Lightning is not included or installable in Thunderbird 54
As of the update yesterday, Lightning disappeared from Thunderbird. I am on the beta update channel. Further, trying to manually install it fails with an unsupported version message.

Still getting 'Lightning could not be installed because it is not compatible with Thunderbird 54.0.' Addons -> Gear -> Install add-on from file -> lightning-5.6a2.en-US.win32.xpi
Thank you very much, that worked!
