ICU 67.1

Note: Please ignore the "Source code" zip & tar.gz files. (They are auto-generated by GitHub and omit the LFS file contents.)

We are pleased to announce the release of Unicode® ICU 67.

ICU 67 updates to CLDR 37 locale data with many additions and corrections. This release also includes the updates to Unicode 13, subsuming the special CLDR 36.1 and ICU 66 releases. ICU 67 includes many bug fixes for date and number formatting, including enhanced support for user preferences in the locale identifier. The LocaleMatcher code and data are improved, and number skeletons have a new “concise” form that can be used in MessageFormat strings.

This is the first regular release after ICU 65. ICU 66 was a low-impact release with just Unicode 13 and a few bug fixes.
