Release Notes

visioncortex/visioncortex (visioncortex)

v0.9.0

• Added the polypartition module: polygon triangulation (ear-clipping,
  monotone, optimal dynamic programming) and hole removal, ported from
  PolyPartition by Ivan Fratric
• Made SubdivideSmooth public and added open-path (open polyline) variants of
  find_corners, find_splice_points, and subdivide_keep_corners;
  fit_points_with_bezier now takes a configurable max_error (closed-path
  behaviour unchanged)
• Breaking: color_clusters::Builder, BuilderImpl, and
  IncrementalBuilder are now generic over their four closure types instead of
  storing Box<dyn Fn>, so the hot same/diff closures are monomorphised and
  inlined
• Breaking: the deepen/hollow closures now receive &ClustersView
  instead of &BuilderImpl
• Breaking: color_clusters::Builder is now a type-state builder — every
  closure must be set before run()/start(), which is now enforced at compile
  time instead of panicking at runtime

Artifact update for visioncortex resolved to version 0.9.1, which is a pending version that has not yet passed the Minimum Release Age threshold.
Renovate was attempting to update to 0.9.0
This is (likely) not a bug in Renovate, but due to the way your project pins dependencies, _and_ how Renovate calls your package manager to update them.
Until Renovate supports specifying an exact update to your package manager (https://github.com/renovatebot/renovate/issues/41624), it is recommended to directly pin your dependencies (with `rangeStrategy=pin` for apps, or `rangeStrategy=widen` for libraries)
