v0.2.2

Release Notes

Changed

• Improved the code performance by creating a global thread pool that is
  shared across all functions that run in parallel. This avoids creating
  a new thread pool for each function call, which was causing a performance
  overhead.
• Improved the performance of the gaussian_smoothing function by using
  a more efficient algorithm to compute the convolution of the input
  data with a Gaussian kernel.

v0.2.1

Release Notes

Fixed

• Fix the smooth_linestrings function to correctly handle returning
  multiple LineString geometries when a list of LineString geometries
  is passed as input.

v0.2.0

Release Notes

This is a major release with breaking changes. The codebase has been
written from scratch in Rust and the Python bindings have been updated
to reflect the changes in the underlying implementation.

Changed

• The bc_types argument of CatmullRom class has been renamed to
  bc_type and custom boundary conditions have been removed. The
  available boundary conditions are 'natural', 'closed', and
  'clamped'.
• The smooth_linstring function has been renamed to smooth_linestrings.
  This function now handles a list of LineString geometries instead of a
  single geometry. The code runs in parallel in Rust and is significantly
  faster than the previous implementation. If a single LineString geometry is passed a single LineString geometry is returned, otherwise a list of LineString geometries is returned.
• The compute_tangents has been renamed to linestrings_tangent_angles.
  This function now handles a list of LineString geometries and returns
  the tangent angles at each vertex of the input geometries. The code runs
  in parallel in Rust and is significantly faster than the previous. If a single LineString geometry is passed a single array of tangent angles is returned, otherwise a list of arrays is returned.

v0.1.1

Release Notes

Added

• Add a new boundary condition for the CatmullRom class called 'clamped',
  which allows anchoring the first and last points of the curve to the first
  and last control points. This is particularly useful for smoothing
  MultiLineString geometries where the first and last points of each
  line segment must remain connected to the previous and next line segment.

Changed

• Freeze attributes of CatmullRom since they are not supposed to be changed,
  once the class is instantiated. If needed, a new instance should be created.
