-	* don't crash if MODULEPATH starts or ends with a colon 
-	* add overlay info to output of sub-command 'search'
+    * The shell`s init file is sourced, when Pmodules is loaded as module.

 * **build-system**
   * *User visible changes*
-    * modbuild is now defined as shell function analog to module()
-	* modbuild can be called without specifying a build-script,
-	  if a build-script exist in the current working directory
-	* abort build on error
-	* with option `--overlay`
-	  - an overlay can be set if legacy variants files are used
-	  - the overlay in the YAML variants file can overriden
-  * *Internal changes and fixes*
-	* bugfix in setting PATH
-	* requires bash 5 or later
+    * The command 'modbuild' is now defined as shell function analog to
+      the 'module' command. The main reason to introduce this function
+      is due to the fact that Bash version 5 or newer is now required
+      by 'modbuild'. The function 'modbuild' load Bash 5.x as module
+      before calling the modbuild-script. If you want to use the script
+      directly, a Bash binary with version 5.x must be in PATH.
+    * If a build-script is in the current working directory,
+      'modbuild' can now be called without specifying the build-script.
+    * In case of an error in a build-step the build process did not 
+      abort as it should. This has been fixed.
+    * The option `--overlay` can now be used
+	  - to define an overlay if legacy variants files are used
+	  - to override the overlay in a YAML variants file.
+    * The new keyword `with` has been introduced in YAML variants file
+      to specified hierarchical dependencies.
