* mirrorlist: Display nothing if list is empty.
* 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 is only affected by page presence
+ or changes to its links.
+ (By passing presence => 1 or links => 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.
+ * brokenlinks: Use a link dependency.
+ This makes it much more efficient, only updating when really necessary.
+ * orphans, pagestats: Use a combination of precense and link dependencies.
+ This makes them more efficient. It also fixes a longstanding bug,
+ where if only a small set of pages were considered by orphans/pagestats,
+ changes to links on other pages failed to cause an update.
+ * Transitive dependencies are now correctly supported.

Warning: Any change to the sidebar will cause a rebuild of the whole wiki,
since every page includes a copy that has to be updated. This can
-especially be a problem if the sidebar includes [[inline]] or [[map]]
-directives, since any changes to pages inlined or mapped onto the sidebar
+especially be a problem if the sidebar includes an [[ikiwiki/directive/inline]]
+directive, since any changes to pages inlined into the sidebar
will change the sidebar and cause a full wiki rebuild.
+
+Instead, if you include a [[ikiwiki/directive/map]] directive on the sidebar,
+and it does not use the `show` parameter, only adding or removing pages
+included in the map will cause a full rebuild. Modifying pages will not.
Use this when constructing the filename of a html file. Use `urlto` when
generating a link to a page.
-#### `add_depends($$)`
+#### `add_depends($$;@)`
Makes the specified page depend on the specified [[ikiwiki/PageSpec]].
+By default, dependencies are full content dependencies, meaning that the
+page will be updated whenever anything matching the PageSpec is modified.
+This default can be overridden by additional named parameters, which can be
+used to indicate weaker types of dependencies:
+
+* `presence` if set to true, only the presence of a matching page triggers
+ the dependency.
+* `links` if set to true, any change to links on a matching page
+ triggers the dependency. This includes when a link is added, removed,
+ or changes what it points to due to other changes. It does not include
+ the addition or removal of a duplicate link.
+
#### `pagespec_match($$;@)`
Passed a page name, and [[ikiwiki/PageSpec]], returns true if the
* `add_depends($page, $spec, links => 1, presence => 1)`
adds a links + presence dependency.
-* `refresh` only rebuilds a page with a links dependency if
- pages matched by the pagespec gain or lose links. (What the link
- actually points to may change independent of this, due to changes
- elsewhere, without it firing.)
+* Use backlinks change code to detect changes to link dependencies too.
* So, brokenlinks can fire whenever any links in any of the
pages it's tracking change, or when pages are added or
removed.
