Release notes

v1.4.9

June 5, 2026

CytoCanvas™ 1.4.9 introduces the following features and improvements.

Spatial data visualization: CytoCanvas now supports the Cells2Stats spatial data output format, enabling visualization of spatially-resolved transcript locations and cell and nuclear boundaries at the full flow cell scale. This is fully backwards compatible with Cells2Stats 1.3.x visualization output.
Workspaces: CytoCanvas automatically creates and maintains a workspace alongside each dataset. Workspaces preserve your session state — including the loaded data source and view settings — so you can close and reopen the application without losing your place.
Credential profiles: AWS credentials are now managed as named profiles in the application. Profiles are created once and reused across sessions, replacing the need to enter credentials each time you load data from Amazon S3. Credentials are no longer tied to individual workspaces.

Montage view: The Montage view has been removed.
Cell Table: The Cell Table has been removed.
Cell groups and lasso select: Cell group creation, lasso select, and related cell grouping tools have been removed.
