If you want paragraph-level permalinks in your blog posts, there's a new directive, #flPgfPermaLinks.
If you set it to "true" your posts will have them, "false" to turn the feature off.
They are off by default.
If they're on, each paragraph in your blog post will have a small purple hash sign, that links to the paragraph. If a reader wants to point to a specific paragraph in the post, they can use the URL from the hash sign.
The link is formed from the first characters of the first five words in the paragraph. You can move the paragraph around on the page without breaking links. However, if you change one of the first five words in the paragraph, links to it will break.
If you want the feature on by default for your websites, you can put the directive in your cmsPrefs.opml file.
