What's new in 9.3.3
What shipped
- Spell check works again on Windows (#611) — spell check had been off on Windows since 9.1.0. The app handed Electron an empty language list on every launch, which turns the spell checker off outright, and Edit > Spell Checker Language(s) showed every language unchecked. A profile that never picked a language now falls back to your OS locale, and turning spell check off stays off across restarts. If you deliberately turned it off since 9.1.0 this build re-enables it once — uncheck the last language again and it sticks.
- Security updates (#612) — fast-uri 3.1.5 → 3.1.7, clearing four high-severity URI parsing advisories (CVE-2026-75899, CVE-2026-75931, CVE-2026-75975, CVE-2026-76172).
Also includes the Windows-on-ARM installer fix from 9.3.2 (#609) — installers that reported success but left no Close.exe behind.
