[Delta Chat](https://delta.chat) is an e-mail based messenger that works on all platforms. Apart from an Whatsapp/Telegram-style user interface it features a security-audited [Rust-core library](https://github.com/deltachat/deltachat-core-rust), server [templates for setting up a state-of-the-art e-mail server](https://delta.chat/en/serverguide), many different bots, Matterbridge support and, last but not least, a way write standard web apps that can be shared in a chat (https://webxdc.org) which is now also experimentally supported by the XMPP Android messenger Cheogram. The talk will both discuss and demonstrate other unique features, among them QR-code based onboarding and support for protection against machine-in-the-middle attacks against end-to-end encryption, and we'll also provide glimpses in what's brewing for 2023/2024.
