    5 '''Note for users:''' The last bug fixes and improvements have been finally included in GDAL 1.10, [http://trac.osgeo.org/gdal/wiki/Release/1.10.0-News released on April 2013]. So, it's stable now. Henceforth, the bug fixes and small improvements will be added to 1.10 branch. Bigger improvements will be added to trunk.
     5""Note for users""": Thanks to the last improvements made by Jorge Arévalo and Even Rouault, the driver is now much faster and stable. But it's not in the stable branch yet. If you want to use this improved version, should download the [http://www.gisinternals.com/sdk/ nightly builds for Windows], or donwload and compile [http://trac.osgeo.org/gdal/wiki/DownloadSource#NightlySnapshots the last snapshots from trunk]

    7 '''Note for developers:''' There is an open discussion on GDAL driver design at [http://trac.osgeo.org/postgis/wiki/WKTRaster/GDALDriverSpecificationWorking PostGIS Raster wiki]
     7With this version, you will enjoy those new and exciting features:
     8
     9 * Implemented multi-tile caching if cache size is big enough
     10 * Implemented multi-tile multi-band caching if cache size is big enough
     11 * Avoided initial full scan table in some situations (no where, PKID index, GIST index)
     12 * Added a AVERAGE_APPROX_RESOLUTION strategy that is now the default, and
     13  is used to compute quickly the dataset resolution on a small sample of rows,
     14  when resolution isn't advertized in raster_columns
     15 * Fixed caching of connexions in PostGISRasterDriver::GetConnection() to take
     16  into account database name (and thread)
     17 * Revised how overviews are handled.
     18 * Fixed quadtree insertion.
     19 * Fixed handling of positive y resolution (ungeoreferenced rasters)
     20 * Optimized retrieval of tiles per PKID (with a map)
     21 * Made driver work when called from non C locale (e.g. QGIS)
     22 * Accepted connection strings that have no host=, port= or user= (like OGR PG driver)
     23 * Added tolerance when fetching tiles per coordinates.
     24
     25If you prefer a stable version, without those new features, '''choose the 1.10.1 branch'''. Previous versions were buggy and unstable.

    928[[BR]]
    … …  
    1736  * Create and modify raster on PostGIS database.
    1837
    19 '''Please, use GDAL 1.10. The driver packed with previous GDAL versions was buggy and unstable, and it won't work with the last versions of PostGIS Raster (since it was included in PostGIS trunk).'''

    2138Take into account that:
    2239  * GDAL doesn't require PostgreSQL/PostGIS installed in your machine to work. But...

    2542So, if you want to use GDAL PostGIS Raster driver:
    26  * ALWAYS use GDAL version 1.10 from trunk or higher.
     43 * ALWAYS use GDAL version 1.10.1 or trunk version.
    2744 * Apart from this, if you want to use the driver against your own PostGIS version, use PostGIS 2.0
