ICU 77 Released
Markus Scherer
Dear friends and users of ICU,
We are pleased to announce the release of Unicode® ICU 77. It updates to CLDR 47 (beta blog) locale data with new locales, and various additions and corrections.
ICU 77 is mostly focused on bug fixes, segmentation conformance, and other refinements.
The Java technology preview implementation of the CLDR MessageFormat 2.0 specification has been updated to incorporate the CLDR 46.1 spec plus most but not all of the CLDR 47 changes.
The C++ technology preview implementation of MessageFormat 2.0 is not yet quite up to date with CLDR 46.1.
Please note that for ICU 78 (2025-oct) we are planning to (a) upgrade from Java 8 to Java 11, and (b) remove the ICU4J Locale Service Provider. See the ICU 77 page for details.
Best regards,
Markus Scherer for the ICU Project

Attention: Future Changes
Beginning with ICU 78 (2025-oct):
- We want to move the minimum required Java version from Java 8 to Java 11. This is a significant, useful update in terms of the Java language and standard library, and simplifies ICU tooling which currently uses a mix of Java 8 and Java 11. Note that supports at least Java 11 since late 2023.
See where you can provide comments.

Attention: Future Changes
Beginning with ICU 78 (2025-oct):
- We are planning to remove the (). It is much less useful than when we added it, has very low usage, needs work for newer Java versions, and complicates ICU4J development.
- See where you can provide comments.
Best regards,
