v4.0.9

Do you read these release notes? We're considering making changes to them and want to hear from you before we do that. See this issue for details and to give your input.

Notable changes

• api.MessageEvent.origin.USVString_type was removed, since it recorded data about browser internals that are not observable to web developers. (#13136)

• api.IDBIndex.name.renaming_with_name_setter was renamed to api.IDBIndex.name.renaming_through_name_setter to reflect the convention set by api.IDBObjectStore.name.renaming_through_name_setter. (#13216)

• css.properties.break-inside.multicol_context.column and css.properties.break-inside.paged_context.page were renamed to css.properties.break-inside.multicol_context.avoid-column and css.properties.break-inside.paged_context.avoid-page to reflect the actual names of the values they describe. (#11924)

• api.Response.Response.body_param_null was renamed to api.Response.Response.body_parameter_optional to follow the guideline on parameter feature names.

• The following non-existent, long-removed, or otherwise irrelevant features have been removed:

  • api.EventTarget.removeEventListener.type_listener_parameters_optional (#13143)
  • api.HTMLImageElement.error_event (#13006)
  • api.MutationObserverInit (#12795)

Known issues

• In v3.3.9, the structure of features for css.properties.place-content, place-items, and place-self changed (#11214). This is an incomplete fix to the problem of undocumented namespaces appearing in places where you might otherwise expect compatability data. The restructuring of the data is a work in progress and may change again in a future release. See #6175 for more information.
