See NEWS for full changelog. Besides Bug fixes, notable changes are:
o Function proj_errno_string() added to proj.h API (#847)
o Validate units between pipeline steps and ensure transformation
sanity (#906)
o Print help when calling cct and gie without arguments (#907)
o CITATION file added to source distribution (#914)
o Webmercator operation added (#925)
o Enhanced numerical precision of forward spherical Mercator near
the Equator (#928)
o Added --skip-lines option to cct (#923)
o Consistently return NaN values on NaN input (#949)
o Removed unused src/org_proj4_Projections.h file (#956)
o Java Native Interface bindings updated (#957, #969)
o Horizontal and vertical gridshift operations extended to
the temporal domain (#1015)
There is an ABI break, and the API is changing enough that it's too
hard to figure out if not bumping API is safe. This is unfortunately
a big change and all of the geospatial world is going to have to cope.
5.0.0 Release Notes
-------------------
This version of PROJ introduces some significant extensions and
improvements to (primarily) the geodetic functionality of the system.
The main driver for introducing the new features is the emergence of
dynamic reference frames, the increasing use of high accuracy GNSS,
and the related growing demand for accurate coordinate
transformations. While older versions of PROJ included some geodetic
functionality, the new framework lays the foundation for turning PROJ
into a generic geospatial coordinate transformation engine.
[see upstream NEWS]
UPDATES
-------
o Introduced new API in proj.h.
- The new API is orthogonal to the existing proj_api.h API and the
internally used projects.h API.
- The new API adds the ability to transform spatiotemporal (4D)
coordinates.
- Functions in the new API use the "proj_" namespace.
- Data types in the new API use the "PJ_" namespace, with a few
historic exceptions such as XY, XYZ, LP and LPZ.
o Introduced the concept of "transformation pipelines" that makes it
possible to do complex geodetic transformations of spatiotemporal
coordinates by daisy chaining simple coordinate operations.
o Introduced cct, the Coordinate Conversion and Transformation
application.
o Introduced gie, the Geospatial Integrity Investigation Environment.
- Selftest invoked by -C flag in proj has been removed
- Ported approx. 1300 built-in selftests to gie format
- Ported approx. 1000 tests from the gigs test framework
- Added approx. 200 new tests
o Adopted terminology from the OGC/ISO-19100 geospatial standards
series. Key definitions are:
- At the most generic level, a *coordinate operation* is a change
of coordinates, based on a one-to-one relationship, from one
coordinate reference system to another.
- A *transformation* is a coordinate operation in which the two
coordinate reference systems are based on different datums, e.g.
a change from a global reference frame to a regional frame.
- A *conversion* is a coordinate operation in which both
coordinate reference systems are based on the same datum,
e.g. change of units of coordinates.
- A *projection* is a coordinate conversion from an ellipsoidal
coordinate system to a plane. Although projections are simply
conversions according to the standard, they are treated as
separate entities in PROJ as they make up the vast majority
of operations in the library.
o New operations:
- The pipeline operator (pipeline)
- Transformations:
+ Helmert transform (helmert)
+ Horner real and complex polynomial evaluation (horner)
+ Horizontal gridshift (hgridshift)
+ Vertical gridshift (vgridshift)
+ Molodensky transform (molodensky)
+ Kinematic gridshift with deformation model (deformation)
- Conversions:
+ Unit conversion (unitconvert)
+ Axis swap (axisswap)
- Projections:
+ Central Conic projection (ccon)
o Significant documentation updates, including
- Overhaul of the structure of the documentation
- A better introduction to the use of PROJ
- A complete reference to the new proj.h API
- a complete rewrite of the section on geodesic calculations
- Figures for all projections
o New "free format" option for operation definitions, which
permits separating tokens by whitespace when specifying key/value-
pairs, e.g. "proj = merc lat_0 = 45".
o Added metadata to init-files that can be read with the
proj_init_info() function in the new proj.h API.
o Added ITRF2000, ITRF2008 and ITRF2014 init-files with ITRF
transformation parameters, including plate motion model
parameters.
o Added ellipsoid parameters for GSK2011, PZ90 and "danish". The
latter is similar to the already supported andrae ellipsoid,
but has a slightly different semimajor axis.
o Added Copenhagen prime meridian.
o Updated EPSG database to version 9.2.0.
o Geodesic library updated to version 1.49.2-c.
o Support for analytical partial derivatives has been removed.
o Improved performance in Winkel Tripel and Aitoff.
o Introduced pj_has_inverse() function to proj_api.h. Checks if an
operation has an inverse. Use this instead of checking whether
P->inv exists, since that can no longer be relied on.
o ABI version number updated to 13:0:0.
o Removed support for Windows CE.
o Removed the VB6 COM interface.
