+
+* Matt T. Proud contributed documentation fix to call Go programming
+  language by it's true name instead of golang.
+
+* Robert Scott contributed debugallocator feature to use readable

+
+* User stdpain contributed fix for cmake detection of libunwind.
+
+* Natale Patriciello contributed fix for OSX Monterey support.
+
+* Volodymyr Nikolaichuk contributed support for returning memory back
+  to OS by using mmap with MAP_FIXED and PROT_NONE. It is off by
+  default and enabled by preprocessor define:
