+Version 6.2.3
+=============
+
+Improvements and bug fixes:
+---------------------------
+- New setting "ignore_flags":
+  You can now set up a list of patterns to ignore flags you don't want to be
+  passed to clang. This is useful, when there is, say, gcc-specific header in
+  the include flags and you want to get rid of it as it causes compilation
+  issues for clang.
