## News

30.04.2026: Release of TFS 1.3.0 (Minor Release);
Release 1.3.0 Highlights

- Updated dependencies to **Modelica Standard Library 4.1.0** and **Complex 4.1.0**.
- Added new **`CentrifugalPump`** model with characteristic-based parameterization and test models.
- Added **`StaticHead`** and **`TankCuboid`** components.
- Improved **OpenModelica/OMEdit compatibility**, especially for `CentrifugalPump` and `SingleSensorSelect`.
- Improved **pressure-drop visualization** for `FlowResistance` and valve components.
- Extended **incompressible media** with additional thermodynamic properties.
- Improved **moist-air media functions**, including `isentropicExponent` and `specificEntropy`.
- Fixed Reynolds-number calculation in **`dp_tau_centrifugal`**.
- Improved NTU heat exchanger documentation and simplified `PartialNTU`.
- Added and updated **Dymola** and **Modelon Impact** metadata.
August 2026: Release of TFS 1.4.0 (Minor Release)

### Release 1.4.0 Highlights

- Added the new **`ThermofluidStream.Idealized`** package for simplified thermodynamic process and cycle modeling.
- Added the new **`ThreeWayValve`** model based on `BasicControlValve`; the previous `Switch` model is now obsolete.
- Substantially improved the **sensor package**, including icons, connector placement, dynamic value displays, numerical formatting and selectable display units.
- Improved **valve diagnostics and validation**, including unreachable-set-point indicators and checks for invalid `dp_ref` and `rho_ref` modifications.
- Deprecated the **`Cvs_UK`** flow-coefficient option while retaining it for compatibility.
- Improved **heat-exchanger** connector handling, icons, assertions and OpenModelica compatibility.
- Improved graphical rendering and cross-tool compatibility of **idealized thermodynamic processes**.
- Updated the **`SimpleAirCycle`** example and several media, pump and heat-exchanger examples.
- Changed the default value of **`Idealized.Processes.Isenthalpic.enforcePressureDrop`** from `true` to `false` to improve numerical robustness.
- Added and updated regression tests and fixed several issues in sensors, valves, heat exchangers, documentation and graphical annotations.
