Release Notes

v3.2.0.1​

Build date: Sep 29, 2026

Fixed

  • Fixed local CV server discovery for projects that use project.v1.json.
  • Fixed CV Type Into occasionally losing the first character after ClickBeforeType, particularly through Remote Desktop sessions.
  • Preserved uppercase and lowercase characters when using CV Type Into.
  • Changed EmptyField clearing to use End, Left Shift + Home, and Delete, with input-settling delays for Remote Desktop targets.
  • Updated the designer so enabling EmptyField automatically enables ClickBeforeType. Runtime execution also enforces the click requirement for older or manually edited workflows.

  • Updated RestSharp and related dependencies as part of the activity-package vulnerability remediation work.

v3.1.0.4​

Build date: Jan 06, 2026

Changed

  • Migrated the Computer Vision project to the SDK-style project format.

  • Simplified project and package references and centralized assembly metadata.
  • Ensured the correct x86 and x64 OpenCvSharp native libraries are copied to build output.
  • Updated JSON dependencies and binding behavior for the newer runtime.

Fixed

  • Removed conflicting Japanese resource files that could prevent the package from loading correctly in Studio.
  • Removed obsolete application configuration from the activity project and cleaned up redundant dependencies.

v1.1.0.5​

  • Fixed coordinate handling when a reusable input region is used.
  • Fixed bitmap lifetime handling that could cause OutOfMemoryException during repeated captures.

v1.1.0.3​

Fixed

  • Fixed activities failing to retrieve the scope image from the CV cache.
  • Fixed null-reference errors when resolving activity timeouts.
  • Fixed exceptions when starting Indicate on Screen or editing a selector.
  • Improved failure messages when the CV cache is unavailable.

v1.1.0.1​
