Just released version 1.7.0 of Kumo:
https://github.com/catacombing/kumo/releases/tag/v1.7.0
The most significant change is the introduction of Servo as an optional rendering engine besides WebKit.
Originally wanted to give this some more time to cook, but my hand was forced after updating my WebKit fork to the latest version of WebKit.
Easiest way to try is Flatpak, it should be available there in a couple hours.
