Setting a summaryLength=10 in my hugo.toml does not have any effect since 0.134.0.

To test this, my page Markdown was

The Relearn theme provides configuration options to change your site's colors, favicon and logo. This allows you to easily align your site visuals to your desired style. Most of these options are exposed through so called color variants.

A color variant lets you customize various visual effects of your site like almost any color, used fonts, color schemes of print, syntax highligtning, Mermaid and the OpenAPI shortcode, etc. It contains of a CSS file and optional configuration options in your `hugo.toml`.

I'm pretty sure that the title of this issue is not correct. So, the implementation is simpler:

1. The old implementation converted HTML to plain text, then truncated to whole sentence closest to summaryLength.
2. The new implementation do no conversion to plain, but truncates the HTML to the paragraph closest to summaryLength.

I am okay with it, if this is desired behavior. Although a notice in the release notes would have been great.

I've changed the title of this issue accordingly.

Yea, well, this isn't my day job.

For others reading this; there is a truncate func (https://gohugo.io/functions/strings/truncate/) that understands HTML that can be used for more ... fine grained control over the length.

I've updated the documentation to reflect the behavioral change:

• https://gohugo.io/getting-started/configuration/#summarylength
• https://gohugo.io/content-management/summaries/#automatic-summary
• https://gohugo.io/content-management/summaries/#alternative
