+
+### Additions
+
+ - Add the [IggyTop receptor reference database](https://iggytop.readthedocs.io/en/latest/index.html),
+   a metadatabase including receptor data from IEDB, VDJdb and others ([#652](https://github.com/scverse/scirpy/pull/652)). IggyTop includes additional data curation steps (e.g. low quality sequences from 10x dataset filtered out,
+   amino acid sequences are now consistently `junction_aa` sequences). It updated bimonthly, pre-built and can
+   be downloaded from GitHub. This is much faster and more reliable than the previous approach of downloading and building AnnData objects from reference database on-the-fly. The previously existing functions `datasets.iedb` and `datasets.vdjdb` are now wrappers around `datasets.iggytop`.
