 ## Main
+-   Fix performance for non-contiguous NumPy array conversion in pybind vector converters. This change removes restrictive `py::array::c_style` flags and adds a runtime contiguity check, improving Pandas-to-Open3D conversion speed by up to ~50×. (issue #5250)(PR #7343).
 -   Corrected documentation for Link Open3D in C++ projects (broken links).
 -   Fix DLLs not being found in Python-package. Also prevent PATH from being searched for DLLs, except CUDA (PR #7108)
 -   Fix MSAA sample count not being copied when FilamentView is copied
