What happened to composition function of BioSequences?

I am trying to implement an older package that uses BioSequences, especially the composition function. This function is however gone from the newest BioSequences, so e everything breaks.

Has composition been replaced by something else?

Thanks

Makes sense, thank you.

I found a work around.
