SaVoir V4.2.8 (12/07/2010)

New features
1	New geometry engine allows to cope with AOIs Areas of Interest with holes also for binary operations like Union, Intersection and Difference.
2	The new capability to handle regions with holes allows to solve an old problem in the optimization algorithm that led to incorrect results when chaining optimization calculation.
3	New feature to combine Direct Downlink with AOI Area Of Interest intersection. Now you can add a Direct Downlink constraint on a Sensor, providing the association between the sensor and one or more Antennas. Acquisitions for that sensor will be planned such that they can be sensed and down linked simultaneously to the selected Antenna.
4	New feature allows to define style defaults. For example, when creating new AOIs Areas of Interest with the AOI Area Of Interest tools SaVoir used to select the default style, which led to regions filled with a transparent color. With the default style the user may select a preference, so that e.g. a new AOI will be drawn only with its border unfilled. Default styles are selected in Edit / Properties...
Fixed source
1	Fixed the configuration of the Max Epoch Age parameter, which provides a threshold of days to declare TLEs Two Line Elements sets as old. The parameter is set to 7 days by default. Before, due to a bug, the parameter was not modifiable. Now it is possible to set other thresholds.
2	Fixed: Zoom to a satellite. Double-click an area and the zoom is stuck on the satellite.
3	Fixed: the optimization with continuous steering sensors (e.g. SPOT) had a fault whereby the AOIs Areas of Interest generated during the algorithm progress were not correctly build leading to some incorrect results, like for example acquisitions starting too early or even not intersecting the original AOI Area Of Interest.
4	Fixed scenario pane to avoid fastidious cursor repositioning to top of tree that occurred often when selecting regions or sensors.
5	Improved progress information when doing Optimization. Before SaVoir did not report well to the user the current status of Optimization, giving the impression that long duration searches would last forever.
