Timber upgrade 1.19 site.language deprecated?

Question

I notice since Timber version 1.19, the {% if site.language == ‘pt-PT’ %} stopped working. I have WPML.

When I downgrade to 1.18.2, it’s working.

I use this workaround in my staging site:

{% if site.link == 'https://mywebsite.com' %}

but I would prefer a better alternative.

I’m planning to upgrade Timber, but step by step.
