+Because lld doesn't support ELFv1 ABI, powerpc64 also switched to ELFv2 at the same time it switched to LLVM. This brings us to a parity with modern Linux distributions. gitref:e4399d[repository=src]

+powerpc64le (64-bit little endian port) was introduced, targeting POWER8 and newer processors. gitref:b75abe[repository=src]

+Plenty of stability fixes, which fix many kernel panics.
+
+Plenty of performance improvements - performance during bulk -a package building is at least 60% higher.
