 ### Code Refactoring
 
 - **relpath:** Use `$PSScriptRoot` instead of `relpath` ([#4793](https://github.com/ScoopInstaller/Scoop/issues/4793))
+- **reset_aliases:** Move core function of `reset_aliases` to `scoop` ([#4794](https://github.com/ScoopInstaller/Scoop/issues/4794))
 
 ## [v0.1.0](https://github.com/ScoopInstaller/Scoop/compare/2021-12-26...v0.1.0) - 2022-03-01
