Changes in Thunderbird 96

cloudFile API

  • added templateInfo as a supported return value property of the onFileUpload event, to specify a CloudFileTemplateInfo with additional information for the cloud file entry added to the users message

  • added error as a supported return value property of the onFileUpload event, to show an error message to the user, in case upload failed

  • added onFileRename event to properly handle cloud file rename operations (the file on the server should be renamed as well, if the cloud file attachment in the email is renamed by the user)

messages API

  • added attachment as a supported property of the query(queryInfo) function, to be able to query for messages with or without attachments
