We're moving from the 1.x versioning to 4.x to align Mailbird Next with Mailbird Classic as a new major version upgrade as we prepare for the product launch. This is a versioning alignment step, not a sign of a skipped public release or a separate upgrade requirement.

✨ New Features

🌐 Data import in your language — The Mailbird Classic import now speaks all 30 supported languages, from the first welcome screen through to the final summary.

🔁 No more duplicate calendar entries — Birthdays and events under an Outlook account no longer appear twice until you restart.
💬 ChatGPT app stays responsive — Fixed the freeze that could lock up the ChatGPT app panel.
