+1.0.2 -> 1.1.0
+---------------
+* Use inline assembler for gcc on ix86 as a default.
+* Add DL::Importable module (defined in "dl/import.rb").
+
+1.0.1 -> 1.0.2
+--------------
+* Fix an installation problem, thanks to Nakada.
+* Handle#to_i, to_ptr is added.
+* lib/dl/win32.rb is added for Win32API compatibility.
+
+1.0 -> 1.0.1
+-------------
+* Fix PtrData#to_s.
+* Add PtrData#to_str(size).
+
+0.9 -> 1.0 (stable)
+-------------------
+* PtrData object keeps size data if possible.
+* PtrData#size is added.
+* LoadLibary(), FreeLibrary() and GetProcAddress() are used on
+  windows instead of dlopen(),dlclose() and dlsym().
+
+0.8.1 -> 0.9
+------------
+* You can use inline assembler to constracting the function calls by
+  building the library using --with-asm options for extconf.rb.
+  But now this can work with GNU assembler on i386 machines. If you try
+  this mechanism, you can get rid of the limit of number of parameters.
+
+0.8 -> 0.8.1
+-------------
+* rb_dlsym_call() calls xmalloc() or dlmalloc() instread of
+  alloca() because of portability.
+
+* 'h2rb' get to parse the enumeration type.
+
+0.7.1 -> 0.8
+-------------
+* If <type> of Symbol.new(addr, name = nil, type = nil) is nil,
+  it returns a DataPtr object.
+
+* PtrData#[] returns the memory image, and PtrData#[]= is used
+  to copy the memory image to specified area.
+
+* Handle#sym(symbol_name) returns a PtrData object, and
+  Handle#sym(symbol_name, type_spec) returns a Symbol object.
+
+* We can use the number following a type specifier to represent the
+  length of an array. For example, if you'd like to represent the
+  following structure, we use 'C1024I' when using PtrData#struct! or
+  PtrData#union!.
+
+    struct {
+      char name[1024];
+      int  age;
+    }
+
+0.6 -> 0.7
+-----------
+* type `ANY_FUNC' is removed, it is because the method for
+  calling the function obtained by dlsym() was changed.
+
+* `char', `short' and `float' types are supported, if you'd
+  like to use those type exactly and run extconf.rb with the
+  option `--with-type-{char,short,float}'.
+
+* `DL.sizeof(type)' returns the size of the <type> with the
+  alignment. so `DL.sizeof("C") + DL.sizeof("L")' is not equal
+  to `DL.sizeof("CL")'. it is assumed that the latter returns
+  the enough size for the following structure:
+    struct foo { char x; long y; }
+  but it may not equal to `sizeof(struct foo)' of C.
+
+* new methods:
+  - PtrData#define_data_type
+  - PtrData#struct!
+  - PtrData#union!
+  - PtrData#data_type
+  - PtrData#[]
+  - PtrData#[]=
+  - Symbol.new
+
+0.5 -> 0.6
+-----------
+* DL.set_callback is changed.
+  - set_callback(type,num,proc)   [old style]
+  - set_callback(type,num){...}   [new style]
+
+* the handle object don't call dlclose() at the time of GC.
+  if you need to call dlclose(), use Handle#enable_close.
+
+* new methods:
+  - PtrData#{+,-}
+  - PtrData#{+@,-@} (= PtrData#{ptr,ref})
+  - DL.malloc
+  - DL.strdup
+  - MemorySpace.each
+
+* some memory leaks are fixed.
+
+0.4 -> 0.5
+----------
+* new methods:
+  - DL.dlopen (= DL::Handle.new)
+  - PtrData#ref
+  - PtrData#==
+  - PtrData#eql?
+  - String#to_ptr
+  - Handle#enable_close
+  - Handle#disable_close
+
+* PtrData#ptr returns the pointed value (*ptr).
+
+* PtrData#ref returns the reference (&ptr).
+  `ptr.ref.ptr == ptr' must be true.
+
+(experiment)
+* the callback function is supported.
+
+* new methods:
+  - DL.set_callback
+  - DL.get_callback
+
+
+0.3 -> 0.4
+----------
+* Symbol#call supports the mechanism for converting any object
+  to PtrData object automatically using 'to_ptr' method, if the
+  argument type is 'P' or 'p'.
+
+* new methods are added.
+  - Array#to_ptr
+  - IO#to_ptr
+  - Symbol#to_ptr
+  - Symbol#[]
+
+* new constant is added.
+  - DL::FREE is a symbol object for representing the function 'free'.
+
+* the specification of PtrData#free was changed.
+
+* new internal functions are added.
+  - rb_dlptr2cptr()
+  - rb_dlsym2csym()
+  - rb_dlsym_new()
+
+* 'dl.h' is new file.
+
+* 'extconf.rb' and 'depend' ware modified so that we can build
+  the library in a directory except 'srcdir' (by N. Nakada).
+
+* (experimental) 'h2rb' is a new script which converts C header
+  files into ruby scripts.
+
+0.2 -> 0.3
+----------
+* many useful functions ware added (by Akinori Musha).
+
+* the type of 'long' was supported (by Akinori Musha).
+
+* some methods of the PtrData ware added for handling pointer data.
+
+* bug fix for mutable int and long.
+
+* the type of array was supported.
