 # Notable Changes in StatET RJ
 
+## RJ 4.2.0 ~ StatET 4.2.0
+
+### Setup
+
+  * The `AppEnvironment` is enhanced and provides bundle resolution now. `RJContext` uses the
+    AppEnvironment for bundle resolution by default. Applications need to be adapted.
+    
+    The bundle `org.eclipse.statet.jcommons.util` provides tools for bundle resolution in different
+    types of application.
+    Automatic setup of the application environment is supported for
+      - Applications based on Eclipse Platform: fully automated
+      - Common "simple" Java applications: use CommonsRuntime.check with `autoInit= true`
+    
+    (Bug 561121)
