9.2.0 Release Notes
-------------------
Updates
--------
+ Database
o EPSG updated to EPSG 10.082 (#3609)
o ESRI objects updated to v3.1.0 (#3575)
o Added Slovenian geoid model SLO-VRP2016/Koper (#3610)
+ Projections
o Added generic Space Oblique Mercator (#3338)
o Inverse eck4: Add checks for projection domain (#3625)
+ Transformations
o Added support for NADCON5 grids and transformation method (#3510)
o Added option ONLY_BEST=YES (#3535)
When enabled only use the best possible transformation between two CRS's can be
instantiated. If the best possible transfomations can't be instantiated it will
fail instead of opting for the next best transformation.
With ONLY_BEST=YES a transformation will fail if a needed grid is unavailable.
The option can be toggled in proj.ini and with --only-best in cs2cs.
o Implement 'Similarity transformation' (EPSG:9621) and import related
tranformations from EPSG (#3578)
o Optimise transformations between GDA94, GDA2020 and WGS84 (#3621)
+ Performance improvements
o Pass PJ_COORD by reference for fwd4d and inv4d callbacks (#3503)
o Improved of inverse meridian length calculations (#3516)
o Avoid very poor performance on a geographic CRS whose datum name is the alias
of an official one (#3624)
+ Well-Known Text improvements
o Support WKT:2019 COORDINATEMETADATA[] construct (#2711)
o implement alterCSLinearUnit for CompoundCRS (#3325)
o Implement alterCSLinearUnit for BoundCRS (#3327)
o Added PJ_TYPE_DERIVED_PROJECTED_CRS (#3488)
o Added support for ISO19111 CoordinateMetadata class (#3562)
o Update WKT import to support WKT2 corrigendum (#3573)
o WKT import: Make axis direction and range meaning enumeration case
insensitive as mandated by spec (#3577)
o Implement AffineCS and handle it in WKT (#3579)
o WKT1 parser: Support inf as inverse flattening value (#3626)
+ PROJJSON
o Version number changed to 0.6

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.

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

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
