-Break backward compatibility
--------------
-* change the type of Xbyak::Error from enum to a class.
-** get the enum value by cast to int.
-* An (old) Reg32e class will split (new) Reg32e class and (new) RegExp.
-(new) Reg32e class is Reg32 or Reg64.
-(new) RegExp class is to deal with 'Reg32e + Reg32e * scale + disp'.
-Please rename Reg32e as RegExp if you use (old) Reg32e as RegExp.
-
 New Feature
 -------------
 
-* Use MmapAllocator if XBYAK_USE_MMAP_ALLOCATOR.
-Default allocator calls posix_memalign on Linux, then mprotect recudes map count.
-The max value is written in  ```/proc/sys/vm/max_map_count```.
-The max number of instances of ```Xbyak::CodeGenerator``` is limited to the value.
-See ```test/mprotect_test.cpp```.
-Use MmapAllocator if you want to avoid the restriction(This behavior may be default in the feature).
-
-
-* AutoGrow mode is a mode that Xbyak grows memory automatically if necessary.
-Call ready() before calling getCode() to calc address of jmp.
-```
-    struct Code : Xbyak::CodeGenerator {
-      Code()
-        : Xbyak::CodeGenerator(<default memory size>, Xbyak::AutoGrow)
-      {
-         ...
-      }
-    };
-    Code c;
-    c.ready(); // Don't forget to call this function
-```
->Don't use the address returned by getCurr() before calling ready().
->It may be invalid address.
->RESTRICTION : rip addressing is not supported in AutoGrow
+Add support for AVX-512 instruction set.
