As stated in the Adobe Support Lifecycle Policy, Adobe provides five years of product support from the general availability date of Adobe Reader and Adobe Acrobat (Windows and Macintosh – Note: Adobe only supports the most recent major version of Adobe Reader for Linux Version 9.x). In line with that policy, support for Adobe Reader 8.x and Adobe Acrobat 8.x will end on November 3, 2011.
End of Support
End of Support means that Adobe will no longer provide technical support or distribute runtimes, including product and/or security updates, for all derivatives of a product or product version (e.g. localized versions, minor upgrades, operating systems, dot and double-dot releases, and connector products).
Recommendation to Customers/Users
Adobe strongly recommends that customers update to the latest versions of Adobe Reader at: http://get.adobe.com/reader. By updating installations to the latest versions, customers benefit from the latest functional enhancements and improved security measures.
