 ## Implementations
 
-- Java: [`com.ibm.icu.message2`](https://unicode-org.github.io/icu-docs/apidoc/dev/icu4j/index.html?com/ibm/icu/message2/package-summary.html), part of ICU 75, is a _tech preview_ implementation of the MessageFormat 2 syntax, together with a formatting API. See the [ICU User Guide](https://unicode-org.github.io/icu/userguide/format_parse/messages/mf2.html) for examples and a quickstart guide.

-- JavaScript: [`messageformat`](https://github.com/messageformat/messageformat/tree/master/packages/mf2-messageformat) 4.0 implements the MessageFormat 2 syntax, together with a polyfill of the runtime API proposed for ECMA-402.
