Changelog Entry

Fixed

• Fixes #4403. Bump to CLDR v37 and remove adopted cldr-data and cldr-data-downloader packages, by @compulim, in PR #4874

Description

We are bumping CLDR to v37 from the official Unicode repository, despite the current is v43.

We adopted cldr-data and cldr-data-downloader to fix their vulnerabilities and patching plurals for Polish and Portuguese language (bug of CLDR v36). However, we no longer need both packages as we download from the official Unicode repository.

Design

globalize does not support CLDR v38 or up due to new "c" parameter added to French plurals and globalize did not update its dependency on make-plural package. Thus, we cannot bump to v38 or beyond until globalize resolved the issue.

Specific Changes

• Imports CLDR from cldr-core and other packages
• Removes cldr-data and cldr-data-downloader
• Moved Polish and Portuguese plurals patch to createPrecompileGlobalize script

• I have added tests and executed them locally
• I have updated CHANGELOG.md
• I have updated documentation
