# Dendrogram changelog

## v.next

* Moved the Dendrogram Playwright E2E suite into the package (playwright/); helpers from @datagrok-libraries/test/src/playwright

## 1.4.15 (2026-06-23)

* Assign Clusters: optionally add per-cluster medoid columns — `Medoid Rank` (1 = most representative, enabling Top-N extraction) and `Avg Distance to Cluster` (each member's mean distance to the other cluster members). Computed per cluster without materializing the full distance matrix.

## 1.4.14 (2026-05-19)

* GROK-20143 Demo: Heatmap: cells are editable due to incorrect demo setup

## 1.4.13 (2026-05-19)

* GROK-20140: Dendrogram: errors on switching beetween chem space and molecule activity cliffs demos

## 1.4.12 (2026-05-14)

* Hierarchical Clustering: Fixed errors when the table view is closed during compute (e.g. quickly switching demos) — bail out before injecting the tree and avoid double-closing the loader neighbor

## 1.4.8 (2026-02-03)

* Horizontal zooming of dendrogram with mouse wheel and pinch gesture.

## 1.4.7 (2026-02-02)

* Resizable dendrogram neighbor panel in the grid.
* Cluster assignment based on cut-off slider or clusters number.
* Fix error handling in hierarchical clustering.
* Cut slider indicator vertical line
* Closing old dendrogram neighbor on new clustering

## 1.4.5 (2025-08-01)

* Support initialization

## 1.4.1 (2025-06-16)

* Fix loading with empty table, add default options for molecules and sequences

## 1.2.33 (2024-09-02)

Fix for dependency math lib version update

## 1.2.32 (2024-08-23)

### Bug fixes

* GROK-15949:Fix open GridWithTree: error
* Fix error on second Hierarchical Clustering
* Fix error on mouse hover and current row changed

## 1.2.31 (2024-08-19)

Fix Hierarchical clustering namings.

## 1.2.28 (2024-03-30)

### Features

* #2707: Add original and canonical to monomer

## 1.2.27 (2024-03-07)

### Bug fixes

* Bump dependencies version, NEWICK_EMPTY

## 1.2.26 (2024-03-06)

### Bug fixes

* Bump dependencies version
* Fix tree traverse order, fix tests

## 1.2.18 (2023-07-21)

This release focuses on improving analysis stability and usability.

* Dependency: datagarok-api >= 1.15.0*

### Features

* Implemented the ability to select all leaves from a certain node.
* Added a separate loader view to the dendrogram.

* Moved hierarchical clustering script to the client side.
* Allowed to switch distance calculation method for macromolecules (Hamming or Levenstein) in case of MSA.
* Enabled Dendrogram to work with semType `macromolecules`.
