+- update to 1.66:
+  * new checks added:
+    - Compare pointer with '\0'
+    - Assigning boolean expression to floating point variables
+  * Improvements:
+    - Much improved AST
+    - Much improved ValueFlow analysis
+    - ValueFlow and AST now used by much more checks, improving
+      checking accuracy and performance
+    - Checking for self assignment now supports more complex
+      expressions
+    - Returning references to literals or references to calculation 
+      results is detected
+    - Enhanced support for commutative operators in duplicate 
+      expression checking
+    - Improved template/enum parsing
+    - Much improved htmlreport
+    - Definition of POD types in .cfg files
+    - Definition of minsize for buffer arguments in .cfg files 
+      for buffer overflow checking
+    - Fixed handling of #error: Do not report them if -f and -D 
+      are used together
+    - New .cfg file for AVR platform
+    - Generate xml dump of AST/ValueFlow/SymbolDatabase/TokenList 
+      if --dump is given
+    - Improved performance in several cases
