Unicode CLDR provides key building blocks for software supporting the world's languages. CLDR data is used by all major software systems (including all mobile phones) for their software internationalization and localization, adapting software to the conventions of different languages.
CLDR v39 had no submission phase. Instead the focus was on modernizing the Survey Tool software, preparing for data submission in the next release (v40). The data fixes in the release were confined to some global changes that are too difficult to do during a submission cycle, and various other fixes. There was a major change in how Norwegian is handled, in order to align the way that the locale identifiers no, nb, and nn are used. The CLDR Github repo is changing the name of “master” branch to “main” branch. The unit support from the last release was integrated into ICU, and some fixes resulting from that process were made to the measurement unit data. Quite a number of fixes are made to the specification, to clarify text or fix problems in keyboards, measurement units, locale identifiers, and a few other areas.
The public beta (data and specification) is planned for 2021-Mar-24, with the release following on 2021-Apr-07.
To find out more, see the draft CLDR 39 Release Note, which has information on accessing the date, reviewing charts of the changes, and necessary migration changes.
