It took a while but it's shaping up nicely :) Post-Quantum Cryptography and Reliable Deletion, better known as Forward Secrecy, are going to become available in 2026 in #deltachat. For more details, including the recent #fosdem26 talk recording:

will there be a possibility of unable to decrypt errors if one of the parties in a chat is offline (with their devices powered off, and such) for over 10 days and then comes back?

@zaire should be fine, see also ietf.org/archive/id/draft-auto…
When coming online a device will first ingest pending messages, then destroy expired decryption keys.

Autocrypt v2 OpenPGP Certificates and Transferable Secret Keys

This document describes the "Autocrypt v2 Certificate", a standard structure for an OpenPGP certificate for Internet messaging. It offers defense against store-now-decrypt-later attacks from quantum computers through post-quantum hybrid cryptography.

speaking of deletion, does delta chat do anything to ensure deleted messages are gone for good from the device (so the data isn’t recoverable via forensics tools even if applied right away)?

@zaire Unfortunately, on systems which use flash storage like a typical smartphone or laptop with SSDs, the application can't influence when data is getting overwritten, unless it overwrites all unallocated space with zeros: baeldung.com/linux/wipe-free-s…
