# Changelog

The following changes have been made to classes/functions/methods of this extension.

Version | Function | Description
--- | --- | ---
5.5.0 | pack | The "Z" code was added with equivalent functionality to "a" for Perl compatibility.
| unpack | Changes were made to bring this function into line with Perl: The "a" code now retains trailing NULL bytes.
