# Z/Changes from version 0.9.8 to version 0.9.9

# Changes from version 0.9.7 to version 0.9.8

- All
  - debugged bug 1976405 Saving invalid dump configuration; Was a false encoding in Option_IntVector
  - builds under 64bit Linux (solved bugs bug 1927822, bug 1928370, bug 1930444, bug 1931468, bug 1932961, bug 1933569, bug 1934635; thanks to Ronald Nippold for being persistent in supplying the build logs
  - encapsulated xerces-attributes; makes value retrieval so much more comfortable; retrieve a attribute using attrs.getTYPENAME(id) instead of getTYPENAME(attrs, id)

- Simulation
  - Hidden state loading/saving completely from the microsim
  - Vehicle may now end their route at a certain position of the route's last edge (see Specification)
  - The route may be now given as an attribute (route) within the vehicle definition (see Specification)
  - The vehicle now stores most of its definition parameters in myParameter, not as atomar values
  - Solved problems with multiple stop on same edge and with stops on lanes which can not be used for continuing the route; thanks to Friedemann Wesner and Gerrit Lammert for reporting them
  - Reworked mean data output. The vehicle movements are now weighted by the time the vehicle was on an edge/lane. Additional constraints for output (--exclude-empty-edges/--exclude-empty-lanes) allow to dump only information about edges/lanes which were occupied by vehicles.
  - debugged bug 1964433 different simulation results for different starting times; The issue was a false computation of WAUT switching and TLS offset times when choosing a different simulation begin time than 0
  - replaced MSVehicle::getInTransit and MSVehicle::running by MSVehicle::isOnRoad
  - removed MSEdge::isSource; was used only once and can be easily replaced by comparing the result of MSEdge::getPurpose()
  - debugged bug 1932105 second stop on the same edge confuses vehicles
  - debugged bug 1941846 repeatable crash with sumo r5378
  - debugged bug 1912547 linux 64 bit compile error for sumo svn 5143
  - debugged bug 1913655 command line sumo throws unknown exception
  - debugged bug 1924989 sumo r5186 crashs by pure virtual function call
  - begun work on Specification
    - all vehicles are emitted at position=0, with speed=0
  - removed usage of NLLoadFilter
  - added an option to quit the simulation if a number of vehicles is exceeded (--too-many-vehicles <INT>)
  - fully integrated Tino Morenz's MSVTypeProbe; moved it from microsim/trigger to microsim/output; tests added; a vtypeprobe is now defined within additional files this way: <vtypeprobe id="test1" type="" freq="10" file="vtypeprobe.xml"/> ("test1" is the vehicle type to report, leave empty in order to get information about all vehicles)
  - replaced usage of "Command" by encapsulating methods in "WrappingCommand" wherever possible
  - "debugged" usage of actuated/agentbased tls; should be covered by tests, in fact
  - further work on devices-consolidation
  - implemented a one-shot / multi-shot routing device

- GUISIM
  - Removed opening an additional command line window from the release version
  - Title is now set properly
  - debugged bug 2021454 Discarding View settings resets them; The editor now uses the settings that were used when it was opened as the one to apply when "cancel" is pressed
  - debugged bug 2021464 view settings are not saved; The button is now removed, all the interaction will be done via the top buttons
  - debugged bug 2015792 Save List of selected Items; The proper extension (mostly ".txt") is now appended if no extension is given. Affects saving breakpoints, additional weights, tracked parameter, and selections.
  - bug 1919509 guisim crashed is invalid, the issue was a buggy opengl driver

- NETCONVERT
  - debugged bug 1993928 --keep-edges.input-file does not remove empty nodes; as soon as one edge-removal(keeping) option occures, nodes are rechecked whether they contain any further edge. If not, the node is removed.
  - VISUM-import: debugged failures due to false district node position computation
  - Connection building: made storing outgoing edge connections sane; replaced three strange storages by one
  - Disabled the support for setting an "edge function" - because vehicles are emitted the same (parametrised) way on each edge, we do not need a distinction between source and normal edges; sink edges were never distinguished.
  - Refactored the way edge types are stored in NETCONVERT
  - removed "name" attribute from NBEdge; was not written anyway
  - work on SUMO-networks reimport (unfinished)
  - documentation: debugged bug 1909685 option "omit-corrupt-edges" not recognized (use --dismiss-loading-errors instead of --omit-corrupt-edges)
  - removed usage of NLLoadFilter
  - thanks to Christoph Sommer, the OSM importer now handles speed and lanes information; default OS values are now used, too

- DUAROUTER / JTRROUTER
  - Removed option --move-on-short. It got obsolete as vehicles may start on edges which are shroter than they are, now.

- DUAROUTER
  - debugged bug 1981921 duarouter truncates routes; Now, --remove-loops only prunes the route if the vehicle would have to take a turnaround at the begin or end.
  - reworked handling of broken routes; longer routes are not replaced; incomplete routes may be corrected using the new --repair option

- JTRROUTER
  - Removed possibility to specify turning percentages using CSV files

- DFROUTER
  - Definition of emitters, vss, etc. are now written into the same folder as the declaration

- TraCI
  - TraCI is now enabled as default

- od2trips
  - due to being used for macroscopic demand definitions, OD2TRIPS now emits vehicles using departlane="best" and departspeed="max"
  - removed option to parse list of tables from a vissim file; they may be given at the command line (--vissim is no longer supported)
  - added the possibility to omit writing the vehicle type (--no-vtype)

- Tools/Main
  - added some tools for output visualization (mpl_dump_twoAgainst.py, mpl_tripinfos_twoAgainst.py, mpl_dump_timeline.py) (see Tools/Main#Vizualization_Tools)
