 After a new major revision of Notepad++ is released (like from v7.x to v8.x), there will be a few versions of the manual that still contain mentions of the previous major-revision specifics, but eventually those specifics will be removed.  When a major version is no longer discussed in the Online User Manual, this History page will link to the last User Manual release with specifics to that major version.  (A similar process may be used for smaller revisions (like v8.x to v8.y), if the User Manual maintainers feel that the historical notes need to be reduced.)
