+## [0.7.0] — 2026-02-26
+
+### Added
+
+- **MoorDyn v2.6.1 mooring integration** — coupled MoorDyn as a Git submodule, enabling catenary and taut mooring analysis. New `MoorDynConfig` struct and `HydroSystem::SetMoorDynConfig()` API for mooring configuration.
+- **MoorDyn force coupling into HydroSystem** — mooring forces from MoorDyn are applied at each timestep alongside hydrostatic, radiation, and excitation forces
+- **RM3 mooring demonstration** — YAML-driven RM3 two-body point absorber with 3-line catenary mooring (6 MoorDyn segments: anchor–clump + clump–fairlead per line), runnable via `run_hydrochrono`
+- **Real-time mooring line visualization** — VSG GUI renders mooring line node positions queried from MoorDyn at each frame, with dynamic tension color mapping (blue-to-red gradient scaled to current tension range)
+- **RM3 mooring verification test** — automated CTest comparison against WEC-Sim/MoorDyn co-simulation reference data for body heave and fairlead tensions (correlation ≈ 0.998, max tension error ≈ 1.8% of mean)
+- **`hydroc/math_constants.h`** — centralised `M_PI` definition replacing scattered per-file definitions
+
+### Changed
+
+- **IRF truncation separated from smoothing and tapering** — `RadiationKernelProcessing` now treats truncation as a distinct step from the smoothing/tapering pipeline
+- **`RegularWave` encapsulation** — members made private with `SetPeriod()`/`SetOmega()` accessors
+
+### Fixed
+
+- **Cross-machine build robustness** — resolved HDF5 target name conflicts and Eigen3 detection issues affecting some build environments
+- **Chrono API and test infrastructure compatibility** — updated for recent Chrono API changes
+
 ## [0.6.0] — 2026-02-19

-> ⚠️ HydroChrono is under active development (`v0.6` prototype). This early release focuses on a YAML‑driven CLI, real-time VSG visualization with animated free-surface rendering, and portable HDF5 outputs so you can try the code and share feedback. Expect rapid iteration over the coming year (inc. more advanced PTO, control, mooring & hydrodynamics) — please get in touch if you have any issues or feature requests.

 HydroChrono (Hydrodynamics for Project Chrono) is a hydrodynamics simulation toolkit built on [Project Chrono](https://projectchrono.org/). It is designed for simulating wave energy converters (WECs) and other complex ocean systems, and is **100% free and open‑source** end‑to‑end — no proprietary dependencies required. This repo ships a prototype, YAML‑driven CLI app for running simulations and exporting portable results.
