- Thanks to Furamako for the Spanish translation
- Thanks to [ZomkaDEV](https://github.com/ZomkaDEV) for the Russian translation
- Thanks to [@ch1tmdgus](https://github.com/ch1tmdgus) (N4C) for the Korean translation
- Thanks to [@bruuhim](https://github.com/bruuhim) for the Arabic translation
- Thanks to [@jaydenjcpy](https://github.com/jaydenjcpy) for the Chinese (Traditional) translation
- Thanks to [@darthplagueiswise](https://github.com/darthplagueiswise) (Radan) for the experimental flag feature set
- Thanks to [@asdfzxcvbn](https://github.com/asdfzxcvbn) for [zxPluginsInject](https://github.com/asdfzxcvbn/zxPluginsInject) and [ipapatch](https://github.com/asdfzxcvbn/ipapatch)

- Preserved unsent messages can't be removed via "Delete for you"; pull-to-refresh clears them (warning available in settings)
- "Delete for you" detection uses a ~2s window after the local action — a real unsend landing in that window may be missed (rare)
- With Liquid Glass buttons + Hide UI on capture both on, the DM eye leaves an empty glass bubble in captures
