= GDAL/OGR 3.0.1 Release Notes =

The 3.0.1 release is a bug fix release.

== Build ==

 * /vsis3/: for a long living file handle, refresh credentials coming from EC2/AIM (#1593)

== GDAL algorithms ==

 * GDALReprojectImage(): properly take into account source/target alpha bands
 * GDALCreateReprojectionTransformerEx(): do not emit error if reverse transformation fails, and fix crash when trying to use null reverse transformation
 * Warper: fix GDAL 2.3 regression in a situation with source nodata value, multiple bands and nearest resampling where the logic to detect which source pixels are nodata was inverted (#1656)
 * Contour generator: fix SegmentMerger list iterator skipping and out of bounds error. (#1670)

== GDAL core ==

 * GDALInvGeoTransform(): make it work with scale and rotation/skew coefficients of small absolute value (#1615)
 * GDALCopyWholeRasterGetSwathSize(): fix potential int overflows for big values of GDAL_SWATH_SIZE or GDAL_CACHEMAX

== GDAL utliities ==

 * gdal_translate: Make 'gdal_translate foo.tif foo.tif.ovr -outsize 50% 50% -of GTiff' work
 * gdalwarp: fix wrong axis order when using source/target CRS being a geographic3D CRS such as EPSG:4979, and with vertical shift grid application (#1561, 3.0 regression)
 * gdal_calc.py: Fixed NaN-streaking in output images when the --allBands option is given to tiled images, and removed redundant calculation of nXValid.
 * gdal_polygonize.py: fix outputing to geojson without explicit -f switch (#1533)
 * gdallocationinfo: emit verbose error when dataset canot be opened (#1684)

== GDAL drivers ==

ENVI driver:
 * fix potential use of invalid pointer on some unusual std::string implementations (#1527)
 * add read support for reading GCPs (#1528), and fix off-by-one offset on line,pixel on reading GCP

GTiff driver:
 * make WEBP_LEVEL to be honored in Create() mode (#1594)
 * reset m_bGeoTIFFInfoChanged flag in FlushDirectory()
 * PushMetadataToPam(): early exit when PAM is disabled, to avoid error messages

GXF driver:
 * avoid closing the file pointer before being sure this is a GXF driver, otherwise this can prevent the opening of some raw format files (#1521)

HDF5 driver:
 * Make GH5_FetchAttribute(CPLString) more robust and able to cope with variable-length string

ISIS3 driver:
 * fix parsing of lists in JSon metadata, and quote string items when writing lists when needed (#1510)

KEA driver:
 * return error when deleting metadata item rather than crashing (#1681)

NITF driver:
 * fix parsing of SENSRB TRE (#1520)

RS2 driver:
 * add half-pixel shift to reported GCP line and column numbers (#1666)

TileDB driver:
 * removed ambiguous use of size_t
 * TILEDB_LIBS added for windows build

VRT driver:
 * Python pixel functions: also probe libpython3.Xm.so.1.0 (#1660)

== OGRSpatialReference ==

 * EPSG:4326 to EPSG:3857: fix invalid output with some input coordinates (3.0 regression)
 * GetAxis(): make it work with a compound CRS (#1604)
 * importFromWkt(): emit a CPLError() in case of import failure (refs #1623)

== OGR drivers ==

EEDA driver:
 * fix startTime / endTime comparisons that were incomplete in #1506

GeoJSON driver:
 * fix recognizing some documents with members sorted alphabetically (#1537)
 * avoid SetFeature() to repeat first feature when looping over features (#1687)

ElasticSearch driver:
 * set 'application/json' in RunRequest() with POST (#1628)
 * GeoJSON type field should be mapped as text in ES>=5

GPKG driver:
 * change default value of OGR_GPKG_FOREIGN_KEY_CHECK to NO, so as to avoid issues in downstream software
 * insert more accurate spatial extent in gpkg_contents
 * fix memory leak in case of corrupted database. Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=14683.

KML driver:
 * set OAMS_TRADITIONAL_GIS_ORDER for SRS returned on returned layers

MapInfo driver:
 * TAB: don't left truncate numeric values in the .dat when the field formatting is incompatible, but error out (#1636)

MSSQLSpatial driver:
 * Fix handling empty geometries (#1674)
 * Fix handling mixed geometries (#1678)

MVT driver:
 * make CONF option accept a filename as well

PostgreSQL driver:
 * do not attempt to create VARCHAR(n) columns with n >= 10485760 (#1508)

Shapefile driver:
 * better deal with empty .shp+.shx and SHAPE_RESTORE_SHX (#1525)
 * fix crash when creating a layer with a wkbNone geometry type but a SRS (3.0 regression)
 * launder layer name to get Windows compatible filename

WaSP driver:
 * on creation, make sure the layer geometry type set on the feature definition is wkbLineString25D

== SWIG bindings ==

 * add osr.SetPROJSearchPath(path) that can be used since setting PROJ_LIB from C# does no work (#1647)

== Python bindings ==

 * honour gdal.UseExceptions() in numpy related methods (gdalnumeric module) (#1515)
