default when converting to GML. Add gml:boundedBy in \ 
gmljp2:GMLJP2RectifiedGridCoverage
 * GMLJP2 v2: ensure KML root node id unicity when converting annotations on the \ 
fly. When generating GML features, make sure that PREFIX and TARGET_NAMESPACE \ 
are unique when specifying several documents.

Algorithms:
 * RPC transformer: speed-up DEM extraction by requesting and caching a larger \ 
buffer, instead of doing many queries of just a few pixels that can be costly \ 
with VRT for example

as in GDALCreateRPCTransformer() if <PixErrThreshold> is missing (so use \ 
0.1 instead of 0.25 as before)

SRC_APPROX_ERROR_IN_PIXEL, DST_APPROX_ERROR_IN_SRS_UNIT, \ 
DST_APPROX_ERROR_IN_PIXEL, REPROJECTION_APPROX_ERROR_IN_SRC_SRS_UNIT and \

GDALDummyProgress (#6552)
 * GDAL contour: fix incorrect oriented contour lines in some rare cases (#6563)
 * Warper: multiple performance improvements for cubic interpolation and uint16 \ 
data type
 * Warper: add SRC_ALPHA_MAX and DST_ALPHA_MAX warp options to control the \ 
maximum value of the alpha channel. Set now to 65535 for UInt16 (and 32767 for \ 
Int16), or to 2^NBITS-1. 255 used for other cases as before
 * Warper: avoid undefined behaviour when doing floating point to int \ 
conversion, that may trigger exception with some compilers (LLVM 8) (#6753)
 * OpenCL warper: update cubicConvolution to use same formula as CPU case (#6664)
 * OpenCL warper: fix compliance to the spec. Fix issues with NVidia opencl \ 
(#6624, #6669)

 * avoid resetting error potentially emitted by ExecuteSQL() (#6194)
 * sanitize management of quoting for FID column at layer creation
 * fix to get SRID on result layer with PostGIS 2.2
 * in copy mode (the default on layer creation), do not truncate the \ 
concatenated string list to the field width (#6356)
 * make such that GEOMETRY_NAME layer creation option is honoured in ogr2ogr \ 
when the source geometry field has a not-null constraint (#6366)
 * read and set DESCRIPTION metadata item from/into pg_description system table; \ 
add DESCRIPTION layer creation option
 * support int2[] and numeric[] types, better map float4[] type
 * remove code that was intended to handled binary cursors as it cannot be triggered
 * fix append of several layers in PG_USE_COPY mode and within transaction \ 
(ogr2ogr -append use case) (#6411)

PGDump driver:
 * fix issue with case of ogc_fid field in case the FID  layer creation option \ 
is not set by user or by ogr2ogr (related to #6232)
 * in copy mode (the default on layer creation), do not truncate the \ 
concatenated string list to the field width (#6356)
 * make such that GEOMETRY_NAME layer creation option is honoured in ogr2ogr \ 
when the source geometry field has a not-null constraint (#6366)
 * set DESCRIPTION metadata item from/into pg_description system table; add \ 
DESCRIPTION layer creation option

Shapefile driver:
 * accept opening standalone .dbf files whose header length is not a multiple of \ 
32 bytes (#6035)
 * fix REPACK crash on shapefile without .dbf (#6274)
 * add capability to restore/build a missing .shx file when defining \ 
SHAPE_RESTORE_SHX to TRUE (#5035)
 * avoid CreateLayer() to error out when passed wkbUnknown | wkb25D (#6473)

SQLite/Spatialite driver:
 * support file:xxx URI syntax (derived from patch by joker99, #6150)
 * fix heuristics in OGRSQLiteSelectLayer::GetExtent() to not be used when \ 
there's a sub SELECT (#6062)
 * fix crash on GetLayerByName('non_existing_table(geom_column)') (#6103)
 * fix OGRSQLiteSelectLayerCommonBehaviour::GetBaseLayer() to no longer 'eat' \ 
consecutive characters in layer name (#6107)
 * Spatialite: turn debug messages warning about update not being supported \ 
because of missing or too old spatialite version as errors, and return NULL to \ 
the caller (#6199)
 * fix memleak in OGRSQLiteTableLayer destructor when updating geometry_columns_time
 * VFS: increase mxPathname to 2048 by default, and provide \ 
OGR_SQLITE_VFS_MAXPATHNAME config option to be able to configure that higher if \ 
that would be needed. Useful when dealing with very long names like \ 
/vsicurl/.... with AWS S3 security tokens
 * VFS: do not probe -wal files on /vsicurl/

