  > - replace uint buffer lengths with size_t
  > - add line-by-line opApply to Stream and InputStream (due to Regan Heath)
  >   int opApply(int delegate(inout char[] line) dg)
  >   int opApply(int delegate(inout ulong n, inout char[] line) dg)
  >   int opApply(int delegate(inout wchar[] line) dg)
  >   int opApply(int delegate(inout ulong n, inout wchar[] line) dg)
  > - move readable/writeable/seekable tests from contracts to the body since phobos is compiled in release mode and users can easily try to write to an unwritable stream
  > - return "this" from writef and writefln to allow chaining (eg flush)
  > - fix TArrayStream read/write to check for "eof" (Derick Eddington)
  > - make SliceStream preserve the source buffer position if seekable and pay attention to isOpen (Derick)
  > - implement available() for more stream types (Derick)
  > - copyFrom bug fixes and position preserving if seekable (Derick)
  > - move the initialization of the BOMs to the initializer instead of the module constructor.
  > - make isopen protected (from private) so that subclasses can see it.
  > - more unittest (Derick and Ben)
  > - fix File.size() bug on Windows
  > - fix File.open() error message to say "Cannot open or create file"

### What's New for D 0.101

Aug 30, 2004

#### New/Changed Features

- Added Ben Hinkle's improvements to std.stream. Ben writes: "I've attached a modified version of std.stream and phobos.html that include the bug fixes and behavior changes outlined in the newsgroup post yesterday. The bug fixes are almost entirely backwards compatible. The biggest difference is the change that opening a file on Windows with FileMode.In errors when the file doesn't exist. That makes it the same behavior as Linux and it just seems to make sense. I also did things like added writef and changed the Error classes to Exception."
- Kris pointed out that version identifiers have global effect, and are dependent on which order modules are imported. This is clearly wrong. Now, only version and debug definitions on the command line have global effect. Others only influence the module they are declared in. Furthermore, version and debug definitions can only be done at module scope.

### What's New for D 0.65

### What's New for D 0.58

Mar 3, 2003

- Added covariant function return types.
- Fixed several bugs in nested functions, template argument deduction, access protections, constant folding, etc.

### What's New for D 0.57

Feb 25, 2003

- Added keyword function and new function pointer syntax analogous to the way the delegate declaration syntax works.
- Added function literals.
- Added nested functions.

- Fixed struct/class definitions nested within functions.

Many thanks to Burton Radons for his help with this.

### What's New for D 0.56

Feb 20, 2003

- Fixed a couple bad bugs with template typedefs and arrays.

### What's New for D 0.55

Feb 17, 2003

- Added several new math functions to math.d.
- Changed behavior of new expressions to match change in array declaration order:

      	char[][] foo;
      	foo = new char[][45];	// new, correct way to allocate array of 45 strings
      	//foo = new char[45][];	// old, now wrong, way

- Fixed some problems with error recovery.
- The module name is now in its own scope enclosing the scope of the contents of the module (before it was simply inaccessible).

### What's New for D 0.54

Feb 14, 2003

- Fixed some parsing problems with template instances.
- Introduced new types cfloat, cdouble, ifloat, idouble.
- Introduced new constant types ifloat, idouble.
- Renamed extended to real.
- Renamed imaginary to ireal.
- Renamed complex to creal.
- Reversed order of array declarations when they appear to the left of the identifier being declared. Postfix array declaration syntax remains the same (and equivalent to C).

      	int[3][4] a;	// a is 4 arrays of 3 arrays of ints
      	int b[4][3];	// b is 4 arrays of 3 arrays of ints

These changes have been needed for a while, and it's time to put them in before D gets too constrained by legacy code. Fortunately, using grep and global/search/replace can easily take care of the type renames. The array declaration issue can be fixed by grepping for "][", and then manually fixing each.

### What's New for D 0.53

- Fixed several problems with templates.
- Added #line pragma support.
- D can now accept source files in various UTF formats.

### What's New for D 0.50

Nov 20, 2002

- To convert to type bit now requires an explicit cast, rather than implicit. The conversion `(cast(bit)i)` is now performed as `(i?true:false)`.
- Added library functions string.toString().
- Fixed many template bugs.
- Changed implicit conversion rules for integral types; implicit conversions are not allowed if the value would change. For example:

      	byte  b = 0x10;		// ok
      	ubyte c = 0x100;	// error
      	byte  d = 0x80;		// error
      	ubyte e = 0x80;		// ok
