+    - Require C11 compliant compiler.
     - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used

     - Added configure checks whether C++ compiler supports so called
       'designated initializers'.
+    - Added global backtraceAsString() function for debugging purposes
+      (POSIX systems only, no Windows implementation yet).
+    - Thread class: Added new methods pushCancelable(), popCancelable(), name(),

+    - configure: Always check for availability of pthread_testcancel() and use
