ICU4X 1.0 Beta

We are pleased to announce a 1.0 Beta release of ICU4X!

What does this mean?

• We anticipate no major changes to the Rust API between now and the 1.0 final release, so you can use 1.0 Beta and later upgrade to 1.0 with minimal changes required to your code.
• The C++ and TypeScript APIs do not yet have full coverage, but we intend to focus on this over the next few weeks.
• Most changes between now and 1.0 will be documentation, tutorials, and FFI coverage.

Please try out ICU4X 1.0 Beta and leave feedback!

Stay tuned over the coming weeks for more information in anticipation of our 1.0 release.
