CHANGELOG.md

@@ -3,8 +3,9 @@
 This changelog summarizes major changes between GraalVM versions of the Python
 language runtime. The main focus is on user-observable behavior of the engine.
 
-## Version 24.2.0
+## Version 24.1.1
 * Updated developer metadata of Maven artifacts.
+* Added gradle plugin for polyglot embedding of Python packages into Java.
 
 ## Version 24.1.0
 * GraalPy is now considered stable for pure Python workloads. While many workloads involving native extension modules work, we continue to consider them experimental. You can use the command-line option `--python.WarnExperimentalFeatures` to enable warnings for such modules at runtime. In Java embeddings the warnings are enabled by default and you can suppress them by setting the context option 'python.WarnExperimentalFeatures' to 'false'.
