No 'version' key in the manifest file for custom integration 'yeelight_v2'

Got this in my logs today. I haven't updated to 2121.6 yet and wanted to warn others as I dont think the integration will work in the latest version.

2021-04-23 14:47:44 WARNING (MainThread) [homeassistant.loader] No 'version' key in the manifest file for custom integration 'yeelight_v2'. As of Home Assistant 2021.6, this integration will no longer be loaded. Please report this to the maintainer of 'yeelight_v2'

Waiting for PR approval.
Meanwhile you may manually add the version key to manifest.json:

{
  "domain": "yeelight_v2",
  "name": "YeelightV2",
  "version": "1.0.0",
  "documentation": "https://www.home-assistant.io/integrations/yeelight",
  "codeowners": [
    "@rytilahti",

  ],
  "config_flow": true
}
