Version 2.5.x

• output values:
  QGIS SMS output linux: new time step TS was not properly written on a new line.
  Therefore SMS and QGIS were not able to detect all time steps
• bufix in implementation of 'tau_erosion_start' for multi grain simulations (full support)

• output values:
  crash of Basement prevented in case of output values that cannot be generated due to missing simulation blocks.
  Now the Parser/GUI throws  an error message in case of missing simulation blocks.
  
• gate formula:
  - correction of discharge calculation
  - added possibility of dynamic calculation of weir coefficient 'mu'
  - added possibility of taking into account backwater effects (only inner boundary conditions and dynamic 'mu')
• tag 'tau_erosion_start' available for multi grain simulations
• improved ascii and vtk output files for vector data, vector components are not written seperately anymore
• removed output format "qgis" (deprecated). QGIS plugin crayfish can now read the file format standard of sms (*.sol).

• improved correction of the overdraft cells (including WARNING in case of failed correction)
• output files changed for combined time histories: nd,el,sd in filename
• headers in output files: matching the value names of the input parser, adding the units
• .sol file readable again

See subsystems for new features.

• Minor fixes to HECRAS-BASEMENT conversion script

• New INITIAL block for 1D morphological simulations introduced
  
• SOURCE block for 1D morphological simulations moved from BEDLOAD to MORPHOLOGY block
• Renamed tag ‘theta_critic’ to ‘theta_critical’ in PARAMETER block in BEDLOAD block for 2D morphological simulations

Attention: The changes of the command file structure are not backwards compatible! Input files for v2.4 will not work with v2.5 and vice versa. We recommend all users to
update to version 2.5.

• Additional monitoring output added: mean cross section bottom elevation
• Monitoring output for multiple cross-sections can now be written to a single file
• Modification of sediment discharge source (additional checks in case of sediment sink, print volumes to file)
• Added tag 'use_energy_slope' (on/off) for sediment transport formula of ‘smartjaeggi’ and ‘smartjaeggi_multi’ for the calculation of the slope
  

• Fixed and improved 'start_time' parameter, which allows for starting a simulation at times different from 0.0
• Removed debug-message indicating too high sediment fluxes

• New inner hQ-boundary added (e.g. to simulate culverts, pipes, bridges). 
• New dredge source added. Sediment can be dredged to prevent sediment deposits from exceeding a specified bed-level. The sediment also can be redistributed at a downstream location (allowing for sediment continuity at inner boundary conditions).
  
• Added second bed-load flux computation method (it is recommended to use the old version with averaged bed-load fluxes, rather internal parameter)
• Added special output of 'sediment grid' as shape file (enables visualizations of hydraulic + sediment grids in GIS)
• Added tag 'scale_lateral_transport' for lateral_transport in order to define only a rotation or a rotation with increased transport
• Additional ‘stringdef_history’ outputs (mean values on a stringdef, approximations): mean[velocity], mean[wse], mean[depth], mean[energy_head], mean[zbed]
  

• Fixed header description for sms output files
• Fixed behaviour of 'dynamical_depth_solver'. Previous implementation led to violation of well-balancing
• Fixed VTK output: vtk does not allow for same variable names in scalar and vector data; resolved by new naming scheme
• Bux fix for sediment restart with cgns (Windows)
• Improved and more user friendly concept for considering bedforms
