* `2` group
* `3` public

### Participant types
* `1` owner
* `2` moderator

## Capabilities

### 3.0 (Initial Talk release)
* `audio` - audio is supported
* `video` - video + screensharing is supported
* `chat` - simple text chat is supported, superseded by `chat-v2`

### 3.1
* `guest-signaling` - Guests can do signaling via api endpoints
* `empty-group-room` - Group rooms can be created without inviting a Nextcloud user group by default

### 3.2
* `guest-display-names` - Display names of guests are stored in the database, can be set via API (not WebRTC only) and are used on returned comments/participants/etc.
* `multi-room-users` - Users can be in multiple rooms at the same time now, therefor signaling now also requires the room/call token on the URL.
* `chat-v2` - Chat messages are now [Rich Object Strings](https://github.com/nextcloud/server/issues/1706) and pagination is available, the previous `chat` is not available anymore.
