chore(deps): bump ex_cldr from 2.43.2 to 2.45.1

[dependabot]

Bumps ex_cldr from 2.43.2 to 2.45.1.

Release notes

Sourced from ex_cldr's releases.

Cldr version 2.45.1

Bug Fixes

• Fix Cldr.Locale.cldr_locale_name/1 to pass through the backend to Cldr.Locale.Match.best_match/2.

Cldr version 2.45.0

Bug Fixes

• Fix unsed require to remove warnings on Elixir 1.20.

Enhancements

• Updates to CLDR 48.1 data.

• Improves matching the desired locale name to an configured CLDR locale name by using Cldr.Locale.Match.best_match/2 function. This better formalises the matching process and is compliant with the CLDR locale matching specification. The matching process is slower than the previous mechanism but more accurate and compliant (there is room for future performance optimization). Configurations with a small number of locales should see no performance difference however raising an issue is encouraged if performance characteristics appear materially worse.

Cldr version 2.44.1

Bug Fixes

• Fix locale data format for locale display names for languages which have a :menu section.

• Fix locale loading to atomize the keys for locale display for languages which have a :menu section.

Cldr version. 2.44.0

Breaking Changes

• Some data formats have changed and the changes are reflected in the locale .json files. These changes should not normally affect consumers since consumers are not normally expected to deal with the underlying data.

  • Relative ordinal date field localized names are now captured as a map not a list. In addition, 2 and -2 ordinal names are added to the data.
  • Locale display names and language names now have a subtype of menu which is a map containing the keys :core, :extension and :default. More or more of these entries may be nil.

Bug Fixes

• Parsing language tags with the und (unknown) language now correctly substituted for a known language name if one can be found in Cldr.Locale.likely_subtags/0. For example:

iex> Cldr.validate_locale("und-TW")
{:ok, TestBackend.Cldr.Locale.new!("zh-Hant-TW")}

• The :gettext_locale_name field of a t:Cldr.LanguageTag.t/0 is now set exactly as returned from Gettext.known_locale_names/1. Previously it was being tranformed to a BCP 47 format locale (replacing "_" with "-"). That is no longer the case.

• Territory containment was previously not considering nested containers and is now doing so. For example, territory "019" (Americas) includes "419" (Latin America and the Carribbean) but "419" was not appearing in the list for "019" since CLDR categorises "grouping" territories separately. This should not affect any consumers, only library writers.

Enhancements

• Update to CLDR 48 data.

• Add Cldr.Locale.Match.best_match/2 and Cldr.Locale.Match.match_distance/3 to implement the CLDR Language Matching algorithm. This is a more formal and testable approach that the previous mechanism. This new function will be use to implement better matching between a known CLDR locale name and supported Gettext locale names. Therefore it is possible that the gettext_locale_name field of a t:Cldr.LanguageTag.t/0 may change with this release.
