This plugin changes the previous/next links below the posts to reflect the category index instead of the global index. This way, the categories of a blog behave more like independent subblogs.

There is no configuration needed, but i recommend to replace the blog index by a static page to avoid confusing readers. This can be archived by setting INDEX_PATH to some subdirectory, adding pages output to the root directory

PAGES = (
  ("pages/*.md", "", "page.tmpl"),
)

and creating a corresponding pages/index.md file.

This plugin replaces section_prevnext from v7.
