- Ensemble Sankey view
- CCT views to explore the entire CCT.
- Comparing two datasets pair-wise
- Histograms, Scatterplots, and Boxplots for data analysis
- Module hierarchy view for exploring the module-level supergraph.
- Exposes 2 visualization interfaces, one for single call graph, and an ensemble of call graphs along with a landing page for displaying basic information.
- Introduces ensemble processing of multiple HPCToolkit, Caliper datasets.
- CallFlow interface that exposes operations (e.g., creating, filtering, grouping, and union Hatchet's GraphFrames), data structures for handling multiple call graphs, and modules that interface the interactions performed from the UI).
- Improved web UI for visualizing the performance data collected in the form of CallGraphs.
- Migrates from the previous D3 javascript UI framework to a Vue based framework, where each view in the visualization is an independent component.

- Landing page

- CCT view
