Version 0.8 (2012-XX-XX)

	* The schema for the DaCHS-internal metadata tables changed.  To adapt
		your database, run

			gavo imp --system //dc_tables

		(to fill the tables again, say gavo pub -ma, but you'll do so in the
		next step anyway)

  * There's now a table tap_schema.groups.  To create it, say:

      gavo imp //tap createSchema 

    Do not give --system here unless you already have the tap_schema.groups
    table; if you do give --system, the existing tables will be re-created and
    you will have to say gavo pub -ma to re-fill them.

  * The schema of the service list has changed again, and the changes
    require a republication of all services.  After the update, run

      gavo imp --system //services
      gavo pub -ma

 	* Some ADQL user-defined functions are now implemented as Postgres
	  stored procedures.  Say::

			gavo imp //adql

		define those.

	* The UWS code now writes to the UWS tables with less privileges.
	  To let it do that, you must update the privileges on all queue tables;
	  in standard DaCHS, that's only the TAP table, so simply say:
	  
	  	gavo imp -m //tap createJobTable

  * The organization running the dc is now configurable.  If you are
    running the registry interface, you must now give authority.managingOrg,
    organization.title, organization.description, and 
    organization.referenceURL in defaultmeta.txt.
    authority.managingOrg usually is ivo://<your authority>/org.

  * The former readRoles and allRoles attribute of table and resource
    elements are now called readProfiles and allProfiles and contain
    profile names rather than DB roles.  In the unlikely case you're
    using this feature, you'd have to change the RDs.

	* You can no longer map db profile "roles" to actual profile names in
	  the gavorc [profiles] section.  If you actually need this, try
	  symbolic links to the profile files.


Version 0.7 (2012-01-12)

  * Automatic dependency management for published resources (register and
    adql).  You must run 
    
      gavo imp --system //services upgrade_0.6.3_0.7

   after the update.

  * UWS job representation in the database changed.  You must remove all
    UWS jobs before upgrading.  After upgrading, run

      gavo imp //uws upgrade_0.6.3_0.7
      gavo imp --system //tap createJobTable

    You can ignore error messages during the first of those commands.
