   • 32-bit builds on RHEL6
   • 64-bit builds on RHEL6
   • 64-bit builds on REDHAWK6
2. improved error message in case of missing license
3. color legend placement and movement in animation windows improved
4. new function in arithmetic expressions: noise(x,T) (see documentation)

cosin graphical user interface (GUI)

1. fix: ‚open recent‘ menu
2. old-style file selection box called from command-line replaced by OS-specific standard solution
3. about window made visible under all circumstances
4. design and layout of small message windows when called from GUI or application unified and simplified
5. immediate display of files in cosin launch-pad buttons if recently opened/added introduced
6. improved info message when emulated cosin version is used
7. application window placement made more consistent

FTire/core

1. fix: potentially misleading warning message in case of suboptimal pre-processing, in verbose mode
2. specification of more than 9 color palettes supported now in tir-files
3. new TPMS signals: longitudinal and lateral strain
4. new animation model for NPT tire introduced, displaying the spokes
5. made sure color legend is shown for gray-scale footprints
6. made sure measured footprint image is properly resized according to animation window resize
7. made sure optional road file is recognized in statics computation
8. made TYDEX signal ‚tire deflection‘ available in FTire speed modes less or equal 6
9. message in case of superfluous weight parameter in FTire data file introduced
10. radial plastic rim deformation threshold value now allowed to be different for outboard and inboard rim side
11. tire size string now edit-able in cosin/tools, including selection of predefined ETRTO metric or inch notation

FTire/sim

1. improved window sizes and widget placements during interactive simulations

FTire/fit

1. fix: footprints boundary comparison if tire data file contains non-trivial tread pattern
2. fix: animation window in interactive cleat test simulations occasionally was hidden behind FTire/fit window
3. fix: potential crash of GUI window after selecting initial FTire data file
4. fix: static load-case result display in FTire/calc
5. bmp image files in folder meas of old FTire/fit projects are backed up in meas_bkp for optional re-check in
6. improved slider specification for interactive cleat tests
7. made GUI-based control desk selection in FTire/fit observed also by interactive cleat tests
8. made tire size string as used in FTire/fit report edit-able

FTire/hilac

1. added support for Simulation Workbench 2022.2
2. changed default Simulation Workbench version to 2020.2
3. rotational damping in case of steering motion input in ftdwt reactivated

cosin/road

1. fix: occasional fail of length unit heuristics for old ASCII format rgr data
2. fix: occasional fail of password query for pw-protected rgr files
3. new fast center-line evaluation in higher speed modes
4. definition and evaluation of ‚water puddles‘ for hydro-planing simulations

cosin/tools

1. automatic switch between FTire and cosin/mbs settings (predefined search strings) in cosin/ip
2. prevent cosin/ip from occasional hanging when browsing too fast
3. space-saving compression of formula-based roads if obstacle geometry is independent on x

cosin/tools for roads

1. fix: potential issue in road generator when setting height constant along x-axis
2. fix: made sure friction values are correctly inserted when reformatting old ASCII rgr files
3. fix: make fast rgr reformatting work if center-line data are not read from rgr-file, but from extra center-line file
4. accelerated obstacle creation of obstacles not depending on x (like ruts)
5. new cosin/tools function: show road height profile along given general curve in x/y plane
6. new feature ‚puddles‘ in road builder for hydro-planing model
7. new obstacle types in road builder: irregular ruts, dry or water-filled
8. new single obstacles in road builder:
   • elliptical pothole
   • circular puddle
   • rectangular puddle
9. integration of puddles in road visualizer

cosin/tools for tires

1. fix: fingerprint comparison to other emulated versions
2. fix: column width of Numerical Settings table to fit on one page
3. fix: made sure speed mode is always shown correctly in GUI
4. all outdated Pacejka Magic Formula variants besides Pacejka 2002 no longer supported
5. full integration of NPT tire in GUI
6. made sure apparently corrupted tire database is not used
7. new example FTire data file in cosin/io format
8. new npt.tir example data file

CTI (cosin tire interface)

1. fix: made sure selected prefix in CTI is not partially disregarded
2. fix: potentially incomplete message output when computeForcesList function is used
3. fix: potential dysfunction of sliders in ctiQuarterCar simulations

Documentation

1. documentation completed for NPT tires
