Gather View now supports switching between active volumes using the Page Down/Page Up hotkeys.

Horizons: Horizon Smoothing: Improved results near the edge of data

Min Value, Max Value, and Location information are now displayed in the Data Histogram window.

The Data Histogram window has been enhanced as follows:

• The options to export min/max values for a particular line or all data to a CSV file are now available. To do this, right-click the Line field, and select the desired option.
• The Screen Capture feature is now supported. 

The Single Well view has been enhanced with improved control over display settings as follows:

• For gather tracks, Density and Wiggle can now be selected for display. The display range can now be controlled, including estimating it from the volume.
• The control settings for the Colour bar have been improved for the seismic, gather, and connecting tracks, where colour bar size and panel background can now be customised. Multiple tracks can be selected and the settings can be updated simultaneously.

The visibility of the tabs in the control panel side menu on Insight can now be customised using one of the following methods:

• Right-click a tab and select Hide "X".

• The Preferences window (accessed from the File menu or right-click a tab > Manage tab visibility). The tabs to display can be selected and unselected from the Tabs tab.

A warning will now display in the details panel if a volume contains NaN or INF samples. The warning will also include the location of one of the NaN/INF samples for newer volumes.
