8.2.0 Release Notes
-------------------
Announcements
-------------
From PROJ 9.0.0 and onwards CMake will be the only build system bundled
with the PROJ package. As a consequence support for Autotools builds will
stop when the 8.2 branch of PROJ reaches end of life. We encourage
everyone to adjust their build workflows as soon as possible and report
any discrepancies discovered between Autotools and CMake builds.
Details about the build system unification can be found in PROJ RFC 7.
Updates
-------
o Added the S2 projection (#2749)
o Added support for Degree Sign on input (#2791)
o ESRI WKT: add support for import/export of (non interrupted)
Goode Homolosine (#2827)

o Add proj_create_conversion_pole_rotation_netcdf_cf_convention() to
address netCDF datasets using a pole rotation method (#2835)

o Add support for GeodeticCRS using a Spherical planetocentric
coordinate system (#2847)
o PROJJSON: support additional properties allowed in id object (version,
authority_citation, uri) for parity with WKT2:2019 (#2850)
o Database layout modified to include "anchor" field to geodetic_datum and
vertical_datum tables, consequently database layout version is increased
to 1.2 (#2859)
o proj_factors(): accept P to be a projected CRS (#2868)
o Add IAU_2015 CRS definitions (#2876)
o CRS::extractGeodeticCRS(): implement for DerivedProjectedCRS (#2877)
o Added proj_trans_bounds() (#2882)
o CMake: add a BUILD_APPS to be able to disable build of all applications (#2895)
o CMake: generate invproj/invgeod binaries (symlinks on Unix, copy otherwise)
(#2897)
o CMake build: add generate_wkt1_parser and generate_wkt2_parser manual
target, and logic to detect when they must be run (#2900)
o Add fallback strategy for tinshift transform to use closest triangle for
points not in any (#2907)
o Database: update to EPSG v10.038 (#2910)
o CMake: revise handling of symbol export and static builds (#2912)
Bug fixes
---------
o Fix O(n^2) performance patterns where n is the number of steps of
a pipeline (#2820)
o Detect ESRI WKT better in certain circumstances (#2823)
o Fix performance issue on pipeline instanciation of huge (broken)
pipelines (#2824)
o Make sure to re-order projection parameters according to their canonical
order if needed (#2842)
o Fix database access across fork() when SQLite3 doesn't use pread[64]() (#2845)
o Fix error in implementation of Inverse ellipsoidal orthographic projection
that cause convergence to sometimes fail (#2853)
o Fix handling of edge-case coordinates in invers ortho ellipsoidal
oblique (#2855)
o proj_normalize_for_visualization(): set input and output units when there
are several alternative transformations (#2867)
o CRS::identify(): fix ignoring CS order when identifying a geodetic CRS
by a PROJ string with just the ellipsoid (#2881)
o Fix CRS Equality with PROJ parameter order (#2887)
o WKT concatenated operation parsing: fix when a axis order reversal conversion
is the first or last operation (#2891)
o WKT1 parser: recognize Lambert_Conformal_Conic as projection name for
LCC 1SP or 2SP (#2893)
o CMake: Always build gie if testing is requested (#2899)
o Geographic 3D CRS: allow to export to WKT1:ESRI if only the GEOGCS is known
(and thus extrapolating a VERTCS) (#2902)
o lib_proj.cmake: add a PROJ::proj alias and add BUILD_INTERFACE include
directories, so that proj can be used as a subdirectory of a larger
project (#2913)

CRS that has a fallback-to-PROJ4-string behaviour and is a BoundCRS of a
GeographicCRS (#2808)
o WKT2 import/export: preserve PROJ.4 CRS extension string in REMARKS[] (#2812)
o BoundCRS: accept importing/exporting in WKT2 and PROJJSON the
scope/area/extent/id attributes (#2815)

8.0.0 Release Notes
-------------------
With the release of PROJ 8 the proj_api.h API is finally removed. See
https://proj.org/development/migration.html for more info on how to migrate
from the old to the proj.h API.
With the removal of proj_api.h it has been possible to simplify error codes
and messages given by the software. The error codes are exposed in the API.
Several improvements has been made to the command line utilities as well as
tweaks in the underlying API.

7.0.0 Release Notes
-------------------
The major feature in PROJ 7 is significantly improved handling of gridded
models. This was implemented in RFC4 (https://proj.org/community/rfc/rfc-4.html).
The main features of the RFC4 work is that PROJ now implements a new grid format,
Geodetic TIFF grids, for exchaning gridded transformation models. In addition
to the new grid format, PROJ can now also access grids online using a data
store in the cloud.
The grids that was previously available via the proj-datumgrid packages are now
available in two places:
1. As a single combined data archive including all available resource files
2. From the cloud via https://cdn.proj.org
In Addition, provided with PROJ is a utility called projsync that can be used
download grids from the data store in the cloud.
The use of the new grid format and the data from the cloud requires that
PROJ is build against libtiff and libcurl. Both are optional dependencies
to PROJ but it is highly encouraged that the software is build against both.
ATTENTION: PROJ 7 will be last major release version that includes the proj_api.h
header. The functionality in proj_api.h is deprecated and only supported in
maintenance mode. It is inferior to the functionality provided by functions
in the proj.h header and all projects still relying on proj_api.h are encouraged
to migrate to the new API in proj.h. See https://proj.org/development/migration.html
for more info on how to migrate from the old to the new API.
