Since Hifiasm-0.18.0 (r461) beta:

1. Fixed bugs for the UL-integration assembly that may lead to assertion failure.
2. Could produce the cleaner assembly graph with UL reads.
3. Improve the phasing results for the Hi-C+UL+HiFi assembly.
4. Slightly improve the assembly quality for the homozygous sample.
5. The bin files of Hifiasm-0.18.0 (r461) 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.
