+- Check null pointer return from memory/resource allocation functions (nullPointerOutOfMemory,
+  nullPointerArithmeticOutOfMemory, nullPointerOutOfResources, ctunullpointerOutOfMemory,
+  ctunullpointerOutOfResources).
 
 Changed interface:
--Added `reduced` check level. It can be activated with `--check-level=reduced`. You get faster analysis
-but some fewer results. The motivation is to be able to make analysis time "acceptable" for direct usage.
-
--Added `--report-type` option. Enables printing of guidelines and classifications for several coding
-standards in place of the regular error identifiers and severities.
