Since Hifiasm-0.18.1 (r467) beta:

1. Fixed bugs for the UL-integration assembly that may lead to unbalanced two haplotypes, especially for the Hi-C phased assemblies and the dual assemblies.
2. Fixed bugs for the UL-integration assembly that may output incorrect rd:i in the gfa files.
3. Improve the phasing results for the Hi-C+UL+HiFi assembly.
4. The bin files of Hifiasm-0.18.1 (r466) could be reused.

Please note that this mode is not stable. There are several known issues to be fixed:

1. The UL + HiC + HiFi might introduce higher numbers of hamming errors.
2. Only well-tested with >=100kb UL reads.
3. The QV could be further improved.
