Pass thru the export for React's useContext hook.
Fixed bug with use of key prop with components created using fromClass.
Changed rendering of children to replace undefined children with null
children, because React.Fragment apparently does not like undefined
children.
Only Kefir properties, in other words, objects that inherit Kefir.Property,
are lifted. Kefir.Stream and Kefir.Observable objects are not lifted and
will result in errors.
Dropped previously obsoleted fromKefir combinator.
$$ref is no longer required due to using React.forwardRef in fromClass.
Added support for fragments, IOW the React.Fragment component, and deprecated
fromKefir, because fragments make it unnecessary:
-const Foo = ( ... ) =>
- fromKefir( ... )
+const Foo = ( ... ) =>
+ <React.Fragment>
+ { ... }
+ </React.Fragment>Kefir was changed from a dependency to a peer dependency to avoid the possibility of having multiple versions of Kefir in a project.
