Framework Documentation - Filter 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.x)	v3 (3.0.0)
PHP	^7.2.5	^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

InputFilter and OutputFilter have the same signatures in 3.0.0 as in 2.0.0. The protected
InputFilter::decode() deprecated earlier is still present; it was removed in 4.0.0 — see
Updating from v3 to v4.

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.x)	v3 (3.0.0)
php	^7.2.5	^8.1.0
joomla/string	^1.3 | ^2.0	^3.0

joomla/language remains optional, in suggest, for OutputFilter::stringUrlSafe() with
language-specific transliteration.
