MOSES| Structural Post Processing

Hello,

I am referring to Moses Reference Manual Rev 11.03.00

For JOINT POST -CODE " {CODE option he need not be re-issued. EDITION defines the edition of RP2A which will be used checked for the check. If it is OLD, then the first supplement of the 21st edition will be used otherwise the "new" method will be used.".

My question, the new method in the above statement is referring to the API 22nd Edition ?
