PathcoreFlow™ Release Notes

v3.3 (2023-10-04)

New Features

GLP Compliance

In this release, the application now captures audit trails about changes made in the Repository and Viewer to enable GLP compliance. Updates include an optimized CSV export feature alongside a new "Policies" framework that allows for controlled reason for change tracking.

Activity Logging

All changes made in the Repository and Viewer are now automatically tracked in an Activity Log, which may be exported as a CSV file. The Activity Log displays a list of all items that have been created, modified, or deleted, as well as information about when and by whom the changes were made.

Working in tandem with reason for change tracking, Activity Logs are also dynamic in that they compare the existing value with the value after the change was made. This new functionality is one of the many ways we've aimed toward a more comprehensive view of the audit trail.

Reason for Change Tracking

As soon as an item in the Repository or Viewer has been changed, a UI prompt will appear to allow users to input a reason for the change. This prompt may be controlled in Settings so that it only appears for specific folders or data types as to minimize impact on workflow efficiency.

Team administrators will have access to a new tab in Settings called Policies, which provides the ability to fine-tune when and where reason for change tracking is required for the team. This feature was designed to allow both GLP and non-GLP studies to be run within the same team without disrupting the existing folder structure.

For more details on how to manage policies, see the Policies section of the PathcoreFlow User Manual.

Improvements

A number of enhancements have been made to improve the usability of the software based on customer suggestions and feedback.

Viewer Improvements

  • Multi-spectral QPTIFF images which include biomarker metadata for individual channels now show that information in the Image Settings dialog

Other Improvements

  • Our Help Center has been enhanced by the addition of a Frequently Asked Questions page
  • This release includes many improvements to overall stability and security

Fixed in this Release

In this release, we have implemented the following bug fixes and UI improvements to address customer suggestions and feedback.

Viewer Fixes

  • Viewer URLS now properly support negative numbers for the position parameters
  • Fixed a bug where the heatmap was not updated for all sub-images of an image if it has multiple sub-images

Repository Fixes

  • Fixed a bug where deleting a folder with many items would cause it to rapidly disappear and reappear in the folder listing
  • Fixed a bug where an image with a large difference between width and height could fail to load a thumbnail
  • Now users are able to rename a folder to a name with a single character, instead of requiring a minimum of 2 characters

API Fixes

  • Retrieving a signature for a user without one set now correctly returns a 404 status code instead of a 500 error

Other Fixes

  • Attempting to change a Team name to something longer than 256 characters now displays an appropriate error message
  • Fixed a bug where any small annotations (which have too few points to calculate area or perimeter) would cause CSV export to fail

Notes for On-Premise Customers

  • The base nginx-template.conf has changed with this release. If you have customized this configuration file in your deployment, you are highly encouraged to incorporate the changes.
