CHANGELOG.md
# Changelog for Cldr_Dates_Times v2.2.2
This is the changelog for Cldr_Dates_Times v2.2.2 released on August 31st, 2019. For older changelogs please consult the release tag on [GitHub](https://github.com/elixir-cldr/cldr_dates_times/tags)
### Changes & Deprecations
* Deprecates the option `:format` on `Cldr.DateTime.Relative.to_string/3` in favour of `:style`. `:format` will be removed with `ex_cldr_dates_times` version 3.0
### Bug Fixes
* Return an error tuple immediately when a format code is used but no data is available to fulfill it
# Changelog for Cldr_Dates_Times v2.2.1
This is the changelog for Cldr_Dates_Times v2.2.1 released on August 23rd, 2019. For older changelogs please consult the release tag on [GitHub](https://github.com/elixir-cldr/cldr_dates_times/tags)
### Bug Fixes
* Fix `@spec` for `Cldr.Date.to_string/3`, `Cldr.Time.to_string/3` and `Cldr.DateTime.to_string/3` as well as the `!` variants.
# Changelog for Cldr_Dates_Times v2.2.0
This is the changelog for Cldr_Dates_Times v2.2.0 released on August 23rd, 2019. For older changelogs please consult the release tag on [GitHub](https://github.com/elixir-cldr/cldr_dates_times/tags)
## Breaking change
* Support Elixir 1.8 and later only since this package depends on [ex_cldr_calendars](https://hex.pm/packages/ex_cldr_calendars) which requires Elixir 1.8.
## Bug Fixes
* Fix references to `Cldr.get_current_locale/0` to the current `Cldr/get_locale/0`
* Fix dialyzer warnings
# Changelog for Cldr_Dates_Times v2.1.0
This is the changelog for Cldr_Dates_Times v2.1.0 released on June 16th, 2019. For older changelogs please consult the release tag on [GitHub](https://github.com/elixir-cldr/cldr_dates_times/tags)
## Enhancements
* All calling `Date`, `Time` and `DateTime` `to_string/3` as `to_string/1` omitting the backend and providing options. The backend will default to `Cldr.default_backend()`. An exception will be raised if there is no default backend.
* Updates to [ex_cldr_calendars 1.0](https://hex.pm/packages/ex_cldr_calendars/1.0.0) which includes `Cldr.Calendar.week_of_month/1`. The result corresponds to the `W` format which is now implemented as well.
# Changelog for Cldr_Dates_Times v2.0.2
This is the changelog for Cldr_Dates_Times v2.0.2 released on June 12th, 2019. For older changelogs please consult the release tag on [GitHub](https://github.com/elixir-cldr/cldr_dates_times/tags)
## Bug Fixes
* Resolve the actual number system before transliterating a date, time or datetime. Closes #9. Thanks to @ribanez7 for the report.
# Changelog for Cldr_Dates_Times v2.0.1
This is the changelog for Cldr_Dates_Times v2.0.1 released on June 9th, 2019. For older changelogs please consult the release tag on [GitHub](https://github.com/elixir-cldr/cldr_dates_times/tags)
## Bug Fixes
* Fixes a formatter code generation error when a format is a tuple form not a string form.
# Changelog for Cldr_Dates_Times v2.0.0
This is the changelog for Cldr_Dates_Times v2.0 released on June 9th, 2019. For older changelogs please consult the release tag on [GitHub](https://github.com/elixir-cldr/cldr_dates_times/tags)
This release depends on [ex_cldr_calendars](https://hex.pm/packages/ex_cldr_calendars) which provides the underlying calendar calculations as well as providing a set of additional calendars.
## Breaking Changes
* `ex_cldr_dates_times` requires a minimum Elixir version of 1.8. It depends on `Calendar` capabilities built into this and later release.
* `ex_cldr_dates_times` now depends upon [ex_cldr version 2.0](https://hex.pm/packages/ex_cldr/2.0.0). As a result it is a requirement that at least one backend module be configured as described in the [ex_cldr readme](https://hexdocs.pm/ex_cldr/2.0.0/readme.html#configuration).
* The public API is now based upon functions defined on a backend module. Therefore calls to functions such as `Cldr.DateTime.to_string/3` should be replaced with calls to `MyApp.Cldr.DateTime.to_string/3` (assuming your configured backend module is called `MyApp.Cldr`).
## Enhancements
* Correctly calculates `week_of_year`
* Supports `Calendar.ISO` and any calendar defined with `Cldr.Calendar` (see [ex_cldr_calendars](https://hex.pm/packages/ex_cldr_calendars))
## Known limitations
* Does not calculate `week_of_month`. If called will return `1` for all input values.
## Migration
`ex_cldr_dates_times` uses the configuration set for the dependency `ex_cldr`. See the documentation for [ex_cldr](https://hexdocs.pm/ex_cldr)
Unlike `ex_cldr_dates_times` version 1, version 2 requires one or more `backend` modules to host the functions that manage CLDR data. An example to get started is:
1. Create a backend module:
```elixir
defmodule MyApp.Cldr do
use Cldr,
locales: ["en", "fr", "ja"],
providers: [Cldr.Number, Cldr.Calendar, Cldr.DateTime]
end
```
2. Update `config.exs` configuration to specify this backend as the system default:
```elixir
config :ex_cldr,
default_locale: "en",
default_backend: MyApp.Cldr
```
3. Replace calls to `Date`. `Time` and `DateTime` functions `to_string/2` with calls to `to_string/3` where the second parameter is a backend module.
