Cldr Units version 3.5.0-rc.1

Overview

In this release the Cldr.Unit.to_string/{1, 2, 3} function has been rewritten and the concrete impementation is now in Cldr.Unit.Format. The primary reasons for rewriting are:

1. Improves performance by 20% over the old implementation.
2. Supports grammatical case and grammatical gender. These allow for better sentence formation in a localised fashion. Only are few locales have the required data for now (for example, fr and de) however more locales will have data in upcoming CLDR releases.

Note that full testing of grammatical case and grammatical gender variations is not yet complete.

Soft Deprecation

• The function Cldr.Unit.to_iolist/{1, 2, 3} is soft deprecated. It is still available and no deprecation warning is emitted. It will however be removed from the public API in a future release. This function is primarily used to support implementation of Cldr.Unit.to_string/3

• As of this release, argument checking in Cldr.Unit.to_iolist/3 is less rigorous in order to avoid the relatively expensive argument normalization process happening twice (once in Cldr.Unit.to_string/3 and then again in Cldr.Unit.to_iolist/3).

Bug Fixes

• The new string formatter correctly assembles units with an SI prefix (ie millimeter) in languages such as German where the noun is capitalized.
