This page lists rasdaman versions, together with the change history.
Starting with version 8.2 we provide summaries of the main changes done with each roll-out.

Alternative ways of obtaining rasdaman are listed in the [wiki:Download] area.

== Version 9.0.0 ==
 * For download and installation check the ([wiki:RasdamanQuickInstall debian]) [wiki:Install installation] and [wiki:RasdamanReleaseProcess release process] guides.

=== Changes and new features ===
 * tile ids are now stored as long ints in the database rather than double.
   * '''note:''' this is a backwards incompatible change over rasdaman 8.x, i.e. once `update_db.sh` is run, the database (RASBASE) will be converted to the new format and will be only readable by rasdaman 9+
 * the petascopedb schema (tables with prefix `'PS9_'`) has been completely redesigned to work in cooperation with [wiki:SecoreUserGuide SECORE]
  * '''note:''' petascope 9.0 is incompatible with the old petascope schema, and requires running `update_petascopedb.sh --migrate` to make the old petascopedb compatible
  * before running `update_petascopedb.sh --migrate`, it is necessary to remove the `$RMANHOME/share/rasdaman/petascope/update*.sql` files, which may have been left from an earlier installation.
  * similarly it is necessary to remove `$RMANHOME/etc/petascope.properties`, as more parameters have been added and `make install` will not overwrite and outdated configuration file.
 * support for CRS-aligned irregularly gridded coverages (''referenceable'' grids as by GML nomenclature, with axis parallel to the axes of the CRS).
 * support for compound CRS, either spatial, temporal, or spatio-temporal.
 * support for Index CRSs for unreferenced images.
 * support for CRS slicing (interim `@<axis1>,__,<axisN>` notation).
 * support for ISO8601 timestamps in WC*S subsettings (use double-quotes delimiters to switch from numeric coordinate to date).
 * WCS service and service provider metadata is moved from Java templates to the database.
 * GMLCOV coverage metadata is richer and more flexible: all GML fields are configurable in the database.
 * rasdaman collections and WC*S coverage names can be different: a coverage corresponds to an MDD, while a collection can contain multiple MDDs.
 * more powerful systemtests, with oracles support and scripting.
 * initial support for multi-coverages is available in petascope (specifically multipoint coverages). To enable this feature PostGIS 2.0+ is required, otherwise it will be disabled.
 * the WCS CRS extension, partially implemented in the previous version (subsettings but no output reprojection) has been removed.
 * OGC WCS compliance is ensured (KVP protocol extension).
 * SECORE only supports URLs now, URN support is removed as OGC URNs have been deprecated for a long time already.
  * '''note:''' this is an incompatible change, so an existing SECORE database must be removed (rm -rf $CATALINA_HOME/webapps/secoredb/*), so that a new database containing only URL identifiers can be initialized.

''Quick upgrade guide''
1. `$ rm $RMANHOME/share/rasdaman/petascope/update*.sql`
1. `$ rm -rf $CATALINA_HOME/webapps/secoredb/*`
1. `$ find / -name .basex`
 * edit it and set ''DBPATH = /var/lib/tomcat6/webapps/secoredb/'', or any other directory writeable by the tomcat user
1. `$ mv $RMANHOME/etc/petascope.properties $RMANHOME/etc/petascope.properties.bak`
1. `$ make && make install`
1. edit and update `$RMANHOME/etc/petascope.properties`
1. `$ update_db.sh`
1. `$ update_petascopedb.sh --migrate`

== Version 8.3.0 ==

Download link: [http://www.rasdaman.com/Download/rasdaman-8.3.0.tar.gz rasdaman 8.3.0]

=== Known Issues ===

 * the ''make'' process breaks if no ''--war-dir'' option is specified in the ''./configure'' step.


=== Server ===
 * compilation on OS X
 * rasgeo tool for GDAL-based image file import added to applications
 * rasdaman web client toolkit (raswct) has been added to applications
  * accompanying developer's manual can be found in manuals_and_examples/manuals
 * fixed returning wrong error code on exception in rasgeo
 * CSV formatter properly prints point queries
 * fix exporting data of base type uint8, int8, uint32, float, etc. to TIFF
 * added support for multiband TIFF images

 * specific netcdf variable can be imported/exported, e.g. netcdf($1, "var=Base_reflectivity")
 * fix the default definition of the RPC server in rasmgr.conf
 * added --with-docs option to the configure script, to control whether doxygen documentation should be generated during installation.
 * added option for generating position independent code (PIC), usually necessary on 64bit systems for generating proper shared objects.
 * fix rasdl segfaulting when executed with invalid parametars
 * fix rasdl segfaulting when types with a specified extent are present in the database
 * fix type checking when updating with a file in some specific format. At the type-checking stage the actual type is not yet known as the conversion hasn't been evaluated.
 * fix rasmgr segfaulting on Debian Wheezy 64bit, gcc 4.6
 * fix make clean for java
 * add rview binary and modify Makefiles so that it's properly installed on make install
 * add includes for mkdir in rasmgr_config.cc

 * the server should not fail if it fails reading some of the coverages
 * fix parsing of CRS in WCS 2.0
 * fix failed post req2 by including an ows:Constraint under OperationsMetadata in the Capabilities response
 * fix failed core req8 (URLs in OperationMetadata were same for different servlet locations), and failed core req12 (invalid KVP request didn't result with exception).
 * fix req17 by adding XML schema validation of XML requests.
 * perform initialization at servlet startup instead of at the first request.
 * fix installation of petascope settings
 * remove the version attribute of the ServiceMetadata element
