This is a hotfix release to fix a bug with how certain types of frameshift mutations were handled. Previously, we were not creating the correct mutant peptide sequence for these variants. See this GitHub issue for more information.
This version also includes a sanity check to error out if the wildtype amino acid in the wildtype protein sequence differs from the expected wildtype amino acid as listed in the protein change. This situation might occur if the VCF was annotated with a different reference build than the one used for alignment and variant calling.
