Import and export of +CRS objects from and into PROJ strings is also supported. This functionality +was previously available in the GDAL software library (except WKT2 support +which is a new feature), and is now an integral part of PROJ. + +A unified database of geodetic objects, coordinate reference systems and their +metadata, and coordinate operations between those CRS is now available in a +SQLite3 database file, proj.db. This includes definitions imported from the +IOGP EPSG dataset (v9.6.0 release), the IGNF (French national mapping agency) +geodetic registry and the ESRI projection engine database. PROJ is now the +reference software in the "OSGeo C stack" for this CRS and coordinate operation +database, whereas previously this functionality was spread over PROJ, GDAL and +libgeotiff, and used CSV or other adhoc text-based formats. + +Late-binding coordinate operation capabilities, that takes metadata such as +area of use and accuracy into account, has been added. This can avoid in a +number of situations the past requirement of using WGS84 as a pivot system, +which could cause unneeded accuracy loss, or was not doable at all sometimes +when transformation to WGS84 was not available. Those late-binding capabilities +are now used by the proj_create_crs_to_crs() function and the cs2cs utility. + +A new command line utility, projinfo, has been added to query information about +a geodetic object of the database, import and export geodetic objects from/into +WKT and PROJ strings, and display coordinate operations available between two +CRSs. + +UPDATES +------- + +* Removed projects.h as a public interface (`#835 <https://github.com/OSGeo/proj.4/issues/835>`_) + +* Deprecated the proj_api.h interface. The header file is still available + but will be removed with the next major version release of PROJ. It is + now required to define :c:macro:`ACCEPT_USE_OF_DEPRECATED_PROJ_API_H` + before the interface can be used (`#836 <https://github.com/OSGeo/proj.4/issues/836>`_) + +* Removed support for the nmake build system (`#838 <https://github.com/OSGeo/proj.4/issues/838>`_) + +* Removed support for the ``proj_def.dat`` defaults file (`#201 <https://github.com/OSGeo/proj.4/issues/201>`_) + +* C++11 required for building PROJ (`#1203 <https://github.com/OSGeo/proj.4/issues/1203>`_) + +* Added build dependency on SQLite 3.7 (`#1175 <https://github.com/OSGeo/proj.4/issues/1175>`_) + +* Added :program:`projinfo` command line application (`#1189 <https://github.com/OSGeo/proj.4/issues/1189>`_) + +* Added many functions to ``proj.h`` for handling ISO19111 functionality (`#1175 <https://github.com/OSGeo/proj.4/issues/1175>`_) + +* Added C++ API exposing ISO19111 functionality (`#1175 <https://github.com/OSGeo/proj.4/issues/1175>`_) + +* Updated :program:`cs2cs` to use late-binding features (`#1182 <https://github.com/OSGeo/proj.4/issues/1182>`_) + +* Removed the ``nad2bin`` application.
