Bilingual translation output: New Translation Output setting: insert the translation on its own, or together with the original text — each line tagged with the matching language flag Choose between Translation Only, Original + Translation, or Translation + Original. Bilingual modes are part of Babel Fish Pro. Clearer guidance when "Allow Full Access" is off, so the keyboard can reach the AI. Stability and error-message improvements. New: Automatic sentence capitalization • The keyboard now auto-capitalizes the first letter of a sentence — the start of the text and the first letter after ". ", "! " or "? ". This applies both while typing and to AI/translation output. • The Shift (⇧) key now lights up and shows uppercase letters whenever the next letter will be auto-capitalized, like the native keyboard. • New "Auto Capitalization" toggle in the keyboard's Settings (ON by default). Turn it off to type with no auto-capitalization. Also fixed • Selecting an AI model in the keyboard's Settings (AI Model) no longer crashes/closes the keyboard on Pro accounts. What to test 1. Open the keyboard, tap Settings, confirm "Auto Capitalization" is ON. 2. Type: hello. how are you? i'm fine! → should render "Hello. How are you? I'm fine!" and the ⇧ key should light up after each ". " / "! " / "? ". 3. Select some lowercase text and tap Translate → the inserted result should be sentence-capitalized. 4. Paste/type a URL or email (e.g. https://example.com/test. hello) in the translation flow → the link stays intact, only "hello" → "Hello". 5. Turn the toggle OFF → typing and output keep their original casing. 6. Settings → AI Model → scroll and select a model → keyboard stays open and applies the selection (no crash).
