Across the globe, people are coming online with smaller and more varied devices including smartphones, smartwatches, and gadgets. An offshoot of the International Components for Unicode (ICU) Technical Committee, the ICU4X Committee, is responsible for enabling these next-generation devices to communicate with their users in thousands of languages. Written in Rust, ICU4X brings lightweight, modular, and secure internationalization libraries to low-resource devices and many programming languages.
The ICU4X-TC is happy to now announce the release of ICU4X 2.0 Beta 1. Learn more about it in our UTW 2024 presentation: 2024 ICU4X 2.0: Next Level i18n
This release includes a rewritten datetime component, type-safe preferences in all constructors, CLDR 46 and Unicode 16 data, new experimental duration and unit formatting components, an all-new WebAssembly demo, and improvements to many other components including locale tailoring in segmenter, algorithmic plural selection, and IXDTF parsing for zoned datetimes.
This release includes breaking changes. The most common you will encounter include:
All constructors take a preference bag by value instead of a `&DataLocale`.
Many functions had subtle renames, such as `try_from_bytes` becoming `try_from_utf8`.
The datetime component was rewritten, and call sites will need to be migrated.
Refer to the latest documentation for more information. Please also ask questions on GitHub:

This is a beta release, meaning that the team expects this to be mostly compatible with the upcoming 2.0 final release, but there is still room to make changes. Please send feedback by creating an issue or discussion on GitHub.
