+- Removed `Package::get_file_checksums` and `Package::get_file_ima_signatures` functions, the same information is now retrievable using `Package::get_file_entries`.

 ### Added
 
 - Support for symbolic link in file mode.
-- Make file type const `REGULAR_FILE_TYPE` `DIR_FILE_TYPE` `SYMBOLIC_LINK_FILE_TYPE` public, because `FileMode::file_type` is public, sometimes we need this const to determin file type.
