Note that in LC 8.0.0 DP 13 and later, the IDE save commands don't use 
"the stackFileVersion" and save as specific versions directly.  You may 
want to update your toolbar extension to take advantage of this!  For 
example, simply use:

     save stack "my stack name" with format 2.7

(This is new syntax in 8.0.0 DP 13).
