 # Jira.js changelog
 
+### 4.0.6
+
+- **#347:** Fixed an issue with adding attachments of type `Readable` or `ReadableStream` (e.g., `fs.createReadStream`). Thanks to [Lunatic174](https://github.com/Lunatic174) for [reporting the issue](https://github.com/MrRefactoring/jira.js/issues/347).
+
+---
+
 ### 4.0.5
 
 - **#344:** Replaced the `mime-types` library with `mime` to ensure browser compatibility, as `mime-types` relies on the `path` module from Node.js. Thanks to [kang](https://github.com/kang8) for [reporting the issue](https://github.com/MrRefactoring/jira.js/issues/344) and proposing the fix.
 
+---
+
 ### 4.0.4
 
 - **#320:** Resolved a tree-shaking issue where importing a single client would still include all clients in the output bundle when using bundlers. Now, only the required client code is included. Thanks to [Nao Yonashiro](https://github.com/orisano) for [reporting the issue](https://github.com/MrRefactoring/jira.js/issues/320) and proposing a fix.
