Fortran 2003).</li>
<li>Support for the Fortran 2003 streaming IO extension has been
added.</li>
+ <li>The GNU Fortran compiler now uses 4-byte record markers by default
+ for unformatted files to be compatible with g77 and most other compilers.
+ The implementation allows for records greater than 2 GB and compatible
+ with several other compilers. Older versions of gfortran used by default
+ 8-byte record markers (on most systems). In order to change length of
+ the record markers, e.g. to read unformatted files created by older
+ gfortran versions, the <code>
+ <a href="http://gcc.gnu.org/onlinedocs/gfortran/Runtime-Options.html";
+ >-frecord-marker=8</a></code> option can be used.</li>
