python-biopython (1.80+dfsg-1~0exp0) experimental; urgency=medium Starting with biopython 1.79, command wrappers are being deprecated, and may be removed past biopython 1.81. This has the notable implication that support of the muscle command past version 5 has never been implemented, and probably will never be[1,2]. Users of muscle are invited either to use a generic command launcher such as the module "subprocess", or to stick to muscle 3.
