## Cldr_Currencies v2.6.1
This is the changelog for Cldr_Currencies v2.6.1 released on July 19th, 2020. For older changelogs please consult the release tag on [GitHub](https://github.com/elixir-cldr/cldr_currencies/tags)

## Cldr_Currencies v2.6.0
This is the changelog for Cldr_Currencies v2.6.0 released on July 18th, 2020. For older changelogs please consult the release tag on [GitHub](https://github.com/elixir-cldr/cldr_currencies/tags)
### Breaking change
* Remove `Cldr.Currency.make_currency_code/1` whose need is replaced by `Cldr.validate_currency/1`.
### Deprecations
* Deprecate `Cldr.Currency.known_currency?/1` in favour of `Cldr.Currency.known_currency_code?/1`
* Deprecate `Cldr.Currency.known_currencies/0` in favour of `Cldr.Currency.known_currency_codes/0`
### Enhancements
* Support the creation of private use currencies with `Cldr.Currency.new/2`. Newly created private use currencies are stored in an `:ets` table which means that currencies will need to be recreated on each application restart. Creating the currencies is a developer responsibility although this may change in the future. In order to create currencies a supervisor and `:ets` table owner must be started. See the [README](README.md) for further details on adding the private use currency store to your application supervision tree.
* Add `:alt_code` to the `Cldr.Currency` struct. When creating a new currency, the currency code must conform to ISO4217 meaning that any new code must be in the "private use" range. This in turn means that the currency code must start with "X" and be three characters long. Many crypto currencies have either conflicting currency codes (do not comply with ISO4217 private use) or are invalid codes (longer than three characters). The `:alt_code` can be used to store an arbitrary alternative currency code than can be used to identify cryptocurrencies by a more familiar code.
## Cldr_Currencies v2.5.0
This is the changelog for Cldr_Currencies v2.5.0 released on May 2nd, 2020. For older changelogs please consult the release tag on [GitHub](https://github.com/elixir-cldr/cldr_currencies/tags)
### Enhancements
* Add `Cldr.Currency.currency_from_locale/{1, 2}`
* Add `Cldr.Currency.current_currency_from_locale/1`
* Add `Cldr.Currency.current_currency_from_territory/1`
* Add `Cldr.Currency.currency_format_from_locale/1`
* Add `<backend>.currency_from_locale/{1, 2}`
## Cldr_Currencies v2.4,1
This is the changelog for Cldr_Currencies v2.4.1 released on November 7th, 2019. For older changelogs please consult the release tag on [GitHub](https://github.com/elixir-cldr/cldr_currencies/tags)

## Cldr_Currencies v2.4.0
This is the changelog for Cldr_Currencies v2.4.0 released on November 6th, 2019. For older changelogs please consult the release tag on [GitHub](https://github.com/elixir-cldr/cldr_currencies/tags)
### Enhancements
* Adds the options `:only` and `:except` to `Cldr.Currency.filter_currencies/3`. These options are exercised in [ex_money](https://hex.pm/packages/ex_money) in the `Money.parse/2` function to limited parsed user input to a particular set of currencies.

This is the changelog for Cldr_Currencies v2.2.4 released on March 15th, 2019. For older changelogs please consult the release tag on [GitHub](https://github.com/elixir-cldr/cldr_currencies/tags)
### Enhancements
* Makes generation of documentation for backend modules optional. This is implemented by the `:generate_docs` option to the backend configuration. The default is `true`. For example:
```elixir
defmodule MyApp.Cldr do
use Cldr,
default_locale: "en-001",
locales: ["en", "ja"],
gettext: MyApp.Gettext,
generate_docs: false
end
```

