 This is a minor release of TeleSculptor that provides both new functionality
 and fixes over the previous v1.1.0 release.
 
-Updates since v1.1.0
+The biggest changes in this release are the transition to a new Sphinx-based
+user manual at https://telesculptor.readthedocs.io, the removal of deprecated
+MAP-Tk command line tools, improved handling of mesh coloring from the video,
+and an interface for manual camera calibration by manually placing camera
+registration points on frames.
+
+TeleSculptor v1.2.0 also builds on updated KWIVER v1.6.0 and Fletch v1.5.0,
+which provide upgraded third-party packages and improvements to algorithms.
+For example, TeleSculptor now uses VTK 9.0, OpenCV 4.5, and Qt 5.12.
+While command line tools have been removed from TeleSculptor, it is now
+possible to reproduce the entire TeleSculptor processing chain from the
+command line using the *kwiver* command.  The command line workflow uses
+KWIVER v1.6 directly and does not require the TeleSculptor GUI.
+
+Additional details about TeleSculptor changes in this release are provided
+in the detailed release notes below.
