v2025.1.0

The first release of 2025 makes the Ribasim core more robust and stable, and speeds up
initialization for large models. The biggest new feature is the experimental support for
calculating tracers in Ribasim directly, which will hopefully make it easier to track where
the water resources are heading.

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
