== Backward compatibility issues ==

Due to the 2-digit number '10' in GDAL 1.10, the GDAL_VERSION_NUM macro has been changed.
The new advised way of testing the GDAL version number (for GDAL 1.10 or later) at compilation time is :

#ifdef GDAL_COMPUTE_VERSION /* only available in GDAL 1.10 or later */
#if GDAL_VERSION_NUM >= GDAL_COMPUTE_VERSION(1,10,0)
///
#endif
#endif

Testing of previous versions is of course unchanged.

== SWIG Language Bindings ==

General :
 * RFC 30: Correct the signature of Datasource.CreateDataSource() and DeleteDataSource(),  gdal.Unlink() to accept UTF-8 filenames (#3766)
 * Add Band.GetCategoryNames() and Band.SetCategoryNames()
 * Add Geometry.GetPoints() (only for Python and Java) (#4016)
 * Add Geometry.GetEnvelope3D()
 * Add Geometry.SimplifyPreserveTopology()
 * Extend SWIG Geometry.ExportToJson() to accept a list of options (#4108)
 * Add (OGR)DataSource.SyncToDisk()
 * Add SpatialReference.SetVertCS(), IsSameVertCS(), IsVertical(), SetCompound(), IsCompound()
 * Add SpatialReference.SetIGH() (#4060)
 * RFC 35: Add OGRLayer.DeleteField(), ReorderField(), ReorderFields(), AlterFieldDefn()
 * Add gdal.VSIFTruncateL()

CSharp bindings:
 * Implement the typemap for utf8_path in C# (#3766)
 * Correcting the signature of OGRDataSource.Open to make the utf8 typemap to work (#3766)

Java bindings:
 * Turn the gdalJNI, gdalconstJNI and osrJNI into package private classes
 * Make Layer.GetExtent() return null when OGR_L_GetExtent() fails.

Perl bindings:
 * The "Points" method of Geometry was not accepting its own output in the case of a single point. It accepted only a point as a list. Now it accepts a point both as a list containing one point (a ref to a point as a list) and a point as a list.
 * Fixed UTF-8 support in decoding names (datasource, layer, field etc.).
 * Assume all GDAL strings are UTF-8, handle all changes in typemaps.
 * Additions to Perl bindings due to new developments etc: Layer capabilities, GeometryType  method for Layer, improved create, new Export and Set methods for SpatialReference.
 * Detect context in a typemap which returns a array, this now returns a list in list context; the change affects at least GetExtent and GetEnvelope methods, which retain backward compatibility though new and/or changed methods: FeatureDefn::Name, FeatureDefn::GeometryIgnored, FeatureDefn::StyleIgnored, Feature::ReferenceGeometry, Feature::SetFrom, FieldDefn::Ignored, Geometry::AsJSON
 * Perl typemaps: more correct manipulation of the stack, more cases where a list is returned in a list context, better handling of callback_data @Band::COLORINTERPRETATIONS, Band methods Unit, ScaleAndOffset, GetBandNumber, RasterAttributeTable method LinearBinning
 * Typemaps for VSIF{Write|Read}L, tests and docs for some VSI* functions.
 * Perl bindings: better by name / by index logic, some checks for silent failures, return schema as a hash if wanted, support ->{field} syntax for features, return list attributes as lists or listrefs as wished so that ->{field} works for lists too (API change)

Python bindings:
 * Improvements for ogr.Feature field get/set
 * Add hack to bring Python 3.2 compatibility
 * First argument of VSIFWriteL() should accept buffers for Python3 compat
 * Fix reference leak in 'typemap(in) char **dict'
 * Add gdal.VSIStatL()
 * swig/python/setup.py : fix for virtualenv setups (#4285)
 * Layer.GetExtent() : add optional parameter can_return_null that can be set to allow returning None when OGR_L_GetExtent() fails
 * Make gdal.VSIFSeekL(), gdal.VSIFTellL() and gdal.VSIFTruncateL() use GIntBig instead of long for compat with 32bit platforms
 * Add script to build the python extensions with Python 2.7 and a mingw32 cross-compiler under Linux/Unix

