Hello, last couple of days we've released v0.36.0 & minor follow-up v0.36.1 to ensure backwards compatibility. We caught the issue before rolling release out. Version v0.36.1 will roll out on normal train next Tuesday. Highlights in this release were - Breaking change: Requiring PHP 7.2.9+, up from 5.6.99/HHVM in alignment with recent MediaWiki core changes - Deprecating change: Rename LookupElement's onLookupMenuItemChoose to onLookupMenuChoose to follow naming scheme listeners – {Emitter}{Event}. Thanks to Bartosz Dziewoński and Ed Sanders for quickly identifying and fixing the backwards compatibility issue - Amending and updating TextInput- and DropdownWidgets paddings minimally to fully align with Design Style Guide's components templates[0]. You can find details on additional new features, code-level, styling and interaction design amendments, and all improvements since v0.35.0 in the full changelog[1]. If you have any further queries or need help dealing with breaking changes, please let me know. As always, interactive demos[2] and library documentation is available on mediawiki.org[3], there is comprehensive generated code-level documentation and interactive demos and tutorials hosted on doc.wikimedia.org[4].
