Updates

• Implement 'exact' authalic latitude->geographic latitude and use it in +proj=aea/cea/laea/eqearth/healpix/rhealpix (#4441)

• Implement uniform conversions between auxiliary latitudes (#4446)

• WKT2 parser: recognize DEFININGTRANSFORMATION (but ignore it) (#4484)

• Database: add values from alias_name table that were removed in older EPSG releases, to improve
  recognizing old WKT strings (#4490)

• proj_trans_bounds(): sample points within the source grid to avoid missing extent such as world-wide
  coverage from EPSG:4326 to ESRI:54099 (Spilhaus) (#4513)

• Enable -Wimplicit-fallthrough, -Wdeprecated-copy-dtor, -Wweak-vtables,
  -Wdocumentation-unknown-command when possible (#4516)

• Geostationary projection: speed up inverse spherical and ellipsoidal computation (#4523)

• WKT importer: better error message when BBOX is invalid (e.g south_lat > north_lat) (#4525)

• Added proj_geod_direct for PJ trasformation object (#4532)

• Support exporting Mercator (Spherical) on a sphere as Mercator_1SP in WKT1 (#4555)

• Database: update to EPSG v12.022 (#4562)

Bug Fixes

• proj_trans_bounds(): avoid erroring out, in some cases, when PJ* object is directly constructed
  from a PROJ pipeline (#4512)

• Fix issue related to D_Unknown_based_on_WGS_84_ellipsoid datum name (#4515)

• proj_trans_bounds(): fix 9.6.2 regression when going from long/lat crossing antimeridian to
  projected (#4526)

• opt_parse: avoid potential heap-buffer-overflow when parsing non-ASCII characters (affect
  cct and gie) (#4530)

• gie: fix memory leak on non existing input file (#4531)

• Database: referene nl_nsgi_nllat2018.tif and nl_nsgi_bongeo2004.tif grids (#4534)

• Fixes related to WKT import/export of DerivedGeodetic/GeographicCRS (#4536)

• Fix tolower()/toupper() implementation to not lead to undefined behavior (#4539)

• IAU2015 CRS: fix wrong code for coordinate system of North Polar and South Polar CRSs (#4545)

• createOperations(): fix a case involving 2 CompoundCRS, one with TOWGS84, and the 2
  verticalCRS differing by units (#4552)

• On SQLite query error, show first the error msg than the sql query (#4553)

• Allow geodesic inverse for meridional points on prolate ellipsoid (#4560)
