Release/Version Information:

VA decisions for specific versions may include a ‘.x’ wildcard, which denotes a decision that pertains to a range of multiple versions.

For example, a technology approved with a decision for 7.x would cover any version of 7.(Anything) - 7.(Anything). However, a 7.4.x decision would cover any version of 7.4.(Anything), but would not cover any version of 7.5.x or 7.6.x on the TRM.

VA decisions for specific versions may include ‘+’ symbols; which denotes that the decision for the version specified also includes versions greater than what is specified but is not to exceed or affect previous decimal places.

For example, a technology approved with a decision for 12.6.4+ would cover any version that is greater than 12.6.4, but would not exceed the .6 decimal ie: 12.6.401 is ok, 12.6.5 is ok, 12.6.9 is ok, however 12.7.0 or 13.0 is not.