BUG FIXES
------------
[various]
DEPRECATIONS
------------
[see upstream NEWS]
* proj_def.dat was missing from source distribution see
https://github.com/OSGeo/proj.4/issues/274 for more detail
* Update Geodesic library from GeographicLib
* Remove setlocale() use in pj_init_ctx()
* Renamed PVALUE in pj_param.c to prevent clash with Windows
One mismatched digest found in geography/libmemphis02:
# package libmemphis02
recorded SHA1 (memphis-0.2.3.tar.gz) = dbc2f61e49b996dc9ca91df0de9a08eb7adbfa9b
calculated SHA1 (memphis-0.2.3.tar.gz) = 85993bce12c3616fcf6e7682a70b9605883edec2
No changes were made to the libmemphis02 distinfo file
Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden). All existing
SHA1 digests retained for now as an audit trail.
Note that the PVALUE rename is not an ABI change and there is no revbump.
4.9.2 Release Notes
-------------------
o proj_def.dat was missing from source distribution
see https://github.com/OSGeo/proj.4/issues/274 for more detail
o Update Geodesic library from GeographicLib
o Remove setlocale() use in pj_init_ctx()
o Renamed PVALUE in pj_param.c to prevent clash with Windows
CVS: ----------------------------------------------------------------------
CVS: CVSROOT cvs.NetBSD.org:/cvsroot
CVS: please use "PR category/123" to have the commitmsg appended to PR 123
Note that this changes the shlib version from 0.8 to 9.0. While
that's bizarre, upstream does not view it as a bug.
(Note that 4.9.0 had an RC but not an actual release.)
Changes from 4.8.0:
4.9.1 Release Notes
-------------------
o 4.9.0RC2 release was abandoned because it was not promoted in a
timely fashion. Subsequent maintenance of tickets has continued,
and a new 4.9.1 release was issued in its place.
o Implement inverse solution for Winkel Tripel from Drazan Tutic #250
o More CMake configuration tweaks. The CMake configuration is probably
not at feature parity with the autotools builds at this point but it
is converging #256
o Tweak initialization ordering around setlocal which may have caused
issues #237
o Support out-of-tree autoconf builds more completely #247
o Fix NaN handling by geod_inverse and geod_polygon_addedge #251 & #253
o Update config.sub and config.guess #257
o Adapt Charles Karney's CMake patches for smoother build #258
o Define default PROJ_LIB location for CMake compilation #261
o Fix Windows compilation on PJ_aitoff.c
o Align CMake SOVERSION with autotools #263
o Regenerate nad/epsg with GDAL r28536 to avoid precision loss in TOWGS84
parameters, e.g. on Amersfoort / RD EPSG:4289 (#260)
o Add CMake project-config.cmake scripts (#264 from Charles Karney)
o Dial back test sensitivity #255
4.9.0 Release Notes
-------------------
o Implement CMake as an option for building PROJ.4
o Implement new virtual file api (projFileAPI) so that all access to grid
shift and init files can be hooked.
o Replace geodesic implementation with one from Charles Karney and add a
supported public interface (geodesic.h).
o Upgraded to EPSG 8.5.
o Removed old (deprecated) Java bindings in favor of the new api introduced
in 4.8.0.
o Implement the calcofi (Cal Coop Ocean Fish Invest Lines/Stations) projection
o Install projects.h again for applications that want access to internal
structures and functions despite the inherent fragility.
o Various bug fixes and cleanup.
o Added the CalCOFI pseudo-projection, #135
has an additional grid shift file. Add a test target; regression
tests now pass at least on NetBSD/i386 5.1_STABLE.
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.
