CLDR 34 included a full Survey Tool data collection phase increasing to 85 languages at the “modern” (full) level, 4 at the lower “moderate” level (suitable for document content), 18 at the basic level, and about 100 others that don’t meet the level requirements.
Among the other changes: new units were added (e.g., atmosphere, petabyte); many new emoji keywords and names were corrected/refined, with updated emoji sort order; and preparations for the New Japanese Era (affecting most software for Japan) were made. The specification was also updated with many changes for Unicode Locale Identifier and BCP 47 Conformance sections, plus defining the syntax of unit identifiers. For other changes, details, and links to documentation, see the CLDR 34 Release Notes.
