News:

* EGEE Barcelona'09: DIANE/Ganga succesfully demonstrated
interoperability with SAGA and TeraGrid resources. This opens up the
space for easy use of supercomputers and clouds.

* Default Ganga version is 5.3.5. Any fresh DIANE installation will
automatically fetch the new default Ganga version.

* Web-based monitoring (prototype, not guaranteed to work)
* This website allows you to follow the progress of your tasks.
* It uses ActiveMQ (LCG MSG) system.
* By default the monitoring is ON, to disable look into the config
options.

* Important changes in version 2.0-beta20
* THIS MAY BREAK YOUR SCRIPTS: changed format of vcard.txt to be a
repr of the standard python dictionary. To read-in the file in python,
it's enough to do: vcard = eval(file('vcard.txt').read()). Then
vcard.keys() correspond to different sections, including the Ganga job
identifier if agent was submitted by Ganga. Dropped the old text
format (it was very unhandy anyway).
* configurable and more reasonable default parameters for chunk
file transfer
* now orphaned sessions are declared after 200 seconds for 100K
data chunks - 500b/s transfers
* improvements to <2.4 compatibility code
