New Features
Concept Sets: multiple concept sets can be opened at the same time; you can now specify how to add the concept (as exclude, as descendant); created reusable components such that all concept set editing (cohorts, characterization, incidence rate, repository concept sets) share the same codebase.
Cohort Pathways: a 'tabular results' view was included in the results, with the ability to download the raw data as CSV. The tables also include other summary results, such as distinct pathways by rank.
Characterizations: in addition to being able to define prevalence statistics with custom criteria, you can now define distribution statistics based on custom criteria, looking at values like duration, number of records, and other domain-specific values.
Cohort Samples: once a cohort definition is generated, you can create a sample of patients by specifying simple demographic criteria and sample size, and the sample set will be created for easy navigation to the patient profile. You can find this under the new 'Samples' tab in cohort definitions.
Cohort Definitions: Support for new 'condition status' concept in criteria; print friendly is now generated server-side from markdown; new options for counting events in window criteria: distinct start date and distinct visit (in addition to the current distinct domain concept).
Test Coverage: We've worked to improve our test coverage in WebAPI and in the dependent libraries since 2.7, and we plan on making more progress in post 2.8 releases.
