Wikibase DataModel release notes

Version 10.0.0 (TBD)

• Removed support for calling Statement::addNewReference() and StatementList constructor with a single array argument, which was deprecated in Version 9.6.0 (2021-03-31). These should now be called with a variadic argument list.
• Added __serialize() and __unserialize() methods to the EntityId interface, and removed the serialize() and unserialize() methods and the Serializable interface.
• Added native type hints to the Statement and StatementList classes
• Added strict_types=1 to Statement.php, StatementList.php, and related test files
• Removed support for repository names in entity IDs (e.g. foo:Q1234)

Version 9.6.1 (2021-04-01)

• Snak now declares getHash() and equals() methods again, which it used to inherit from the Hashable and Immutable interfaces prior to version 9.6.0. (The methods were never removed from any specific classes, but since Snak is an interface, Phan started complaining that the methods were unknown.)

Version 9.6.0 (2021-03-31)

• ReferenceList::addNewReference(), Statement::addNewReference() and the StatementList constructor supported being called with a variadic argument list, with a single array argument, or (in the case of StatementList) with a single Traversable argument. The latter two forms are now deprecated (though they still work); please update your code: for instance, change ->addNewReference( [ $x, $y ] ) to ->addNewReference( $x, $y ), and ->addNewReference( $snaks ) to ->addNewReference( ...$snaks ).
• Statement, Reference, SnakList and Snak no longer implement the Hashable and Immutable interfaces from DataValues/DataValues.
• Removed usages of the Comparable interface
• Made the library installable together with DataValues 3.x
