Before Timber version 1.3.1, if you wanted to change the Read More text for a post preview, you could use {{ post.get_preview(50, 'false', 'Keep Reading') }}. This function has been deprecated and it is recommended to use {{ post.preview }}, but it doesn't seem to have the ability to filter the Read More text easily.

It doesn’t seem easy, probably because it isn’t documented yet. But we’re working on it!
{{ post.preview }} returns a PostPreview object, which is a chainable object. This means that you can change the output of the preview by adding methods.
In your example, when you want to change the read-more text:
{{ post.preview.read_more('More!') }}
If you’d also want to change the length to 10 words only, you could do something like this:
{{ post.preview.length(10).read_more('More!') }}

3post.preview.length(10) only works if I add .force at the end. – Michel Moraes Sep 23 '18 at 18:53

.force at the end is vital! – Alchem Oct 31 '18 at 13:25

Perfect! @MichelMoraes! Also to hide, we set false into parenthesis. Like that `{{post.preview.length(25).force.read_more(false)}}` – samu101108 Oct 03 '21 at 23:46
