SnapGene Version 8.2.0

SnapGene 8.2.0 was released on September 24, 2025.

Overview

SnapGene 8.2 streamlines access to metadata and contextual information with a new file table for multiple file selections, enhanced tooltips and modernized trace view and info panel.

File info table for multiple selections

The new file info table provides an overview of key file metadata for your selection.  Customizable columns allow you to tailor and sort the view to your needs.

Enhanced tooltips

Quickly understand key information about your sequences, with modern, visual tooltips for enzymes, features, primers, and more.

Streamlined, modern UI

Trace view has been updated to be fully integrated into the main SnapGene UI with a new mode to view full height.  The redesigned flyover control for the folder panel improves access to key controls.  The modernized info panel displays metadata and embedded files clearly.
