Version 18.8

April 23, 2019

New General Features

Greatly improved the speed of opening very large files, Find/Replace/Filter, the Uppercase, Lowercase, Capitalize, Full-width, and Half-width commands using multi-threaded code and the AVX-2 instruction set found in recent CPUs.

Greatly improved the speed especially when the opened document contains very long lines.

The new version allows you to press CTRL + SHIFT + V several times consecutively in all text boxes in dialog boxes to paste previously copied text in the Clipboard history of the editor.

Updated the IPTip.jsee macro to support new GeoLite2 CSV format. This macro is used to show the country name as a tooltip when the mouse hovers on IP v4 addresses if IP v4 active strings are enabled.

Changed the default keyboard shortcuts. SHIFT + TAB is assigned as the Decrease Line Indent command, and CTRL + SHFT + T is assigned as the Most Recently Closed File command.
