= GDAL/OGR 2.1.3 Release Notes = 

The 2.1.3 release is a bug fix release.

== Build ==

* Windows: include plugins in clean, oci: also clean dll
* windows: makegdal_gen.bat: update script to generate most recent Visual C++ project files (#6635)

== Port ==

* CPLHTTPFetch(): add a CAINFO option to set the path to the CA bundle file. As a fallback also honour the CURL_CA_BUNDLE and SSL_CERT_FILE environment variables used by the curl binary, which makes this setting also available for /vsicurl/, /vsicurl_streaming/, /vsis3/ and /vsis3_streaming/ file systems (#6732)
* Fix GetDiskFreeSpace() on 32bit Linux to avoid 32bit overflow when free disk space is above 4 GB (#6750)

== GDAL algorithms ==

* Warper: avoid undefined behaviour when doing floating point to int conversion, that may trigger exception with some compilers (LLVM 8) (#6753)
* OpenCL wrapper: do not use CL_MEM_COPY_HOST_PTR flag as it is forbidden by the opencl spec for clGetSupportedImageFormats() use case. Fix for NVidia use case (#6624)
* OpenCL wrapper: fix wrapping of Float32 data type with NVIDIA OpenCL (#6669)

== Utilities ==

* gdalinfo -json: fix order of points in wgs84Extent.coordinates (github #166)
* gdal_rasterize: fix segfaults when rasterizing into an ungeoreferenced raster, or when doing 'gdal_rasterize my.shp my.tif' with a non existing my.tif (#6738)
* gdal_calc.py: fix usage message

netCDF driver:
* fix erroneous detection of a non-longitude X axis as a longitude axis that caused a shift of 360m on the georeferencing (#6759)

OpenJPEG driver:
* for single-line organized images, such as found in some GRIB2 JPEG2000 images, use a Wx1 block size to avoid huge performance issues (#6719)

AmigoCloud driver:
* add option to receive an AmigoCloud API key in the connection string, fix page size (github #137)

GeoJSON driver:
* fix segfaults on writing on NULL geometry with -lco WRITE_BBOX=YES (#6698)
* support multilinestring from esriGeometryPolyline (#6773)

GPKG driver:
* don't show Spatialite vgpkg_ virtual tables (#6707)

Shape driver:
* when rewriting the geometry of the last record in the .shp, do it at the file offset it previously used (#6787)

SQLite driver:
* Spatialite: do not report some BLOB columns as geometry columns of tables/views (when found before the geometry column(s)) (#6695, #6659)
* fix update of features with multiple geometry columns (#6696)
* Spatialite: avoid spatial views to cause layers 'layer_name(geometry_name)' to be publicly listed (#6740)
* SQLite/GPKG: add explicit error message when trying to open a read-only WAL-enabled database, and make sure when closing a WAL-enabled database opened in read-only mode to reopen it in read-write mode so that the -wal and -shm files are removed (#6776)

* swig/python/setup.py: fix build issues when CXX is defined in the environment (#6765)
