== 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.

 * 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

 * Typemaps for VSIF{Write|Read}L, tests and docs for some VSI* functions.
 * Perl bindings: better by name / by index logics, 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()

 * 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)

 * 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)
