Adobe annonces that the support for Adobe Acrobat X and Adobe Reader X will end on November 15th, 2015. After that Adobe will no longer provide technical support and there will also be no bug fixes and security updates anymore.
IMHO that’s not a big issue since Acrobat X is a version to forget anyway. Beside a new (but not better) user interface there are no new features for print production in AX – just new bugs. Most users stayed with Acrobat 9 or upgraded to Acrobat XI.
