4.8.0 Release Notes ------------------- o Added the Natural Earth projection. o Added HEALPIX, rHEALPIX and Icosahedral Snyder Equal Area projections. o nad2bin now produces "CTable2" format grid shift files by default which are platform independent. o nad2nad removed, use cs2cs for datum shift operations. o projects.h no longer installed as a public include file. Please try to only use proj_api.h. o Add pj_get_spheroid_defn() accessor. o 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 logging. o Upgrade to EPSG 7.9. Some changes in ideal datum selection. o JNI bindings reworked, org.proj4.Projections deprecated in favor of org.proj4.PJ. o Added preliminary vertical datum support. o Fix various multithreading issues, particular in datum grid handling code. o Added support for the +axis= option for alternate axis orientations as part of a coordinate system (used for TM South Orientated support). o +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. 4.7.0 Release Notes ------------------- o Added in memory caching of init file search results for substantial acceleration in some application environments (like MapServer). o Regenerated nad/epsg init file with EPSG 7.1 database, including new support for Google Mercator (EPSG:3857). o Various thread safety improvements, including preliminary support for a mutex lock around some operations, like grid loading. 4.6.1 Release Notes ------------------- o Upgraded to EPSG 6.17 version for nad/epsg. Also corrected the precision problem introduced in the last version. o Added logic for tmerc projection to fail rather than return crazy results if more than 90 degrees away from the central meridian (#5). This change may only be temporary till a more comprehensive solution is found. o Fixed handling of extra text in cs2cs. o Renamed INSTALL to INSTALL.TXT. o The eqc projection has been generalized to include a latitude of origin. o Added the glabsgm (Gauss Laborde / Sphere Geometric Mean) projection, and gstmerc variation. o nad/IGNF init catalogue created. o added the ntf_r93.gsb datum shift file. o Add /Op in nmake.opt compile options to avoid VC7 optimization bug (#12) o Fix testvarious test script so it works properly when grid files available 4.6.0 Release Notes ------------------- o MAJOR: Rework pj_transform() to avoid applying ellipsoid to ellipsoid transformations as a datum shift when no datum info is available. o Avoid applying "change of ellipsoid" during datum shifting based on ellipsoids getting changed to spheres for spherical projections. o Upgrade to EPSG 6.13 o Added "900913" "Google Mercator" code in nad/esri.extra. o Avoid some static variable based multi-threading problems. o Improve error recovery if ctable style datum shift grid fails to load. o Support drive letters properly in PROJ_LIB paths for win32. o Fix occasional problem with DMS parsing. o Removed non-functional mpoly projection. o add lonlat, and latlon as aliases for longlat. 4.5.0 Release Notes ------------------- o Microsoft Visual Studio 8 compatibility changes. o Upgraded to EPSG 6.11.1 database. o Several bug fixes to pj_transform() to handle transient errors properly. o Fix Krovak projection (include +czech flag) o Added Roussilhe Stereographic projection from libproj4 (proj=rouss). o Added experimental +lon_wrap flag for alternate pj_transform() longitude wrapping behavior on output. 4.4.9 Release Notes ------------------- o Win32 build uses proj.dll by default now. o Added accessor functions for the datums, ellps, prime_meridians, units and main projection definition lists so they can be used on windows where data objects exported from the DLL don't work easily. o Added JNI (Java Native Interface) support within the jniwrap directory, and some supporting entry points directly in the proj dll/so. See --with-jni configure switch, and jniwrap/README. o Added the proj=stereoa and proj=geos projections, incorporated from Gerald's libproj4. o A few other bug fixes. 4.4.8 Release Notes ------------------- o Updated epsg file to EPSG 6.5, added other.extra pseudo-EPSG WMS definitions o Made significant fixes to prime meridian support. o Substantially change pj_datum_transform(), so it and pj_transform() will work between coordinate systems with different ellipsoids but no datum shift information (assume +towgs84=0,0,0). o Added pj_get_release() function. o Ensure pj_transform() will try to transform all points in provided list if even some might transform properly. o Improved the accuracy of Geocentric_To_Geodetic() via an iterative solution. o Various other bug fixes. 4.4.7 Release Notes ------------------- o Added NTv2 (.gsb) grid shift file support. o Modified datum shift support so that data file data is only loaded if needed. Also added 'null' grid as a fallback option, and support for making grids optional (prefix with '@' in +nadgrids). o Regenerated nad/epsg file with towgs84 parameters for non-greenwich prime meridians. o Updated nad/esri file with better generated form from Paul Ramsey. o Various bug fixes. 4.4.6 Release Notes ------------------- o Incorporated new lcca (Lambert Conformal Conic Alternate) projection from Gerald. o Updated 'espg' translation file for EPSG 6.2.2 with better support for prime meridians. o Added Prime Meridians via +pm command switch to cs2cs (and pj_transform). o Fixed bug with 7 parameter transforms. o Added 'esri' pseudo-epsg coordinate system file. o Cleanup so that PROJ.4 compiles clean as C++ code. o Added pj_get_def() to expand definitions of stuff like +init clauses. o Added a Krovak implementation (proj=krov). Note this may change again in the next release.
