### Breaking changes

`CompletionResult.span` has been renamed to `validFor`, and may now hold a function as well as a regular expression.

### Bug fixes

Remove code that dropped any options beyond the 300th one when matching and sorting option lists.

Completion will now apply to all cursors when there are multiple cursors.

### New features

`CompletionResult.update` can now be used to implement quick autocompletion updates in a synchronous way.

The @codemirror/closebrackets package was merged into this one.
