-## Unreleased
-### Added
-- Output now contains a reminder to use `fif --fix`
-### Changed
-- Some extensions are considered to be always valid - these are:
-  - "filepart", "part", "crdownload": Partially downloaded files, renaming could break download
-  - "bak", "backup": Backup copies are a common idiom (e.g. "game.exe.bak") and should be respected
-### Fixed
-- Support for many file types that are subcategories of others (e.g., fif will no longer rename apk files to zip) (#1)
-
 ## v0.5.1 - 2022-04-12
 ### Added
 - When using the [`infer`] backend, fif is now able to detect [Mach-O](https://en.wikipedia.org/wiki/Mach-O) binaries
