* Fix a bug that could lead to duplicate links being recorded
for tags.
* 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.
- * 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.
+ * Allow declaring that a dependency is only affected by page presence.
+ (By passing presence => 1 to add_depends.)
+ * pagecount, calendar, postsparkline, progress: Use a presence dependency,
+ which makes these directives much less expensive to use, since page
+ edits will no longer trigger an unnecessary update.
+ * map: Use a presence dependency unless show= is specified.
+ This makes maps efficient enough that they can be used on sidebars!
+ * inline: Use a presence dependency in quick mode.
+ * Transitive dependencies are now correctly supported.
