Drag and drop of text is now supported in the text area; it can be disabled in the Mouse pane of the Utilities>Global Options dialog box.
The Edit>Complete Word command (shortcut: Control-B) now looks in all visible buffers for completions.
Edit>More Clipboard>Vertical Paste command (shortcut: Control-E Control-P) behaves in a more intelligent manner. Entering characters while a rectangular selection is active inserts into each row of the selection, thus a zero-width rectangular selection can now act like a “tall caret”.
The new Edit>More Selection>Rectangular Selection command (shortcut: Alt-\) permits rectangular selections to be created using the keyboard. A static bar indicator is shown when rectangular selection mode is active. Clicking beyond the end of a line in rectangular selection mode (or Control-clicking otherwise) inserts the appropriate amount of whitespace and moves the caret to the clicked location.
The new Edit>More Clipboard>Paste Deleted command (shortcut: Control-E Control-Y) lists the 20 most recently deleted strings of text. This list of deleted strings is also persistent.
Register contents are now saved between editing sessions.
The limit of 8 text areas editing a single buffer has been removed.
Fold start lines are now colored according to their nesting level in the text area. The colors can be customized in the Syntax Highlighting pane of the Utilities>Global Options dialog box. Alt-clicking on a fold in the gutter (or clicking with the middle mouse button) now narrows to that fold.
When soft wrap is on, the text area now scrolls by screen lines, instead of scrolling by physical lines.
