Versioning method

IBM® Safer Payments uses a release number scheme that is based on the PA-DSS guidelines for versioning.

Versioning

Version numbers consist of four numbers that are separated by periods, for example, 6.5.0.00. Each position in the version number has a meaning:

  • The first number denotes the project generation.
  • The second number denotes feature releases or High Impact changes per PA-DSS.
  • The third number denotes Low Impact changes per PA-DSS.
  • The fourth number denotes No Impact changes. It can be one or two digits, which can also be denoted with a wildcard (“x”), for example, 6.5.0.x.

Changes in the fourth number denote changes that are not PCI relevant and therefore have no impact per the PA-DSS Program Guide.
