• Added a raster-specific optimized Cython implementation of map_max_of_link_nodes_to_link for improved performance. #2309
• Added a Cython implementation of weighted_mean_of_parallel_links to optimize calculations in the OverlandFlow component. #2310
• Added new validators to check whether values fall within a specified range. #2322
• Added a new validator, require_one_of, to ensure values are contained within a set of allowed values. #2332

• Corrected documentation and parameter naming in DepthDependentLinearDiffuser. #2258

OverlandFlow Improvements

• Refactored imports, fixtures, and internal structure for clarity and reduced memory usage. #2311–2315
• Added multiple Cython optimizations for flow calculations (calc_bates_flow_height, calc_grad_at_link, calc_discharge_at_links, etc.). #2316–2321
• Improved time-stepping logic and error handling. #2323
• Simplified time-step management by removing the _dt attribute. #2324
• Updated field specifications and removed unused code. #2325, #2375

Performance & Infrastructure

• Refactored links_at_node construction from (O(n^2)) to (O(n)). #2333
