ABI Break introduced in 19.3.4 release tag.

[johnbash]

GMMLib is creating revert for ABI break introduced in 19.3.4 release to save package maintenance cost to open source distributions. SO version name will be updated back to libigdgmm.so.11 in future release. Please discard libigdgmm.so.12, no support will continue in future for same.

All existing functionality in libigdgmm.so.11 will be maintained as is.

Note, ABI revert broke API that NEO relied on. See intel/compute-runtime#244 for a fix.
