	- Use Readonly module for private constants.
	- Improve legability of some regexes.
	- Improved unit tests, in particular for long and UTF-8 passwords.
	- Treat given passwords as strings of bytes instead of characters.

v1.13	2022-01-16
	- Replace use of Crypt::Eksblowfish::Bcrypt with the new Crypt::Bcrypt module.
	- Replace the dependency on version.pm >= 0.77 with a ->can() check.

v1.14	2023-01-03
	- Use algo name instead of int in password_hash() error message when Argon2 hashing is requested but required Crypt::Argon2 module is not installed.
	- Make password_needs_rehash() call password_info() as a method instead of function for better subclass support.

v2.00	2024-01-08
	- Improved documentation.
	- Moved most of the code into new 'protected' methods (all prefixed with an underscore) for easier overridding in subclasses, should there be a desire to do so.

	- Static method verify() now returns undef (previously 0) if the crypted string format is unrecognized.
