viewing and downloading packages, as well as managing SatisPress options. Only administrators have access by default.
 * The storage layer was abstracted to make it swappable.
