Unicode CLDR 24 has been released, providing an update to the key building blocks for software supporting the world's languages. This data is used by a wide spectrum of companies for their software internationalization and localization, adapting software to the conventions of different languages for such common software tasks.
Unicode CLDR 24 focused on additional structure for formatting units, dates, and times, and improving data coverage. This version contains data for 238 languages and 259 territories—740 locales in all. Ten languages were added to the 100%-modern-coverage list for a total of 70 languages. Between the new languages, and the new structure, more data was entered than in any previous release.

The new structure focused primarily on formatting of units and improvements to date and time formatting.

• fractional plural forms. major extension to handle fractions (eg, some languages use the equivalent of “1.2 teaspoons” but “2.1 teaspoon”)
• measurement units. many additional unit types (“10.3 kg”), in up to 6 plural forms per language
• compound units. video length: "23 hrs, 7 mins", or "23:07"
• dates/times. new relative fields such as "last Sunday", and "now"; 12 hour time formats that omit "am/pm"; neutral eras ("405 BCE"); additional timezone falback regional patterns ("{city} Daylight Time")
• number formatting. exponential notation (1.42×10²³), at-least ("99+"), ranges ("3.5-4.5 kg"), narrow currency symbols (both "US12ドル.23" and "12ドル.23").
• collation. major simplification of rule syntax, updated root files to Unicode 6.3; preliminary version of European Ordering Rules; documentation of the CLDR Collation Algorithm (extending UCA)
• JSON. improved support, including new structure and data.

In addition, the data already present from CLDR v23 was reviewed for the supported languages, and many improvements made.

Details of coverage improvements and new features are provided in http://cldr.unicode.org/index/downloads/cldr-24, along with a detailed Migration section.

May 1, 2013 — The Unicode CLDR 24 Survey Tool is open for data submission starting today. CLDR provides key building blocks for software to support the world's languages, with the largest and most extensive standard repository of locale data available. The survey tool is an online tool used by organizations and individuals to contribute data to this repository, and to vote on alternative contributions. For a complete description of the new enhancements and features in the CLDR survey tool, please see http://cldr.unicode.org/index/survey-tool/whats-new
