-The next version of the Fortran standard after Fortran 2003 is currently
-being worked on by the Working Group 5 of Sub-Committee 22 of the Joint
-Technical Committee 1 of the International Organization for
-Standardization (ISO) and the International Electrotechnical Commission
-(IEC). This group is known as @uref{http://www.nag.co.uk/sc22wg5/, WG5}.
-The next revision of the Fortran standard is informally referred to as
-Fortran 2008, reflecting its planned release year. The GNU Fortran
-compiler has support for some of the new features in Fortran 2008. This
-support is based on the latest draft, available from
-@url{http://www.nag.co.uk/sc22wg5/}. However, as the final standard may
-differ from the drafts, no guarantee of backward compatibility can be
-made and you should only use it for experimental purposes.
+The latest version of the Fortran standard is ISO/IEC 1539-1:2010, informally
+known as Fortran 2008. The official version is available from International
+Organization for Standardization (ISO) or its national member organizations.
+The the final draft (FDIS) can be downloaded free of charge from
+@url{http://www.nag.co.uk/sc22wg5/links.html}. Fortran is developed by the
+Working Group 5 of Sub-Committee 22 of the Joint Technical Committee 1 of the
+International Organization for Standardization and the International
+Electrotechnical Commission (IEC). This group is known as
+@uref{http://www.nag.co.uk/sc22wg5/, WG5}.
+
+The GNU Fortran supports several of the new features of Fortran 2008; the
+@uref{http://gcc.gnu.org/wiki/Fortran2008Status, wiki} has some information
+about the current Fortran 2008 implementation status. In particular, the
+following is implemented.
+
+@itemize
+@item The @code{-std=f2008} option and support for the file extensions
+@code{.f2008} and @code{.F2008}.
+
+@item The @code{OPEN} statement now supports the @code{NEWUNIT=} option,
+which returns a unique file unit, thus preventing inadvertent use of the
+same unit in different parts of the program.
+
+@item The @code{g0} format descriptor and unlimited format items.
+
+@item The mathematical intrinsics @code{ASINH}, @code{ACOSH}, @code{ATANH},
+@code{ERF}, @code{ERFC}, @code{GAMMA}, @code{LOG_GAMMA}, @code{BESSEL_J0},
+@code{BESSEL_J1}, @code{BESSEL_JN}, @code{BESSEL_Y0}, @code{BESSEL_Y1},
+@code{BESSEL_YN}, @code{HYPOT}, @code{NORM2}, and @code{ERFC_SCALED}.
+
+@item Using complex arguments with @code{TAN}, @code{SINH}, @code{COSH},
+@code{TANH}, @code{ASIN}, @code{ACOS}, and @code{ATAN} is now possible;
+@code{ATAN}(@var{Y},@var{X}) is now an alias for @code{ATAN2}(@var{Y},@var{X}).
+
+@item Support of the @code{PARITY} intrinsic functions.
+
+@item The following bit intrinsics: @code{LEADZ} and @code{TRAILZ} for
+counting the number of leading and trailing zero bits, @code{POPCNT} and
+@code{POPPAR} for counting the number of one bits and returning the parity;
+@code{BGE}, @code{BGT}, @code{BLE}, and @code{BLT} for bitwise comparisons;
+@code{DSHIFTL} and @code{DSHIFTR} for combined left and right shifts,
+@code{MASKL} and @code{MASKR} for simple left and right justified masks,
+@code{MERGE_BITS} for a bitwise merge using a mask, @code{SHIFTA},
+@code{SHIFTL} and @code{SHIFTR} for shift operations, and the
+transformational bit intrinsics @code{IALL}, @code{IANY} and @code{IPARITY}.
+
+@item Support of the @code{EXECUTE_COMMAND_LINE} intrinsic subroutine.
+
+@item Support for the @code{STORAGE_SIZE} intrinsic inquiry function.
+
+@item The @code{INT@{8,16,32@}} and @code{REAL@{32,64,128@}} kind type
+parameters of the intrinsic module @code{ISO_FORTRAN_ENV}.
+
+@item Experimental coarray support (for one image only), use the
+@code{-fcoarray=single} flag to enable it.
+
+@item The @code{BLOCK} construct is supported.
+
+@item The @code{STOP} and the new @code{ERROR STOP} statements now
+support all constant expressions.
+
+@item Support for the @code{CONTIGUOUS} attribute.
+
+@item Support for @code{ALLOCATE} with @code{MOLD}.
+
+@item Support for the @code{IMPURE} attribute for procedures, which
+allows for @code{ELEMENTAL} procedures without the restrictions of
+@code{PURE}.
+
+@item Null pointers (including @code{NULL()}) and not-allocated variables
+can be used as actual argument to optional non-pointer, non-allocatable
+dummy arguments, denoting an absent argument.
+@item Non-pointer variables with @code{TARGET} attribute can be used as
+actual argument to @code{POINTER} dummies with @code{INTENT(IN)}.
+
+@item Pointers including procedure pointers and those in a derived
+type (pointer components) can now be initialized by a target instead
+of only by @code{NULL}.
+
+@item The @code{EXIT} statement (with construct-name) can be now be
+used to leave not only the @code{DO} but also the @code{ASSOCIATE},
+@code{BLOCK}, @code{IF}, @code{SELECT CASE} and @code{SELECT TYPE}
+constructs.
+
+@item Internal procedures can now be used as actual argument.
+
+@item Minor features: obsolesce diagnostics for @code{ENTRY} with
+@code{-std=f2008}; a line may start with a semicolon; for internal
+and module procedures @code{END} can be used instead of
+@code{END SUBROUTINE} and @code{END FUNCTION}; @code{SELECTED_REAL_KIND}
+now also takes a @code{RADIX} argument; intrinsic types are supported
+for @code{TYPE}(@var{intrinsic-type-spec}); multiple type-bound procedures
+can be declared in a single @code{PROCEDURE} statement; implied-shape
+arrays are supported for named constants (@code{PARAMETER}).
