As far as i know you can download the (older) versions and compare the files.
But thats not needed.
Just go back to original juns loader or use, as i did, IG-88 v0.11
Here is the confirmation of IG-88 that using juns original extra is absolute fine:
I used the 3615 v0.11 extra from his post:
"extra.lzma for loader 1.03b ds3615 DSM 6.2.3 v0.11_test, same added drivers as for 6.2.2 like newer intel drivers, 10G nics, ..."
Dont forget to copy the newest rd.gz and zImage from 25426
