+## Overview
+
+Unicode CLDR provides key building blocks for software supporting the world's languages. 
+CLDR data is used by all [major software systems](https://cldr.unicode.org/index#TOC-Who-uses-CLDR-) (including all mobile phones) for their software internationalization and localization, adapting software to the conventions of different languages.
+
+The largest changes in this release were the updates to Unicode 16.0, substantial additions of Emoji search keyword data, and ‘upleveling’ the locale coverage.

+
+**TBD**
+
+## Data Changes

+**TBD**
+2. Added new numbering systems from Unicode 16.0
+
+For a full listing, see [Delta DTDs](https://unicode.org/cldr/charts/46/supplemental/dtd_deltas.html).
+
+### Supplemental Data Changes
+
+1. Currency. New currency code ZWG added — because it was late in the cycle, many locales will just support the code.
+**TBD**

+	2. Deprecated timezone ids. Altered the handling of: CST6CDT, EST, EST5EDT, MST7MDT, PST8PDT
+3. Units

+	2. Changed preferred wind speed preference for some locales to 	meter-per-second
+4. Updated: language IDs, likelySubtags, region gdp and language populations, etc.
+   1. Minimization for likelySubtags removes some additional redundant mappings
+5. Transforms.
+   1. Major update to Han → Latn, reflecting new data in Unicode 16.0
+   2. Fixes for Arabic numbers, a Farsi vowel
+
