-The latest version of 3D UTAPWeLS, version 4.28, was released on May 17^th 2018.

• *Fast Sonic Logging
•     -The fast sonic logging simulator works with vertical wells and horizontal layers.
• *Sonic Studio
•     -The module has received a general update making plots faster, and easier to navigate.
•     -Calculation and plot of first arrivals has been reinstated.
•     -Advanced settings, for wave form simulators are now available for use.
• *Updated rock components properties according to "Advanced Interpretation of Wireline Logs (SLB)"
•     -Density, Th (ppm), Ur (ppm), and K (%) properties have been updated.
• *Various Smaller Bugs and Features

•     -The display unit system is consistent across project (not just the well).
