1.3.0

Added

• [INPUT] Parameter departure_time_interval can be used to define how accurately utility functions
  are computed for departure-time choice.

Changed

• [DEV] Update deprecated GitHub actions.

Fixed

• [INPUT] The warning message for forced releases now show the proper user id of the agent and edge
  (the internal index was used instead).
• [USER] Fix a crash when a vehicle headway is not a round value.
• [USER] Return error code 1 when the simulation failed (success code 0 was returned).

1.2.0

Added

• [INPUT] Allow edges to have time-varying bottleneck flows with bottleneck_flows and
  bottleneck_times variables.
• [DEV] Add GNU General Public License v3.

Changed

• [INPUT] Arbitrary ids can be used for all input values (negative integers, strings).
• [DEV] Rename the repository from Metrolib to Metropolis-Core.
• [DEV] Update README.md.

Removed

• [USER] Remove the Tauri GUI (not useful and hard to maintain).

1.0.0-rc.1

Added

• [USER] Prototype GUI for METROPOLIS2 with the binary metropolis_gui.
• [INPUT] The paths to the input files and the output directory are set in the parameters JSON file.
• [INPUT] Custom vehicle ids can be used (instead of vehicle indices numbered from 0 to n - 1).
• [INPUT] Add the max_iterations parameter in the simulation parameters to limit the number of
  iterations.

Changed

• [USER] The command-line interface only takes the path to the parameters JSON file as argument.
• [INPUT] The population and network input files accept the Parquet and CSV format instead of JSON.
• [INPUT] The road-network conditions input file accept the Parquet and CSV format instead of JSON.
• [INPUT] The road-network parameters are no longer nested in the network parameters.
• [OUTPUT] Use more interesting variables in the report HTML file.
• [OUTPUT] Use the new terminology in the report HTML file.
• [OUTPUT] The road-network conditions output files are saved in Parquet or CSV format instead of
  JSON (according to saving_format parameter).

Removed

• [INPUT] Stopping criteria can no longer be used in the parameters (use max_iterations parameter
  value instead).

0.8.0

Added

• [INPUT] Add the ExponentialUnadjusted learning model (exponential model with no adjustment for
  the first iteration).
• [INPUT] Add option to force the route to be taken for road legs (parameter route of a road leg).
• [INPUT] Add option to set the speed at which the holes / free space left by vehicles leaving a
  road propagate backward (road-network parameter backward_wave_speed, default is infinite speed).
• [INPUT] Add option to remove the inflow constraint on edges (road-network parameter
  constrain_inflow, default is to constrain both inflows and outflows).
• [OUTPUT] Add the root mean squared difference of departure time in the iteration results.
• [OUTPUT] Add the root mean squared difference between simulated and expected travel time in the
  iteration results.
• [OUTPUT] Add the simulated and expected road-network weights RMSE (root mean squared difference)
  in the iteration results.
• [OUTPUT] Add the length of the route that is new compared to the previous iteration in the
  leg-level results.
• [OUTPUT] Add the departure time shift compared to the previous iteration in the trip-level and
  leg-level results.
• [OUTPUT] Add a boolean indicator indicating if an agent shifted mode compared to the previous
  iteration.
• [USER] Add a warning when deserializing a road network with parallel edges.

Changed

• [INPUT] For the Exponential learning model, the alpha value is no longer nested in a
  structure.
• [INPUT] Road edge's lane number can take non-integer values.
• [USER] For the Exponential learning model, the alpha value represents the weight of the
  simulated weights (previously, it was the expected weights).
• [USER] For speed-density functions, the travel time of a vehicle on an edge is based on the
  density before the vehicle enters the edge (i.e., not the density including the vehicle's own
  length as it was done previously).
• [USER] The departure-time stop criterion only considers the agents who did not switch to another
  mode (breaking change: the default value to use in case of mode switch is no longer required).
• [DEV] Run schemas generation with dev profile to reduce compile time.
• [DEV] Lints are configured directly in Cargo.toml, using Rust 1.74.0.
• [DEV] Road-network weights only store the weights of the edges which are accessible by the
  vehicle.

Fixed

• [OUTPUT] Fix a crash when running metropolis with an output directory that does not exist.
• [OUTPUT] Fix number of decimals for road-network weights RMSE in the report HTML file.
• [DEV] Fix nodes being duplicated when a graph is deserialized.
• [DEV] Fix crash when using a uniform random value equal to 1.0.

Removed

• [USER] The book and API documentation are not longer part of the released zipfile.
