Highlights include Sliding Sync (instant login/launch/sync), Native OIDC (industry-standard authentication), Native Group VoIP (end-to-end encrypted large-scale voice & video conferencing) and Faster Joins (lazy-loading room state when your server joins a room).
The organization does suck, I do agree with that. It still needs a lot of UX improvements too. Though you can turn off read indicators in the settings, and I feel like it is a lot faster then commenting on Lemmy. Lemmy being written in rust is actually causing a lot of issues. It’s not a good language for web applications and it’s really starting to show. It also hasn’t prevented security issues either.
Synapse, the most up to date matrix server, is really slow and resource intensive for sure. But, it’s currently in middle of being replaced with Dendrite. It doesn’t support all the bleeding edge features, but Dendrite has caught up enough to be able to run servers just fine now. In fact Dendrite is light enough to be ran in the mobile Element client, or at least that’s the plan in the near future while they work on p2p. You can read more about it here: https://matrix-org.github.io/dendrite/faq
You can’t disable sending read indicators in Element last I checked, only receiving them. What kind of problems is Lemmy having?
You can check the beehaw writeup if they didn’t defederate already. They’ve been having too many issues with Lemmy, and it’s been a battle with the developers. On Element desktop you can disable sending read receipts, but not mobile which is stupid.
I found this if it’s what you mean, but all it mentions tech-wise is that Lemmy is slow to develop. This does make sense, is it what you’re referring to?
