求翻译：If you don't upgrade now, we recommend that you upgrade soon. Your current version of Yahoo! Mail is no longer available. You may use Yahoo! Mail Classic instead, but we strongly encourage you to either upgrade to the newest version of Yahoo! Mail or review Yahoo! Mail Help for other options. Go to Yahoo! Mail Classic now.是什么意思？
