I am pleased to announce the release of PROJ 4.8.0.  This is a
major new feature release and collects all the work done since
the PROJ 4.7.0 release in September 2009.  The NEWS file includes
these major items:

 * Added the Natural Earth projection.
 * Added HEALPIX, rHEALPIX and Icosahedral Snyder Equal Area projections.
 * nad2bin now produces "CTable2" format grid shift files by default which
   are platform independent.
 * nad2nad removed, use cs2cs for datum shift operations.
 * projects.h no longer installed as a public include file.  Please try to
    only use proj_api.h.
 * Add pj_get_spheroid_defn() accessor.
 * Added an alternate version of pj_init() that takes a projCtx (execution
    context) structure to address multithreading issues with error management
    and to provide a support for application hookable error reporting and
 * Upgrade to EPSG 7.9.  Some changes in ideal datum selection.
 * JNI bindings reworked, org.proj4.Projections deprecated in favor of
 * Added preliminary vertical datum support.
 * Fix various multithreading issues, particular in datum grid handling code.
 * Added support for the +axis= option for alternate axis orientations as
    part of a coordinate system (used for TM South Orientated support).
 * +proj=omerc implementatioin replaced with code from libproj4.  +rot_conv
    flag no longer works, and some coordinate systems (ie. Malaysian) will
    need to use +gamma instead.  "epsg" init file updated accordingly.
