+- *nhm-tool*: refactor parsing of *ldd* output, previously it could fail in rare
+  cases when there were any not found libraries in the list.
+
 ### 0.6.0.0
 
 - *nhm-tool*: add command *plan* to print the build plan or its derivatives.
   Command *deps* is now a synonym for command *plan deps*.
 - *nhm-tool*: generate more secure *Makefile* with variables surrounded by
-  commas in shell parts.
+  double quotes in shell parts.
 
 ### 0.5.6.0