* Adds `Cldr.Currency.currency_history_for_locale/2`
* Adds `Cldr.Currency.current_currency_for_locale/2`
* Adds `Cldr.Currency.territory_currencies/0`
Some examples:
```
iex> Cldr.Currency.territory_currencies |> Map.get("LT")
%{
EUR: %{from: ~D[2015-01-01], to: nil},
LTL: %{from: nil, to: ~D[2014-12-31]},
LTT: %{from: nil, to: ~D[1993-06-25]},
SUR: %{from: nil, to: ~D[1992-10-01]}
}
iex> Cldr.Currency.currency_history_for_locale "en", MyApp.Cldr
%{
USD: %{from: ~D[1792-01-01], to: nil},
USN: %{tender: false},
USS: %{from: nil, tender: false, to: ~D[2014-03-01]}
}
iex> Cldr.Currency.current_currency_for_locale "en", MyApp.Cldr
:USD
iex> Cldr.Currency.current_currency_for_locale "en-AU", MyApp.Cldr
:AUD
```
## Cldr_Currencies v2.1.4
This is the changelog for Cldr_Currencies v2.1.4 released on February 22nd, 2019. For older changelogs please consult the release tag on [GitHub](https://github.com/elixir-cldr/cldr_currencies/tags)
### Bug Fixes
* Fixes significant performance regression in `Cldr.Currency.currencies_for_locale/2`. Thanks to @doughsay for the issue. Closes #98 in [money](https://github.com/elixir-cldr/money).
## Cldr_Currencies v2.1.3
This is the changelog for Cldr_Currencies v2.1.3 released on February 18th, 2019. For older changelogs please consult the release tag on [GitHub](https://github.com/elixir-cldr/cldr_currencies/tags)
### Bug Fixes
* Updates `ex_cldr` to fix the regex that parses currency names used for money parsing
## Cldr_Currencies v2.1.2
This is the changelog for Cldr_Currencies v2.1.2 released on February 13th, 2019. For older changelogs please consult the release tag on [GitHub](https://github.com/elixir-cldr/cldr_currencies/tags)
### Bug Fixes
* Some different currencies may have the same currency name. This most commonly happens when there are historic currencies with the same name as a current currency. Afghan Afghanis, for example, has the code `:AFA` until 2002 when it was replaced by the currency code `:AFN`. Now when extracting currency strings, the currency names map only to the current currency and the duplicated are therefore removed.
## Cldr_Currencies v2.1.1
This is the changelog for Cldr_Currencies v2.1.1 released on February 10th, 2019. For older changelogs please consult the release tag on [GitHub](https://github.com/elixir-cldr/cldr_currencies/tags)
### Bug Fixes
* Fixes the regex for parsing currency names that have date ranges in them. It now correctly parses names with non-ASCII characters too.
* Removes `Cldr.Currency.all_currency_strings/2` since strings conflict across locales
* Add `Cldr.Currency.currency_strings/2`
### Enhancements
* Added `:unannotated` to `Cldr.Currency.currency_filter/2`. It omits currency names that have a "(...)" in then since these are typically financial instruments.
## Cldr_Currencies v2.1.0
This is the changelog for Cldr_Currencies v2.1.0 released on February 9th, 2019. For older changelogs please consult the release tag on [GitHub](https://github.com/elixir-cldr/cldr_currencies/tags)
### Enhancements
The primary goal of this release is to provide a mechanism to support parsing money and currency input from a user. With this in mind, this release adds:
* `Cldr.Currency.currency_strings/2` that returns a list of strings for a currency in a locale against which user input can be compared to identify a currency
* `Cldr.Currency.all_currency_strings/2` which returns a similar list but for all known locales
* `Cldr.Currency.currency_filter/2` that will filter a list currencies based upon whether they are current, historic or legal tender
In addition the `Cldr.Currency.t` structure has changed:
* The `Cldr.Currency.t` struct now includes effective dates `:to` and `:from`. These were previously encoded in the currency name. The currency name no longer includes these dates.
## Cldr_Currencies v2.0.0
This is the changelog for Cldr_Currencies v2.0.0 released on November 22nd, 2018. For older changelogs please consult the release tag on [GitHub](https://github.com/elixir-cldr/cldr_currencies/tags)
### Enhancements
* Updated dependency on [ex_cldr](https://hex.pm/packages/ex_cldr) to version 2.0.0.
* Remove Poison from optional dependencies (can still be configured in a client app)
### Breaking Changes
* `Currency.currency_for_code/3` has a changed function signature and it now requires a backend module to be specified. It also supports an option `:locale` to specify the locale. The default is the default locale of the specified backend.
```
Cldr.Currency.currency_for_locale(:USD, MyApp.Cldr, locale: "en")
```
The @spec for the new signature is:
```
@spec currency_for_code(code, Cldr.backend(), Keyword.t()) ::
{:ok, t} | {:error, {module(), String.t()}}
```
