TraCI
In the python client, function vehicle.getLeader can now optionally return the pair ("", -1) instead of 'None' if no leader is found. The new behavior can be enabled by calling function traci.setLegacyGetLeader(False). In later versions this will be the default behavior. The return value 'None' is deprecated. Issue #7013
The function 'libsumo.vehicle.getNextStops' now returns a list of StopData objects rather than a list of tuples (the same result type returned by getStops) but different from the return type of 'traci.vehicle.getNextStops'. If the python script should be fully compatible between traci and libsumo, the new function 'vehicle.getStops' must be used.
Tools

Added option --weights.priority-factor FLOAT to factor the priority of edges into the routing decision with a configurable weight (edges with higher priority are preferred increasingly when setting this to a higher value). Issue #6812
supports loading multiple data intervals. Data aggregation can be customized using options --begin, --end, --interval
supports loading multiple files (routes, edgedata, turns). The corresponding options were renamed accordingly (--route-files, --edgedata-files, --turn-files)
supports optimization by linear programming using option --optimize INT|full (requires scipy). The integer argument can be used to configure the maximum deviation from the input route distribution.
supports output of mismatch between measured counts and sampled counts for visualization in sumo-gui via edgeData and edgeRelation files using option --mismatch-output
supports direct optimization of route input (without resampling) by setting option --optimize-input
supports multi-edge counting data using <edgeRelation from="A" to="D" via="B C" count="INT"/>. Issue #6729
supports non-consecutive edgeRelations with maximum gap by using the new option --turn-max-gap . Issue #6726
supports loading origin-destination relations with the new option --od-files. Issue #6888
supports writing results with routeIDs, routeDistribution and flows instead of vehicles. Issue #6730
The turn-file format used by jtrrouter is now deprecated. Instead the new edgeRelation-file format should be used. To convert old files into the new format, the tool turnFile2EdgeRelations.py can be used. The tools jtcrouter.py and routeSampler.py will only accept the new file format as input.

Signal references from OpenDRIVE networks are now exported as a mapping from sumo-tls-link-index to OpenDRIVE-signal-id instead of sumo-edge to OpenDRIVE-signal-name. Issue #6863
netedit
supermode hotkeys changed
F2: Network mode
F3: Demand mode
F4: Data mode

Dead-end links in the middle of a road are now colored in magenta to highlight connectivity problems. Issue #6391
Vehicles that stop (with a <stop>) in the middle of the road now activate emergency blinkers. Issue #6608
netedit
Stacked vehicles (overlapping due to similar departPos) are now indicated by a number. Issue #6485
Stacked vehicles can now be "unstacked" by setting the option 'spread vehicles'. This spreads them alonger the lane sorted by depart time. Issue #5602
Flows are now distinguished from individual vehicles with a text caption. Issue #6486

jtrrouter
Added option --sources-are-sinks (shortcut -S). When this option is set, all flows will terminate upon reaching the from-edge of another flow. Issue #6601
Added option --discount-sources (shortcut -D). When this option is set, the flow departing at an edge will be reduced by the amount of traffic that has reached this edge from upstream flows. When combined with option --sources-are-sinks, upstream flows will terminate at a downstream edge when the source flow number has been reached. This can be used to build a scenario from flow counts at arbitrary locations. Issue #6601
TraCI / Libsumo
Added context subscription filter that filters in a given range around the vehicles route 'addSubscriptionFilterLateralDistance'. Issue #6287
Added new tool jtcrouter.py to build a traffic demand scenario based on turn-count data (this uses jtrrouter in the background). Issue #6229
Added new tool routeSampler.py to build a traffic demand scenario based on turn-count and edge-count data. This tool samples from a given set of routes to meet the detected counts. Issue #6616
the settings file no longer accepts the element breakpoints-file (command line option is still there)
renamed attributes in the settings (breakpoint.value to breakpoint.time and decal.filename to decal.file)
Default settings values 'show link junction index' and 'show link tls index' changed because their interpretation varies after #6376. Old GUI-setting files must be updated to achieve the default look.
