in thread obfuscating source code
An end user could almost always use an older version and still be fine. Processors rarely make changes that cause older api's to not work. More frequently the transactions processed using an older api do not qualify for the best rates. When an upgrade is required, the merchant's bank will usually tell the merchant they have to be using the most recent version, or they can't process transactions.
