  2. 버전 0.9.0

    • 개선Subtitle translation works on whole sentences, then splits them back over the original lines: far fewer broken or garbled fragments.

    • 개선First visit opens in your language, guessed from your browser and time zone (nothing is sent anywhere), with a one-click switch.
    • 새 기능Support the project page: give by card, PayPal, Buy Me a Coffee, Ko-fi, crypto (with QR codes) or bank transfer, plus other ways to help. Help and the ticket form now live on the contact page.
