 This changelog follows the same style that I have seen LiveView, Phoenix, and Elixir use in the past. I'll try to make sure that I maintain it - probably should create some sort of automated process for it... who knows. For now - there's only one release so this should be good enough!
 
+## 1.1.0
+
+### Enhancements
+
+- Add `:release_dir` configuration option to customize the deployment directory for Elixir releases. This allows matching the directory path expected by your release bundle. Defaults to `/srv/<app>/release` for backward compatibility.
+
+- Add ARM architecture support for AWS CLI installation in the bootstrap script. The startup script now automatically detects the instance architecture (x86_64 or aarch64/arm64) and downloads the appropriate AWS CLI version, enabling support for Graviton-based EC2 instances.
+
 ## 1.0.0
 
 This is the first official release! So everything is empty. Read the docs to get started - have fun!
