 ## Upgrading
 
+* The CLI tool is moved to dedicated folder.
+
 <!-- Here goes notes on how to upgrade from previous versions, including deprecations and what they should be replaced with -->
 
 ## New Features
 
+* Support data requests for multiple component IDs from command line.
+* Support for passing formula strings as a `cid` argument from the command line.
+
 <!-- Here goes the main new features and examples or instructions on how to use them -->
