+ <title>Release 2.1.0</title>
+ <para>Release date: 2013/MM/DD</para>
+ <para>This is a minor release addressing both bug fixes and performance and functionality enhancements addressing issues since 2.0.3 release.
+ If you are upgrading from 2.0+, only a soft upgrade is required. If you are upgrading from 1.5 or earlier, a hard upgrade is required.</para>

+ <title>Enhancements</title>
+ <para>For detail of new functions and function improvements, please refer to <xref linkend="NewFunctions_2_1" />.</para>
+ <para>Much faster raster ST_Union, ST_Clip and many more function additions operations</para>
+ <para>For geometry/geography better planner selectivity and a lot more functions.</para>

+ <title>Important / Breaking Changes</title>
+ <para>For full detail of breaking function changes, please refer to <xref linkend="ChangedFunctions_2_1" /></para>
+ <para>#1962 ST_Segmentize - As a result of the introduction of geography support:
+ The construct SELECT ST_Segmentize('LINESTRING(1 2, 3 4)',0.5); will result in ambiguous function error.
+ You need to have properly typed object e.g. a geometry/geography column, use ST_GeomFromText
+ , ST_GeogFromText or SELECT ST_Segmentize('LINESTRING(1 2, 3 4)'::geometry,0.5);</para>
+ <para>#1653, Removed srid parameter from ST_Resample(raster) and variants
+ with reference raster no longer apply reference raster's SRID.</para>
+ <para>#2026, ST_Union(raster) now unions all bands of all rasters</para>
+ <para>#2089, liblwgeom: lwgeom_set_handlers replaces lwgeom_init_allocators.</para>
+ <para>#2150, regular_blocking is no longer a constraint. column of same name
+ in raster_columns now checks for existance of spatially_unique
+ and coverage_tile constraints</para>
+ <para>ST_Intersects(raster, geometry) behaves in the same manner as
+ ST_Intersects(geometry, raster) and is checked in geometry space.</para>
+ <para>point variant of ST_SetValue(raster) previously did not check SRID
+ of input geometry and raster.</para>
+ <para>ST_Hillshade parameters azimuth and altitude are now in degrees
+ instead of radians.</para>
+ <para>ST_Slope and ST_Aspect return pixel values in degrees instead of radians.</para>
+ </simplesect>

+ <title>Deprecated signatures</title>
+ <para>#2104, ST_World2RasterCoord, ST_World2RasterCoordX and
+ ST_World2RasterCoordY renamed to ST_WorldToRasterCoord,
+ ST_WorldToRasterCoordX and ST_WorldToRasterCoordY.
+ ST_Raster2WorldCoord, ST_Raster2WorldCoordX and
+ ST_Raster2WorldCoordY renamed to ST_RasterToWorldCoord,
+ ST_RasterToWorldCoordX and ST_RasterToWorldCoordY</para>
+ <para>ST_Estimated_Extent renamed to ST_EstimatedExtent</para>
+ <para>ST_Line_Interpolate_Point renamed to ST_LineInterpolatePoint</para>
+ <para>ST_Line_Substring renamed to ST_LineSubstring</para>
+ <para>ST_Line_Locate_Point renamed to ST_LineLocatePoint</para>
+ <para>ST_MapAlgebraFctNgb and 1 and 2 raster variants of ST_MapAlgebraFct.
+ Use ST_MapAlgebra instead</para>
+ <para>1 and 2 raster variants of ST_MapAlgebraExpr.
+ Use expression variants of ST_MapAlgebra instead</para>
