+### Attention: Future Changes
+
+Beginning with ICU 78 (2025-oct):
+
+1. 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 [Android desugaring](https://developer.android.com/studio/write/java11-default-support-table)
+   supports at least Java 11 since late 2023.\
+   See [ICU-23072](https://unicode-org.atlassian.net/browse/ICU-23072)
+   where you can provide comments.
+2. We are planning to remove the
+   [ICU4J Locale Service Provider](../userguide/icu4j/locale-service-provider.md)
+   ([Maven: com.ibm.icu / icu4j-localespi / version 76.1](https://mvnrepository.com/artifact/com.ibm.icu/icu4j-localespi/76.1)).
+   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 [ICU-23071](https://unicode-org.atlassian.net/browse/ICU-23071)
+   where you can provide comments.
+
