The Open Targets Platform integrates evidence from genetics, genomics, 
transcriptomics, drugs, animal models and scientific literature to score and 
rank target-disease associations for drug target identification. The 
associations are displayed in an intuitive user interface 
(https://www.targetvalidation.org), and are available through a REST-API 
(https://api.opentargets.io/v3/platform/docs/swagger-ui) and a bulk download 
(https://www.targetvalidation.org/downloads/data). In addition to target-disease 
associations, we also aggregate and display data at the target and disease 
levels to aid target prioritisation. Since our first publication two years ago, 
we have made eight releases, added new data sources for target-disease 
associations, started including causal genetic variants from non genome-wide 
targeted arrays, added new target and disease annotations, launched new 
visualisations and improved existing ones and released a new web tool for batch 
search of up to 200 targets. We have a new URL for the Open Targets Platform 
REST-API, new REST endpoints and also removed the need for authorisation for API 
fair use. Here, we present the latest developments of the Open Targets Platform, 
expanding the evidence and target-disease associations with new and improved 
data sources, refining data quality, enhancing website usability, and increasing 
our user base with our training workshops, user support, social media and 
bioinformatics forum engagement.
