Note that the GSHHS polygons have not changed (still at version 2.0), but we had to update the derived netcdf repackaging used by <A NAME="tex2html199" HREF="http://gmt.soest.hawaii.edu"><B>GMT</B></A> to 2.0.1. However, some enhancements were added as well, most significantly support for the polyconic projection (<B>-JPoly</B>), experimental support for grid and image imports via GDAL (requires -enable-gdal during configure and properly installed GDAL libraries and include files), and allowing <B>-JX</B><I>width/height</I> to recompute a <I>height</I> given as zero based on the <I>width</I> (or vice versa) and the aspect ratio of the region. <P> Here is the list of bug corrections: <DL> <DT><STRONG><A NAME="tex2html200" HREF="../man/configure.ac.html"><I><B>configure.ac</B></I></A><A NAME="2918"></A></STRONG></DT> <DD>: Now use -enable-flock to enable file locking, instead of -disable-flock to disable if. Use -enable-64 to force 64-bit compilation, use -disable-64 to force 32-bit compilation; otherwise use default.
