Lt Releases

We're continuously improving features and performance, fixing bugs, and releasing updated content to Lt. Here are our latest releases.

Show releases for:

July 30, 2021

Software

New Releases

  • Lt Sensor settings have been added to the Settings library for authors to use when creating their own lessons, also to configure the Data Sampling panel

Improvements

  • Update hardware reset workflow to make sense for SpectroVis
  • The Edit lesson button in the module card now navigates you directly to the lesson card

Technical

  • KCDA 1.9.1 with support for Lt Sensors. This includes some minor improvements to Vernier device support
  • Lt now supports sampling with Lt Sensors. Sampling with Lt Sensors requires KCDA 1.9.1 or higher. If you have KCDA installed, it will update automatically, unless automatic updates have been turned off. KCDA 1.9.1 is a recommended update, but for sites updating manually, Lt will continue to work with KCDA 1.8.1 until it is convenient to update
