v2.0.017 Apr 2026Release notes
Open source →Features
This release is a code cleanup maintenance release. The only rather internal feature is increased performance
when using opcache, by generating and using static alias mapsBreaking changes
The possibility to allow case insensitive class loading has been removed without substitution.
This feature required optimized class loading to be turned on and rewrote the class map that
composer generated. Up to date packages, that rely on PSR autoloading require case sensitive
class names anyway.PHP support for very old PHP versions are dropped.
Older versions of alias loader
v1.2.2 was released prior to
2.0 which received some minor bugfixes. If you need support for older PHP versions or
case insensitive class loading this version is for you and will continue to work. -
