title: How can I change the "Read More" text for a post preview when using post.preview instead of post.get_preview in Timber?
body: <p>Before Timber version 1.3.1, if you wanted to change the Read More text for a post preview, you could use <code>{{ post.get_preview(50, 'false', 'Keep Reading') }}</code>. This function has been deprecated and it is recommended to use <code>{{ post.preview }}</code>, but it doesn't seem to have the ability to filter the Read More text easily.</p>
