What is new in Neon Vision Editor 1.9.2

## [v1.9.2] - 2026-10-06

### Why Upgrade

- Delete the previous word with Option-Delete on macOS, including Unicode text.
- Keep mobile editor actions and AI settings accessible from the first layout.
- Optionally rank external AI chat context with explicit TypeSafe consent and conservative fallback.

### Highlights

- Adds configurable Join Lines (Command-J) and Format JSON (Command-Option-J) shortcuts on supported hardware keyboards (#713).
- Allows custom macOS toolbar actions to be reordered in the chooser, including optional preset and AI-provider controls (#715).
- Adds experimental, opt-in Jev ranking of optional context for external AI chat, with TypeSafe disclosure, Keychain storage, conservative fallback, and per-request usage information. Apple Intelligence, Agent Mode, selections, and follow-up context remain outside classification.

### Fixes

- Handles macOS Option-Delete through the existing document edit path, recognizes Unicode letters and combining marks, and leaves read-only preview selections unchanged (#696).

- Restore access to AI provider and Jev settings on iPhone and iPad, and improve Jev disclosure text and Done button contrast.
- Sizes the mobile bottom toolbar from its actual container on first layout, keeping editor actions and Settings visible when the observed editor width has not been populated.

### Breaking changes

- None.
