CIPRES now offers two new ASTRAL codes from the new ASTER package developed by Chao Zhang and Siavash Mirarab.
The code developers recommend that all ASTRAL users switch to the new codes: ASTRAL-Hybrid or ASTRAL-PRO.

ASTRAL-Hybrid is an upgraded, faster version of ASTRAL. It takes into account gene tree branch lengths and branch supports, making ASTRAL-Hybrid more accurate than ASTRAL.

ASTRAL-PRO is a special-purpose version of ASTRAL for PaRalogs & Orthologs. This is suitable for species tree inference from multi-copy gene family trees
