## 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.

 * 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)

to the 1.7.X maintenance releases are not mentioned hereafter.)

## In a nutshell...

* New GDAL drivers : GTX, HF2, JPEGLS, JP2OpenJPEG, JPIPKAK, KMLSUPEROVERLAY,
                     LOS/LAS, MG4Lidar, NTv2, OZI, PDF, RASDAMAN, XYZ

* RFC 33 changes the way PixelIsPoint is handled for GeoTIFF (#3838,#3837)

   robust to single quote characters in SRS strings
 * Fix to make CopyLayer() work when src layer is a SQL result layer (#3617)
 * Add OGR_SQLITE_SYNCHRONOUS configuration option that, when set to OFF,
   can speed up considerably write operations (e.g. on EXT4 filesystems),

 * avoid reducing array sizes if writing them in random order (#2427)

- Added PostGIS support.
- Pass attribute queries through to PostgreSQL.

o NTF Driver:
- Added support for GTYPE 5 geometries (a type of arc).
- Added support for GEOMETRY3D records in indexed (generic) datasets.

o TIGER/Line Driver:
- Added write support.
- Improved read support for TIGER 2000.

o OLE DB Provider:
- Added support for spatial queries via ICommand parameters.
- Added support for attribute queries by parsing out WHERE clause.
- In general substantial rework and extensions were made to make it
work with ESRI and AutoDesk clients.

o Added gdal/data/stateplane.txt - a test file with one line per state plane
zone for applications wanting to present options to users.

o Install ogrsf_frmts.a on install if building with OGR support enabled.

## OGR 1.1.5 Significant Bug Fixes

o OGRSpatialReference:
- Fix bug with extracting linear units from EPSG derived definitions.
- Fixed bug translating LCC from EPSG to WKT (importFromEPSG()).
- Improved IsSame() test for GEOGCS now.
- Fixed crash if PROJECTION missing from PROJCS definition.

o S-57:
- Improve recovery from corrupt line geometries.
- Read objects as generic if the object class is not recognised.
- Handle LIST attributes as a string, instead of as a single int.

o NTF:
- Fixed circle conversion to polylines to close the circle properly.
- Upped MAX_LINK to 5000 to handle much more complex geometries.

o DGN:
- Don't include elements with the complex bit set in extents
computations.

o OGRGeometry:
- Fixed WKT format (import and export) for various container types.
- WKT import fixed for coordinates, and Z coordinates.
