maybe for the business target audience, but I doubt this can be a thing for the majority of users. They just want to get on with their day, not learn magic words to search for and relate to each other.

I tend to use quite old hardware that is powered-off when not in use for its intended purpose and I coined "capability is its own quality".
For dedicated build boxes that crunch through lots of sources (whole distributions, AOSP) but do run seldomly, getting your hands on lots of Cores and RAM very cheaply can still trump buying newer CPUs with better perf/watt but higher cost.
I'm using it for 1-on-1 chats in my family and the application makes you forget that it's smtp/imap/pgp underneath. It feels like a WA clone. Will it disclose past message contents on private key leak? yes.
If you fetch mails via pop3 be aware, you'll move them away before DeltaChat can move them into its own folder via IMAP to build its message threads. If you're doing IMAP only you'll see the messages with your mailclient unless moved. Maybe consider using a dedicated email-alias or account. If the receiving SMTP on submission doesn't strip your connecting IP Address in the Received headers this is quiet a lot on the wire that DC can't do anything about and where you would rely on transport encryption.
It made a point what a thoughtful chat-view, pgp-using email client can do, so I still recommend to give it a try.
> The switch to Btrfs will use a single-partition disk layout, and Btrfs’ built-in volume management. The previous default layout placed constraints on disk usage that can be a difficult adjustment for novice users. Btrfs solves this problem by avoiding it.
good call, subvolumes came to the rescue of the /home partitioning. It's useful, but the inflexibility was in the proper split of available disk space. Novice users then saw warnings for /home - when there was still plenty of space on the root partition.
Setting up and maintaining a mail server is not hard for the initiated, but I fear is archaic and endangered to be irrelevant as basis for interpersonal communication beyond a work context. It has its place as identity provider, able to receive invoices, but this can be subject to change too - and only newsletters and mailing lists will remain.
