The completely rewritten web client represents a major step forward for i2b2 that features an improved layout, greater visual customization,  and a new plugin architecture. The new web client version eliminates usage of YUI and uses the latest versions of jQuery, Bootstrap 5 and Golden-Layout libraries, which will ensure maintainability far into the future.

The core i2b2 platform now supports the OMOP data model, which is queryable through the comprehensive ENACT-OMOP Ontology. (MSSQL and Oracle are supported. Postgres support will be added in 1.8.1.)
