released Jan 27, 2016

#### Language Changes

#### Library Changes

1. The package std.experimental.ndslice was added. It is also available as part of the Mir library.
2. The core.sys.windows package has been greatly expanded.
3. TypeInfo.init has been renamed to TypeInfo.initializer.
4. std.json encodes string control characters.
5. Default LogLevel of FileLogger was changed to LogLevel.all.
6. Access to the internal ptr and len fields of BitArray was deprecated.

List of all bug fixes and enhancements in D 2.070.0.

#### Language Changes

1. Add syntactic support to make an alias to a function literal.

   Example:

       alias less1 = (a, b) => a < b;
       alias less2 = (a, b) => a > b;

       import std.algorithm : sort, equal;

       int[] arr = [4, 1, 3, 2];
       assert(equal(sort!less1(arr), [1, 2, 3, 4]));
       assert(equal(sort!less2(arr), [4, 3, 2, 1]));

#### Library Changes

1. The core.sys.windows package has been greatly expanded.

   The core.sys.windows package now contains a considerably more comprehensive set of Windows API bindings. The package has been adapted from Stewart Gordon's bindings, which were originally adapted from the MinGW project.

2. TypeInfo.init has been renamed to TypeInfo.initializer.

   The method TypeInfo.init has been renamed to TypeInfo.initializer to resolve a name clash with the type property init.

   An alias with the old name was added and will be deprecated over the next releases.

3. std.json encodes string control characters.

   Instead of throwing a JSONException, toJSON encodes now the control characters of a string.

       assert(toJSON(JSONValue("foo\u007fbar")) == `"foo\u007Fbar"`);
