# Changelog
## 3.0.0
[New] A new hashing class has been added `Crc32MetaDataHash`. It let you work with
large files as the hash is calculated using metadata of files: filename, size, mtime and mode.
(Thanks to @pecuchet. See PR #9).

the method `hash` receives a filename instead of the filename content.
