 # Changelog
 
+## v0.5.0 (2024-05-28)
+
+[All new commits](https://github.com/princeton-nlp/SWE-agent/compare/v0.4.0...v0.5.0)
+
+✨ The big news is our [brand new documentation](https://princeton-nlp.github.io/SWE-agent/) ✨
+
+Secondly, @ollmer added a new flag `--cache_task_images` that will significantly speed up SWE-agent when running on the same environment/repository multiple times (no more waiting for cloning and installation!)
+
+### Breaking changes
+
+* Remove direct imports in __init__.py (you can no longer `from sweagent import Agent` by @klieret in https://github.com/princeton-nlp/SWE-agent/pull/436
+* We have reformatted our codebase. If you create a PR based on a previous commit, make sure you install our `pre-commit` hook to avoid merge-conflicts because of formatting. See [our docs](https://princeton-nlp.github.io/SWE-agent/dev/contribute/) for more information.
+
