New/Changed Features

  • Added dman
  • Add support for Mac OS X 10.7 Lion
  • Add protection to json output
  • Add SSE4.1 and SSE4.2 assembly instructions
  • Bugzilla 4375: Require explicit braces when 'else' is ambiguous
  • std.algorithm.copy now specializes on arrays for 10-80x improved performance.
  • std.path has been rewritten from scratch and has a completely new API.
  • std.utf.toUTFz allows you to get a zero-terminated string of any character type and of any type of mutability.
  • Added symlink and readLink to std.file for Posix systems.
  • Values for GDC and LDC were added to std.compiler.Vendor.
  • Added functions to std.bitswap for generically handling swapping endianness.
  • Added std.parallelism.TaskPool.workerIndex.
  • Added buffer recycling overload of std.parallelism.asyncBuf
  • std.math.tgamma, lgamma, erf, and erfc are now deprecated. The equivalent functions in std.mathspecial should be used instead.
  • The names of the values of std.mmfile.Mode, std.system.Endian, std.traits.FunctionAttributes, std.traits.ParameterStorageClass, and std.traits.Variadic were changed to match Phobos' naming conventions.
  • std.range: Added indexed and chunks
  • std.string.translate has been updated to work with unicode. As a result, its signature has been changed. The old version and std.string.maketrans have been scheduled for deprecation.
  • std.string.tr has been updated so that it works with any string type.
  • std.conv.parse works for associative array and static array
  • std.format: Improvement of formatValue and unformatValue. They now works for associative array, consider element escaping, and treat range format spec more properly.
  • std.complex: added sin(), cos(), sqrt()
  • md5: 1.4X speedup

Druntime Bugs Fixed

  • Bugzilla 5967: Mangling of ArgClose for variadic function is swapped
