+- update to 2.6.2:
+  * New checks in core cppcheck:
+    * missing return in function
+    * writing overlapping data, detect undefined behavior
+    * compared value is out of possible type range
+    * Copy elision optimization can't be applied for return std::move(local)
+    * file can not be opened for read and write access at the same
+      time on different streams
+  * Various improvements
