Since 0.134.0, I need to use the plainify function to get the plain text of the summary, but the problem is that {{ .Summary | plainify }} is not exactly the same as the previous {{ .Summary }} . The former will preserve line breaks, while the latter is spaces.
Have you considered adding a new parameter to the plainify function to control whether to preserve line breaks?
By the way, it seems that when Bing search analyzes SEO issues, it only reads the first line of the description. Then a lot of SEO error alerts about description being too short will be generated.
