 ## [UNRELEASED]
+
+* Add new `ncbi_tranlation_table` of the 15th genetic code (i.e `blepharisma_macronuclear_genetic_code`)
+
 * Relax requirement of `decode`, such that it no longer needs to check for
   invalid data. Note that this change is not breaking, since it is not possible
   for correctly-implemented `Alphabet` and `BioSequence` to store invalid data.
