1.1.9 (2026-06-17)
- Completed the remaining three phases of the TypeScript migration (strict null checks,
noImplicitThis, andnoImplicitAny) via assisted codemods, so the entiresrc/tree now type-checks clean under full strict mode. Only optional tightening of leftover loose types remains. - Fixed search not highlighting words that were split by line-break points in the text (e.g. inside long URLs).
- Fixed hilight neXT badges not showing due to issue with rollup.js.
4chan-neXT uses its own userscript namespace.
To migrate settings:
- Export settings from your current script.

- Import your settings into 4chan-neXT.
