Changes are initiated by suggestions from the A-SPEC Community and through research undertaken by GISSA.

No changes are introduced into the A-SPEC Specifications without full consultation with the A-SPEC Community. A-SPEC Community members will be contacted directly for comment on relevant proposed changes.
