# TwitterCldr Changelog

### 6.12.0 (Aug 28th, 2023)
* Upgrade to CLDR v43, ICU 73.2, and Unicode v15.0.0.

### 6.11.5 (Mar 19th, 2023)
* Fix bug causing locale codes to be converted before language lookup (#263)
  - During `TwitterCldr::Shared::Languages.from_code_for_locale(:nn, :en)`, the `:nn` locale code was converted to `:nb` before lookup, causing "Norwegian Bokmål" to be returned instead of "Norwegian Nynorsk".
  - The conversion process uses the likely subtags data to convert locale codes to ones TwitterCLDR supports.
  - I don't remember why that decision was made, but it's definitely wrong. We shouldn't restrict the locale code -> language names dataset to only supported locales, since there's no danger in allowing access to the whole thing.

### 6.11.4 (Nov 2nd, 2022)
* Fix a bug in the CJK break engine causing an int to be compared to nil (#261, @camertron)
  - The code effectively read past the end of an array because it used the wrong counter variable as an index.

### 6.11.3 (Apr 21st, 2022)
* `Currencies#for_code` returns the name of the currency instead of the entry for the "one" plural form (#254, @ur5us)
  - Older versions of CLDR did not include a `name` field for currency data, so a stop-gap measure was taken.

### 6.11.2 (Feb 17th, 2022)
* Replace `BigDecimal.new()` with `BigDecimal()` for ruby 2.7+ compatibility (#251, @jasonpenny)

### 6.11.1 (Jan 18th, 2022)
* Fix calendars importer.
  - Importer was not correctly looking up aliases that contained back references, i.e. '../'.
* Check `Psych::VERSION` instead of `RUBY_VERSION` when parsing YAML.

### 6.11.0 (Dec 29th, 2021)
* Add support for Ruby 3.1.
  - Fixes issue with loading YAML files containing complex types like `Range`, `Time`, etc. Ruby 3.1 comes with Psych 4 which aliases `load` to `safe_load`. The `safe_load` method disallows parsing non-primitve types.

### 6.10.0 (Dec 18th, 2021)
* Fix calendars importer to better respect aliases that point to ancestor locale data.
* Change calendar default format (see: https://github.com/twitter/twitter-cldr-rb/issues/245).

### 6.9.0 (Nov 30th, 2021)
* Forward arguments and block to TZInfo's `#period_for_local` (#243, @DRBragg)

### 6.8.0 (Nov 11th, 2021)
* Upgrade to CLDR v40, ICU 70.1, and Unicode v14.0.0.
* Remove hacky legacy support for the Thai Buddhist calendar.
  - While this is technically a breaking change, I don't think (or rather, hope) that anyone is actually using it.
* Correctly import calendar data respecting ancestor chain.
  - Remove custom Australian calendar data.

### 6.7.0 (July 17th, 2021)
* Upgrade to CLDR v39 and ICU 69.1.

### 6.6.2 (July 8th, 2021)
* Fix additional bugs causing blank strings when formatting lists.

* Fix bug causing blank strings when formatting lists (#241)

### 6.6.0 (March 25th, 2021)
* Support BigDecimal in number localization (#240, @opoudjis)

### 6.5.0 (March 22nd, 2021)
* Upgrade to CLDR v38.1 and ICU 68.2.

### 6.4.0 (November 25th, 2020)
* Upgrade to CLDR v38 and ICU 68.1.

### 6.3.0 (October 28th, 2020)
* Add support for Kazakh (#239, @viroulep).

### 6.2.0 (October 1st, 2020)
* Add support for Esperanto (#238, @viroulep).

### 6.1.0 (August 18th, 2020)
*  Use likely subtags data to supplement locale fallback logic (#236, @mkaplan9)
  - `zh-Hant-TW` should fall back to `zh-Hant`, not `zh`.
  - `es-CR` should fall back to `es-419`, not `es`.

### 6.0.2 (July 28th, 2020)
* Fix issue causing incorrect maximization of locales via likely subtags data.
  - Region codes were being incorrectly identified as language codes, eg CH (Switzerland) was being identified as ch (Chamorro), and AF (Afghanistan) was being identified as af (Afrikaans). This led to und_CH ⇒ ch_Latn_GA instead of ⇒ de_Latn_CH.

### 6.0.1 (May 16th, 2020)
* Fix Chinese list formatter (#233).
* Fix `NoMethodError` thrown when attempting to hyphenate German (and other locales) text (#234).

* Upgrade to CLDR v37, ICU 67.1, and Unicode 13.0.

### 5.4.0 (February 26th, 2020)
* Adds support for the en-001 locale (@SlexAxton).

### 5.3.0 (January 4th, 2020)
* Adds support for Lao, Khmer, and Burmese.

  - Supported scripts now include Chinese, Japanese, Korean, Lao, Thai, Khmer, and Burmese.
* Adds Ruby 2.7 to the build matrix.

### 5.2.0 (December 1st, 2019)
* Improve performance of the text segmentation algorithm.
  - Break engine now uses state tables from ICU instead of regular expressions.
  - It was... embarassing how slow it was before.
* Adds support for line and grapheme cluster segmentation.

### 5.1.0 (November 21st, 2019)
* Upgrade to CLDR v36, ICU 65.1, and Emoji 12.1.
* Full timezone support in formatted dates and times (eg. "Eastern Standard Time" instead of simply "UTC").
* Full day period support (eg. AM, PM, etc).
* Fix bug causing timezone option to not be passed to the underlying datetime formatter.
* Compose locale data from more accurate ancestor list.
* Move date, time, and datetime tokenizers to static methods so they don't have to be re-created for every formatting operation.
* Add support for en-US (how did it take us 7 years to add this??)

### 5.0.0 (October 15, 2019)
* Upgrade to Unicode v12.0.0, CLDR v35.1, and ICU 64.2.
* Fixes several transliteration bugs causing incorrect transform rules to be applied.
* BREAKING: `LocalizedNumber#to_short_decimal` and `LocalizedNumber#to_long_decimal` have been replaced with `LocalizedNumber#to_decimal#to_s(format: :short)` and `LocalizedNumber#to_decimal#to_s(format: :long)` respectively.
