Version 1.7.7 still reports as 1.7.6 & the SIONlib 32-bit Endianness identification flag is 0

Morning, could someone try generating a 1.7.7 SIONlib file please and have a look at the binary header. It looks like version 1.7.7: 1.) Does not set the endianness identification bytes. 2.) Still has the version set as 1.7.6.

I kind of need those 4 bytes to reliably figure out if the program is little, big or mixed endian. When I do module load SIONlib/1.7.7 I get this incorrect behavior in produced files.
