**Dynamic Waters 13.1.0**

Dynamic Waters now supports three versions:** NeoForge 1.21.1, Fabric 1.21.1, and Forge 1.20.1. The Fabric and Forge builds are new, so please report any issues you encounter.

New Features
- River Islands: Lowland rivers can now split into two or three channels around small islands before joining together again.
- Fallen Logs: Fallen tree trunks can now appear across the water between river islands, using wood types from nearby trees.
- Ice Floes: Groups of thin ice floes now drift downstream along open mountain rivers in cold regions, including over waterfalls. They cannot be stood on and can be broken by hand.
- Mountain River Ice: Added new configuration options for mountain river freezing: never freeze, freeze only on calm stretches (default), or freeze completely, including waterfalls.
- Mountain River Biome: Mountain river channels now correctly receive the river biome, or Frozen River in cold regions.
- Delta Inland Reach: Added a configuration option controlling how far inland a delta can begin. Default: 256 blocks. Set to 0 to disable deltas.

Mod Compatibility
- Valkyrien Skies (Forge 1.20.1): Ships floating on rivers are now affected by river currents.
- Renamed the ship current speed option to Physics Ship Flow Speed. It now supports both Sable and Valkyrien Skies. Set it to 0 to disable currents affecting ships. Existing configuration values are preserved.

Fixes
- Fixed river mob spawning on NeoForge. Moving river water now correctly uses the spawn settings of the river biome, which previously were not applied.
- Fixed deltas generating across rivers or creating short, disconnected channels. Main delta channels now properly reach the sea.
- Fixed extremely large canyons generating when rivers were routed over terrain ridges.
- Fixed rivers ending incorrectly at narrow entrances to dead-end lakes.
- Fixed lake rims flooding when rivers flow at the same elevation as the lake.
- Improved tributary connections to main rivers, eliminating unnatural bends and spikes at confluences.
- Fixed rivers getting stuck in endless loops at region borders. They now properly terminate in lakes.
- Fixed ravines incorrectly connecting to rivers at their dry starting points.
- Fixed incorrect current behavior at the headwaters of rivers fed by other rivers
