++ 							*tag-old-static*
++ Until March 2019 (patch 8.1.1092) an outdated format was supported:
++     {tagfile}:{tagname} {TAB} {tagfile} {TAB} {tagaddress}
++ 
++ This format is for a static tag only.  It is obsolete now, replaced by
++ the second format.  It is only supported by Elvis 1.x, older Vim versions and
++ a few versions of ctags.  A static tag is often used for functions that are
++ local, only referenced in the file {tagfile}.  Note that for the static tag,
++ the two occurrences of {tagfile} must be exactly the same.  Also see
++ |tags-option| below, for how static tags are used.
++ 
++ The support was removed, since when you can update to the new Vim version you
++ should also be able to update ctags to one that supports the second format.
