v2026.1.0-rc2

This second pre-release for v2026.1.0 adds a QGIS plotting pane with water balance and fractional flow plots, a new Observation node, and allocation control for the TabulatedRatingCurve.
We fully switched from Arrow to NetCDF-based I/O, and have a new set of icons for our nodes.

Breaking changes: Arrow support was removed and NetCDF is now the only format for results.
model.to_fews was removed. The Ribasim QGIS plugin now requires QGIS 3.40 or newer.

v2026.1.0-rc1

This is the first pre-release running up to the stable v2026.1.0 release.
It is a release candidate, and we recommend most users to stick with v2025.6.0 for now.
We expect to make more breaking changes and add features before the final release.
This release sees significant performance increases for the core as well as the QGIS plugin, which especially help large models.
Route priority in allocation was added to steer the path taken by allocated water.

Breaking changes: In the Node table, source_priority has been renamed to route_priority, and the optional active column was removed.
Note that Ribasim Python will migrate existing models automatically, see also the new guide on updating Ribasim.
If nodes where set to inactive, they will have to be removed manually first.
The ribasim executable was moved to the bin subfolder, so users may need to update their PATH or RIBASIM_EXE environment variables.

Added

• Add Windows installation script. #2682
• Add ResidenceTime tracer. #2701
• Add allocation route priorities. #2731
• Document control by allocation. #2698

Full Changelog: v2025.6.0...v2026.1.0-rc1

v2025.6.0

This release brings significant improvements to the QGIS plugin, allocation, and CLI latency. The QGIS plugin is now published in the QGIS plugin repository and has a simplified UI; you can drag a TOML to QGIS to open a model. The black screen in the iMOD plugin is fixed in the latest version of the iMOD plugin, and the Arrow errors on loading results are also fixed.

Iteratively working on a model in a Python session has become easier now that model.<node_type>.add can replace existing nodes, and run_ribasim(toml_path) shows you live progress in all editors.

Breaking changes: There are two changes that shouldn't be breaking but might affect some users nonetheless. The input_dir default has been changed to "input". Python models now forbid any extra values in schema validation for stricter data integrity.

Added

• Add run_ribasim(toml_path) convenience function. #2653
• Allow replacing nodes with add API. #2664
• Flow communication between primary and secondary networks. #2556
• Read NetCDF files with demand_priority. #2604

v2025.5.0

This release focuses on improving allocation capabilities and performance optimizations.
We linearize the optimization problem, and Pump and Outlets can now listen to allocation to set the flow rate.
NetCDF output has been added, as well as experimental support for NetCDF input.
DiscreteControl now supports an upper and lower threshold to model hysteresis.
Editing models in QGIS is no longer supported; the plugin widget has been reduced one button.

Lastly, Ribasim is now multithreaded!

Breaking changes: In the DiscreteControl / condition table, greater_than has been renamed to threshold_high, and the optional threshold_low column was added.
The surface_runoff column was added to Basin / static and Basin / time.

Full Changelog: v2025.2.0...v2025.3.0

v2025.2.0

In this release, time is of the essence. We now support dynamic Pumps and Outlets, as well as DiscreteControl thresholds.
For each node, timeseries can be marked as cyclic, such that yearly recurring timeseries can be easily used without repetition.
We also developed tools to compare model input in Python.

The most visible change is the renaming of Edge to Link. Like always, existing models are migrated to the new version by reading them with Ribasim Python, and writing out the updated version. For now in Python model.edge will continue to work to ease the transition.

Added

• Check Model equality in Python. #2057
• Compare two models in Python. #2080
• Support cyclic input timeseries. #2081 #2102
• Time dependent greater_than thresholds in DiscreteControl. #2079
• Validation error on connector nodes having the same from and to Basin. #2112
• Support time dependent Pump and Outlet tables. #2110

Changed

• Edges are now called links. #2023
• All geometries are coerced to 2D. #2111

Fixed

• Faster initialization of large tables. #2026
• Declare incompatibility with Pandera v0.23+. #2120

Full Changelog: v2024.11.0...v2025.1.0

v2024.11.0

This major new release contains many improvements. A new formulation allows much smaller water balance errors, which is combined with several performance improvements. Ribasim Python does more validation that was previously only done in the core. The Ribasim QGIS plugin now sets the relations between tables for easier model inspection. Adding min_upstream_level and max_downstream_level to Pump and Outlet means DiscreteControl is often no longer needed.

The most significant breaking change is making the node_id and edge_id the index of the Node and Edge table; these need to be globally unique.

Starting from this release Ribasim is labeled as beta software. Since development is currently mainly driven by applications in the Dutch water system, we expect that addition work needs to be done for general use outside the Netherlands.

For coupled simulation with MODFLOW and/or MetaSWAP, this release is part of the iMOD Coupler, specifically release v2024.4.0
