has been moved to the new sortnaturally plugin, which is not enabled
by default since it requires the Sort::Naturally perl module.
- * TMPL_INCLUDE is no longer supported in any template used by ikiwiki.
- It used to be allowed in certian templates, but not in others.
-
* The add_templates option has been removed from the underlay plugin.
If you used this option, you can instead use templates/ subdirectories
inside underlay directories added by the add_underlays option.
