- Typo fix to initialEnergy setting (need to update config files using this)

- Fixed window resize issue and using spinner instead of dropdown for zoom
levels; thanks to PJ
- Set of javadoc, style, and other small fixes
Version 1.4.0 (18 Mar 2010)
- Added the possibility for each node having multiple interfaces
* Requires changes to the configuration files, see default_settings.txt
- New/improved routing algorithms
* added parametrization for MaxProp (default alpha=1)
* added Prophet and Maxprop routing algorithm versions that
take timescale as a parameter, and estimate the needed routing algorithm
parameters based on that
* see Karvo and Ott, Time Scales and Delay-Tolerant Routing Protocols,
CHANTS 2008, for more information.
* added new (unrealistic) EpidemicOracleRouter that transfers messages
immediately and deletes all replicas from buffers when the message is
delivered
* added maximum meeting probability set size support for MaxProp to improve
its performance in scenarios with many nodes
- Added MessageReport class for reporting message deliveries,
CreatedMessagesReport for message creations and EventLogReport for
reporting everything (in a StandardEventsReader-compatible format)
- Added application layer
* applications can be created by extending the Application class
* multiple applications can run in the nodes
* report modules can register for application events
* see PingApplication and PingAppReporter for an example
- Added ClusterMovement for creating clusters of nodes and LinearFormation
for lines of nodes
- ExternalMovementReader supports comment lines (starting with "#")
- "Delete all" message event and support for this in StandardEventsReader
- Possibility to choose first route stop for MapRouteMovement
- Added new message event generators: OneFromEachMessageGenerator and
OneToEachMessageGenerator
- Added time range setting to MessageEventGenerator
- GUI improvements
* highlighting of pause-events to EventLogPanel
* GUI starts paused by default
* hh:mm:ss display for simulation time (right-click the simulation time)
- Improved and new analysis scripts
* added "log", "total", and "index" options for the ccdfPlotter.pl
* added getStatsAverages.pl
- Bugfixes
* host range checking in MessageEventGenerator
* command line option -b doesn't require range anymore
Version 1.3.0 (19 Jan 2009)

(types of) modules
- EnergyAwareRouter demonstrating energy awareness possibilities and use of
the ModuleCommunicationBus
- EnergyLevelReport for reporting the energy levels
- ConnectivityONEReport class for generating connectivity traces
that can be read using the StandardEventsReader
- Enhancements
- Any number of input config files supported

- small change in the command line syntax; see README for details
- MessageEventGenerator supports message creation time and destination
host ranges
