TraCI
- added a possibility to access a vehicle's signals, wipers, and other things; see Vehicle Value Retrieval, Change Vehicle State, and Vehicle Signalling
Simulation
- corrected direction when departing at a lane's begin

  - corrected "incoming lanes" determination
  - added the option --lanechange.allow-swap; if enabled, vehicles blocking each other are exchanged
GUI

netconvert

  - parsing maxspeed values given as '50 km/h'; was: defect 344: The TAPAS Cologne scenario does not work with the current(0.12.0) SUMO version - maxspeed not numeric
  - new option --osm.skip-duplicates-check added which, well, skips checks for duplicate nodes and edges
