# Group DMs, custom sender names and channel controls

_Release #004, February 20, 2026. Slack, Teams & email_

Viktor now works in group DMs, scheduled tasks can post under custom names, and you can ask Viktor to leave channels.

- **Group DM support.** Viktor can now join and participate in group direct messages (multi-person DMs), not just channels and 1:1 conversations. Mention him in any group DM to get started.
- **Custom sender names for scheduled tasks.** Scheduled tasks can now post messages under a custom display name instead of always appearing as "Viktor."
- **Leave channel on request.** You can now ask Viktor to leave a Slack channel. Both joining and leaving channels go through a confirmation step so nothing happens by accident.
