alt Hacker NewsFirst impression: it has a tutorial, which should actually help increase the player base quite a bit.
It comes with some movement quality of life (e.g. moving into a door opens it, moving into an obviously dangerous thing requires confirmation).
If you enable the option, there's color coding of health (green -> full), burden level, and states like poisoning, which I think is new too.
You can filter out messages like "you have displaced your pet".
IIRC, there was always a way to filter out certain messages (or that may be an alt.org customization, but it's been a part of my config file for a while now).
