* Added support framework for multiple types of dependencies.
* Allow declaring that a dependency does not encompass the content of a
page. (By passing content => 0 to add_depends.)
- * pagecount: Use a contentless dependency, which makes this
- directive much less expensive to use, since page edits will
- no longer trigger an unnecessary update of the page count.
+ * pagecount, calendar: Use a contentless dependency, which makes these
+ directives much less expensive to use, since page edits will
+ no longer trigger an unnecessary update.
* map: Use a contentless dependency unless show= is specified.
This makes simple maps efficient enough that they can be used on sidebars!
* inline: Use a contentless dependency in quick mode.
