Report requests using the Standard.Prompt.xslt will now default to a user's email address rather than their username. This allows user with non-email address to avoid re-typing their email address when requesting report runs. The prompt will also allow replacement of the user as the default recipient of the email (it was formerly read-only). Lastly, new Reports will automatically have their PromptXslt set to Standard.Prompt.xslt, so they 'play nicely' with the Report Request UI. This setting can be overridden in Design > Configuration > Modules > Report > Settings, from the PromptXsltDefault setting.
