1. We will be able to read variable passed like this. In additional chat variables `Old way passed variable name` just enter `username`. This will improve compatibility with older embed codes.
```
LHCChatOptions =
  {
      "attr_prefill": [
          {
              "name": "username",
              "value": "remdex"
          }
      ]
  }
```
2. `{args.` will be supported in canned messages and canned messages replace variables. E.g `{args.chat.chat_variables_array.player.firstName}`
3. Various small bugfixes.
