Dear friends and users,
we are happy to announce the release of SUMO version 1.22.0.

)
This release has been long in the making and is filled to the brim with features and fixes. Major features are a full rewrite of the rail simulation code to improve its speed, support deadlock-free train simulation and obtain additional outputs. Electric vehicles can now automatically find a charging station with the new stationfinder device. Many new Python tools were added and older tools upgraded.
We were humbled by the discovery of 2 regressions in the meso simulation which were impacting roundabouts and queue assignment for 5 years without being noticed. Please check whether your meso simulation results were impacted.
There are many more features and fixes in this release and the most important ones are listed below. For a full list of changes, as always see https://sumo.dlr.de/Changelog.
### Enhancements
- sumo
- Added new stationfinder device which reroutes electric vehicles to a chargingStation depending on it's state of charge

- Traffic lights of type actuated can now react to a pedestrian crossing
- personTrip now supports geo-coordinates
- Added option --mapmatch.taz which works similar to --mapmatch.junctions but uses arbitrary TAZ definitions