SXF driver:
 * fix wrong use of endianness macros to fix behaviour on big-endian hots
 * add recoding from CP1251 for TEXT attribute that is now decoded
 * fix various issues (#6357)

VRT driver:
 * implement CloseDependentDatasets()
 * fix editing with 'direct' geometry mode which could cause attribute column to \ 
be empty (#6289)
 * fix crash with a OGRVRTWarpedLayer using a source layer that would have non \ 
geometry column (unlikely to happen currently as this would require explicit \ 
disabling it, but more likey with following commit that createe VRT non-spatial \ 
layer implictly when the source is non-spatial, linked to #6336)
 * avoid creating an implicit wkbUnknown geometry field when the source has no \ 
geometry column and there's no XML elements related to geometry fields (#6336)

XLSX driver:
 * fix reading sheets with more than > 26 columns and 'holes' (#6363)

XPlane driver:
 * extend ICAO identifiers to 5 digits (#6003)

== SWIG Language Bindings ==

All bindings:
 * add a options parameter to gdal.ReprojectImage() to pass warp options
 * Change ReadRaster and WriteRaster to use GIntBig and the *IOEx-methods
 * prevent NULL file pointer from being passed to VSIF*L functions
 * make gdal.Rename() accept Unicode strings
 * add SpatialReference.GetAxisName() and SpatialReference.GetAxisOrientation() \ 
(#6441)
 * add SpatialReference.GetAngularUnitsName() (#6445)

Java bindings:
 * Fix typemap for input parameter of type GIntBig (fixes GetFeature(long), \ 
DeleteFeature(long), etc...) (#6464)
 * Bump minimal java version to 1.5 in case SWIG generates anotations (#6433, \ 
patch by Bas Couwenberg)
 * GNUmakefile: add -f in rm commands
 * GNUmakefile: add support for all hardening buildflags

Perl bindings:
 * Fix #6050: string formatting in croak.
 * Perl Makefile.PL: add support for all hardening buildflags (#5998)
 * use strict and warnings in overridden constructors.
 * add $VERSION to ogr_perl.i (OGR.pm), which is required by pause.perl.org.
 * Add some basic module info for CPAN.
 * Bugfix for Geo::OGR::Feature->new().
 * Add many utility level algorithms as methods to various classes.
 * New class for XML stuff
 * New Makefile.PL, which can download and build GDAL. This allows automatic \ 
testing of the CPAN module.
 * Wrap VSIStdoutSetRedirection and allow creating datasets via an object, which \ 
can write and close.
 * Geo::OGR::Driver and Geo::OGR::DataSource are now Perl wrappers for \ 
respective GDAL classes.
 * Add to the error stack also errors from the bindings
 * Fix sending utf8 from Perl to GDAL. Should also remove some \ 
"uninitialized value" warnings.
 * ReadTile and WriteTile methods for Dataset, ReadTile accepts now tile size \ 
and scaling algorithm.
 * Improved Parent - Child management.
 * Improved support for 64bit ints.
 * Measures support in Geometry class.
 * Many new tests

Python bindings:
 * make Feature.ExportToJson() output boolean value for a boolean field
 * support floating point coordinates for the source windows of \ 
Band.ReadRaster() and Band.ReadAsArray()
 * fix build with SWIG 3.0.6 (#6045)
 * make gdal.OpenEx() throw a Python exception in case of failed open when \ 
exceptions are enables with gdal.UseExceptions() (#6075)
 * Disable opening a NumPy dataset with a filename returned by \ 
gdal_array.GetArrayFilename(() unless GDAL_ARRAY_OPEN_BY_FILENAME is set to TRUE
 * disable the warning about using deprecated wkb25DBit constant as it uses a \ 
trick that prevents the bindings from being used by py2exe / pyinstaller (#6364)
