# PROJ Release Notes

## 9.7.0

### 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)
