When I run composer update, I get this message:
- Root composer.json requires mediawiki/semantic-breadcrumb-links ~2.0 -> satisfiable by mediawiki/semantic-breadcrumb-links[2.0.0, 2.0.1].
- mediawiki/semantic-breadcrumb-links[2.0.0, ..., 2.0.1] require mediawiki/semantic-media-wiki ~2.5|~3.0 -> found mediawiki/semantic-media-wiki[2.5.0, ..., 2.5.8, 3.0.0, ...,3.2.3] but it conflicts with your root composer.json require (~4.0).
I see in the commits that support for SMW 4.0 was added, but I don't know why this error is given.
