 * `[/info/biotypes/name/:name/:object_type]` endpoint to retrieve the properties of biotypes with provided name (and object_type)
 
 ## Updated endpoints
-* `[/vep/:species/*]` updated the frequency keys in the collocated variants entry from *_maf to *_af. The new naming better reflects that we only report allele frequencies from co-located variants if the input allele is matched
+* `[/vep/:species/*]` Created a frequency entry in the colocated variants entry and removed all *_maf and *_allele entries which previously reported allele frequencies. Allele frequencies are now stored in the frequency entry for a colocated variant. Allele frequencies are now reported for each alternative allele of the input variant. Allele frequencies if available are reported for the followong populations: 1000 Genomes Project: afr, amr, asn, eas, eur, sas; ESP: aa, ea; gnomAD: gnomad_afr, gnomad_amr, gnomad_asj, gnomad_eas, gnomad_fin, gnomad_nfe, gnomad_oth, gnomad_sas
 * `[/variation]` added genotyping_chips option to the variation endpoint
 * `[/family]` the output of the family endpoint changed
