Version 18.7

March 25, 2019

New General Features

Added the Clear Contents command. This command works only in the CSV cell selection mode, and it clears the contents of selected cells. The new version assigns the DELETE key to the Clear Contents command by default, and the Delete command now deletes both contents and delimiters.

Improved the speed especially when the opened document contains very long lines.

Improved the speed of the Sort and Delete Duplicate Lines commands using multi-threaded code.

Improved the speed of opening very large files, filter, and replace all using the AVX-2 instruction set found in recent CPUs.
