- Remove CefRequestContextHandler::OnBeforePluginLoad and CefRequestContext::PurgePluginListCache (fixes issue #3047). These methods stopped being relevant after the removal of Flash support in January 2021. The last remaining PPAPI plugin (PDF viewer) will switch to a non-plugin implementation in the near future (see https://crbug.com/702993#c58) and functionality related to plugin filtering has already been removed in https://crrev.com/343ae351c9.
