No 'version' key

2021-05-14 08:55:24 ERROR (MainThread) [homeassistant.loader] No 'version' key in the manifest file for custom integration 'kuna'. As of Home Assistant 2021.6, this integration will no longer be loaded. Please report this to the maintainer of 'kuna'

Not sure if this was being enforced previously, but it is now and prevents the integration from being installed. When adding the Kuna Integration from Configuration I get an error Config flow could not be loaded. Upon checking the logs it provides more details the version key needs to be included in the manifest.json

The custom integration 'kuna' does not have a valid version key (None) in the manifest file and was blocked from loading. See https://developers.home-assistant.io/blog/2021/01/29/custom-integration-changes#versions for more details

I'm running Home Assistant 2021.6.0b1 and version 9.1 of the Kuna Smart Home Security integration. I also confirmed that if I edit the manifest.json and add a version key, the integration installs and works great without any further errors.
