 ==Graphical environment==
-* 
+* Added code completion support for once classes
+* Improved the '''Add Library''' implementation by allowing to add "redirection" ecf files, and fixed the '''Add Cluster''' functionalities in recursive cluster.
+* Fixed an harmless exception when first inserting Unicode symbol using the "Insert Symbol" dialog on Windows.
 
 ==Compiler==
-* 
+* New platforms:  macosx-armv6 (M1, M2 support) and linux-arm64.
+* Reviewed and updated generated C code to fix potential execution issues due to "clang" C compiler optimizations (especially on ARM architecture).
+* Fixed the compilation of once class without any creation procedures.
 
 ==Tools==
-* 
+* It is now possible to use the "emdc.exe" .Net md consumer, as an alternative to the COM md consumer from EiffelStudio, as a first step toward supporting .Net on non Windows platform.
+
 ==Libraries==
