Changes

== Dummy edit ==

If the wikitext is not changed no edit will be recorded and the edit summary is discarded.

A dummy edit is a change in wikitext that has no effect on the rendered page, such as changing the number of [[wW:newline|newlinenewlines]]s at some position from 0 to 1 or from 2 to 3 or conversely (changing from 1 to 2 makes a difference, see below). This allows an edit summary, and is useful for correcting a previous edit summary, or an accidental marking of a previous edit as "minor" (see below). Also it is sometimes needed to refresh the cache of some item in the database, see e.g. [[Help:Category#A_category_tag_in_a_template.3B_caching_problem|A category tag in a template; caching problem]].
