Periodically, Adobe updates Flash Player with new features or fixes to minor problems. The Automatic Notification and Update feature allows Adobe to automatically notify you when an updated version of Flash Player is available so that you can install it right away.
Updates to Flash Player help ensure that Flash Player works properly and may contain important security changes. Adobe recommends that you update to the latest version of Flash Player whenever a new version is available, especially when a security update is mentioned. Although you may choose whether to receive automatic notification of updates and how frequently to receive them, Adobe is not responsible for errors or security problems that occur because the version of Flash Player on your computer is not the most current one available. To specify notification settings, use the Global Notification Settings panel.
