0.18.0 (2026-06-27)

Upgrade notes

0.18.0 keeps the public API compatible, so it stays a minor release. Two runtime behaviors changed in ways an existing app can notice.

Text widgets now drive the real terminal cursor. Input and TextArea place the terminal's own cursor at the editing position and no longer draw the ▌ glyph, so the cursor blinks and behaves natively. To keep the drawn glyph, add WithInputVirtualCursor() or WithTextAreaVirtualCursor(); to take over cursor placement, build the app with WithManualCursor(). WithInputCursor and WithTextAreaCursor are now deprecated aliases for WithInputCursorRune and WithTextAreaCursorRune, which set the glyph used in virtual-cursor mode.

Text is now measured with an in-house grapheme engine. Width, wrapping, and cursor math run through go-tui's own grapheme-cluster code, so emoji, combining marks, and other wide or multi-rune clusters can measure or wrap a cell differently than in 0.17.0. If your tests assert exact column counts or wrap points, re-baseline them against 0.18.0.
