on GitHub

DVR-Scan 1.6 greatly improves masking capabilities with the new region editor (user guide):

Multiple regions can now be defined with any shape, size, and complexity. Region data can be saved to a file and loaded again. Regions can also be specified by command line.

There are also several other bugfixes and improvements, such as improved seeking performance.
