 o Fixed bug in VRF driver when one client connection is closed and another
   opened. 
 
 o Fixed severe problems with VRF driver and selection expressions for string
   fields. 

 o Fixed severe problem composing area polygons from non-tiled VRF datastores
   (such as VMAP0 rference layer). 

 o Fixed additional memory leaks. 

 o Improvements in README for how to build on Unix and windows.


3.1.3
=====

 o Fixed major leak in VPF driver. 
 
 o Support TOC files without FSDEVG field.

 o Fixed rounding error in computing "nbfeature" in RPF driver (rounding issue)

 o Assorted other minor bug fixes, and memory leak cleanup.


3.1.2
=====

 o Minor fixes for MacOS 10.3 support (older versions of MacOS won't work 
   easily)

 o Fixed minor memory leaks in core.

 o Fixed major file handle leak in ADRG driver. 

 o Fixed bugs in VPF driver, especially for VITD datasets.


3.1.1
=====

 o Upgraded to ZLIB 1.1.4 to avoid buffer overflow security risk in zlib 1.1.3.

 o Various bugs fixed, and improvements to ogdi_info, and ogdi_import 
   utilities.

 o Fixed problems in cln_CalcCtlPoints() with very small regions, equivelent 
   to one pixel of data.  Sometimes produced a degenerate transformation.

 o Added OGDI_VERSION and OGDI_RELEASEDATE macros in ecs_util.h.


3.1.0
=====

Essentially the same as 3.1Beta1.


3.1Beta1
========

 o Implement support for XML Capabilities (as per Proposal 6: Capabilities
   Metadata).  This includes:

     - Added support for reaturning correct capabilities to adrg, dted, rpf
       and vpf drivers. 

     - Added support for parsing capabilities documents, in libogdi utilizing
       Expat (incorporated into the source tree under devdir/external). 

     - Added public client side API for accessing capabilities and version
       information (cln_GetLayerCapabilities(), cln_GetVersion()). 

 o Upgraded VPF driver to support brackets in query expression.  Implemented
   using generic "restricted_where" processor (swq.c).

 o Upgraded ADRG, RPF and DTED drivers to support Image (as well as Matrix)
   family support based on updates supplied by DND. 

 o Added contributed GDAL raster driver as contrib/gdal.

 o Updated zlib in external/zlib to 1.1.3.

 o Embed version number in OGDI shared libraries (eg. libogdi31.so).


3.1Alpha
========

 o Incorporated contrib/ogdi_import, and contrib/ogdi_info sample applications.

 o Updated build system to include configure script, install target, and 
   various cleanups and simplifications.  RPCGEN is no longer run by default.
   External versions of libz and PROJ.4 can be utilized.

 o Updated licenses within source code to reflect the redistributable nature
   of code written by LAS on contract to DND.  

 o Variety of bug fixes, primarily to drivers. 

 o Remove warnings during build from core code.
