Compiler edit 920: the minimum run version stored in the program header—see compiler edit 896 in 6.5.1657.0—now distinguishes between two variations of the .CLEAR statement:
.CLEAR $MAP() ! (collections) minimum version is 1354
.CLEAR MAP() ! (mapped or DIMX array) minimum version is 1624
Previously it was setting the minimum version in both cases to 1624. The point is largely moot since the minimum version for running any program containing the new header type is 1657, but it was creating confusion as to whether such a program could be run if the header was removed (using the /F1 switch).
