TCRD v5.4.0
===================
This README describes changes from v5.2.0.

DrugCentral Update
==================
- DrugCentral data updated TDLs regenerated.
- Added column drug_activity.dcid for DrugCentral drug IDs, so Pharos can
easily link to DrugCentral.


GuideToPharmacology
===================
- Table chembl_activity renamed to cmpd_activity and refactored to store
activities of different types (ie. from different sources):