Ruby bindings:
 * Build SWIG Ruby Bindings against modern Ruby versions (1.8.7 and 1.9.2) (#3999)

 * In GTiffDataset::Create(), set TIFFTAG_JPEGCOLORMODE=JPEGCOLORMODE_RGB when creating a TIFF with COMPRESS=JPEG and PHOTOMETRIC=YCBCR; In Crystalize(), backup the value of TIFFTAG_JPEGCOLORMODE and set it again after writing the directory (#2645)

 * Attempt to preserve PROJCS name in sMapInfo.proName, and to capture it as the PROJCS name when reading.  This will hopefully preserve symbolic names like NAD_1983_StatePlane_Ohio_South_FIPS_3402_Feet instead of replacing them with something generic like "Lambert_Conformal_Conic" (#2422).
 * avoid reducing array sizes if writing them in random order (#2427)
 * Prevent writing out cached information after the file has been closed.  Loosely related to (#2524).

 * Sample application for Band.GetHistogram.
 * Added the GDALAdjustContrast sample to demonstrate the image correction at the C# side.
 * Added Dataset.GetGCPs, Dataset.SetGCPs and GCPsToGeoTransform in the C# bindings (bugs #2426, #1986 and #1677
 * Added support for using OGR.Layer in Gdal.Polygonize
 * Changed the behaviour to use OSR.SpatialReference and OSR.CoordinateTransformation instead of defining the same classes in the OGR namespace
 * Changed the scope from internal to public of the required functions

SWIG Python related changes:
 * Fix layer __getitem__ bug (#2187)
 * add some sugar to ogr.DataSource.DeleteLayer to be able to take in either an index or a layer name.  If you give it a name, it *will* loop through all of the layers on the datasource.  This might be expensive depending on the driver.
 * add date/time fetching support to the generic GetField implementation... note this is not real 'datetime' support yet
 * a typemap for taking in lists of GDAL objects #2458
 * don't always return 0 for OGRErrs #2498
 * Added GetDefaultHistogram() with Python implementation
 * support for mingw Windows builds
 * Link with gdal_i.lib instead of gdal.lib when building with MSVC compiler. (#2578)

SWIG Perl
 * Added a more verbose description to the error message if projection method test fails. Skip testing parameters of International Map of the World projection since it fails (a bug?).
 * driver's create method's 2nd parameter, if given, is a listref
 * Support Cygwin by adding -lstdc++ to LIBS if OS is cygwin
 * Add GetDriver method as an alias to _GetDriver for DataSource. This fixes an unnoticed side-effect of rewrapping GetDriver for root class OGR.
 * force name to be a string for _GetLayerByName and make default for name 0
 * fix Layer::Schema
 * use perl hash also for fields in schema (the new API was not really implemented), add Schema method also for Feature
 * croak in Geometry::create unless type, wkt, wkb, or gml given
 * do not call UseExceptions when booting OGR wrappers since it is only done once when booting GDAL (of which OGR is a part), do not include inline functions from cpl_exceptions.i into OGR wrappers
 * add exception support as for OGR
 * use geometry factory methods in Geometry::create; accept also only coordinate parameters (i.e. auto-add 0 if needed) in Point method for Point type
 * Add wrappers for field types datetime and lists. Do not use the overloaded (field name) versions of the get/set functions.
 * GetField and SetField methods, which check for goodness of the field (name, index) and support dates, times, datetimes, and lists. In Row and Tuple the field value may be a listref.
 * Support HEXWKB in Geo::OGR::Geometry::create.
 * As* methods for Geometry as aliases for ExportTo; SpatialReference->create constructor
 * made needed links from parameters to typemaps to make Get- and SetDefaultHistogram methods work in Perl
 * support for mingw Windows builds

SWIG Java:
 * removed colortable from java bindings for now (#2231)

   precision.
 - geometries are now "coordinate dimension preserving" rather than dynamically
   figuring out dimension depending on whether Z is set.  So a geometry can
   now be 3D even if all z values are zero.
