Framework Documentation - Authentication Package

Updating from v2 to v3

Release 3.0.0 raises the PHP requirement and reformats the codebase. No public or protected
method signature changed, so code written against 2.x keeps working on PHP 8.1.

At a glance

	v2 (2.0.1)	v3 (3.0.0)
PHP	^7.2.5 | ^8.0	^8.1.0
Public API	—	unchanged
Coding style	Joomla Coding Standard	PSR-12

Minimum supported PHP version raised

All Framework packages now require PHP 8.1 or newer.

No API changes

Authentication, AbstractUsernamePasswordAuthenticationStrategy, both strategies, all three
password handlers and both interfaces have the same signatures in 3.0.0 as in 2.0.0.

Codebase converted to PSR-12

The package was reformatted from the Joomla Coding Standard to PSR-12. This touches nearly every
line and changes no behaviour.

Dependency changes

Package	v2 (2.0.1)	v3 (3.0.0)
php	^7.2.5 | ^8.0	^8.1.0

The package has no required runtime dependencies. joomla/database and joomla/input remain in
suggest for Strategies\DatabaseStrategy and Strategies\LocalStrategy, and moved to ^3.0.
