Which Unicode Emoji report version was first approved in June 2015?

The first Unicode Emoji report version approved in June 2015 was Emoji 1.0.

Unicode Technical Report #51 began as a series of drafts before its first approved publication. The document’s first published version was labeled Version 1.0 and dated June 9, 2015. Unicode’s announcement later described that first version as being released alongside Unicode 8.0, which added new emoji characters and skin-tone modifier characters.

The numbering can be confusing because “Emoji 1.0” is the report’s version, not the number of emoji in existence and not a Unicode character version. Unicode also uses version numbers for its main standard, while emoji data and report revisions have their own labels.

Later report versions expanded the inventory and documented features such as gendered sequences, flags, modifiers, and zero-width-joiner combinations. Thus Emoji 5.0 and Emoji 11.0 are later milestones, not the first approved June 2015 release. The key historical marker is Version 1.0, first approved in revision 3.
