+This is the changelog for Cldr v2.37.2 released on July 4th, 2023.  For older changelogs please consult the release tag on [GitHub](https://github.com/elixir-cldr/cldr/tags)
 
 **Note that `ex_cldr` version 2.33.0 and later are supported on Elixir 1.11 and later only.**
 
 ### Bug Fixes
 
 * Remove checking Phoenix and Ecto json_library configurations.  Ecto no longer configures its `:json_library` in `config.exs` and checking for Phoenix configuration can cause config failures when [building in Docker](https://github.com/elixir-cldr/cldr/issues/208). Thanks to @maciej-szlosarczyk for the report. Closes #208.
 
+### Enhancements
+
+* Improves parsing of language tag extensions. Primarily intended to improve support for [tempo](https://github.com/kipcole9/tempo).

+> #### `Change to :json_library configuration` {: .warning}
+>
+> As of `ex_cldr` version 2.37.2 the configuration parameter `:json_library`
+> does not attempt to read the configuration of either Phoenix of Ecto.
+>
+> Specifing the `:json_library` parameter under the `:ex_cldr`
+> configuration key in `config.exs` is recommended however the availability 
+> of `Jason` or `Poison` will still be automatically detected and configured 
+> if the `:json_library` key is not set.

 ## Introduction
 
 `ex_cldr` is an Elixir library for the [Unicode Consortium's](http://unicode.org) [Common Locale Data Repository (CLDR)](http://cldr.unicode.org).  The intentions of CLDR, and this library, is to simplify the locale specific formatting and parsing of numbers, lists, currencies, calendars, units of measure and dates/times.  As of April 28th 2023 and `ex_cldr` Version 2.37.0, `ex_cldr` is based upon [CLDR version 43.0](http://cldr.unicode.org/index/downloads/cldr-43).
