Jekyll 4.0.0 has been out for almost two months now, yet GitHub Pages still uses Jekyll 3.8.5. The differences in 4.0.0 features described in the documentation (such as the new {% link %}
behaviour) make it a pain to be backwards compatible for GitHub Pages.
Does anyone know the typical amount of time GitHub Pages takes to adopt new Jekyll versions? Or a place where they might share these kind of timelines?
