Dear All,

a new version of Grasshopper is available for download from the usual location. This release contains a fair amount of bug fixes and new features. We recommend not updating immediately if you're in the middle of a project or nearing a deadline, there may be new bugs in this release.

New features:

• Added [Point Deform] component for changing the control-point locations of geometry (Transform.Morph dropdown).

• Added [Bend Morph] component for bending geometry from lines to arcs (Transform.Morph dropdown).

• Added component menu option to the [Entwine] component for grafting (instead of flattening) inputs.

• Added [Move Away From] component for moving geometry away from other geometry (Transform.Euclidean dropdown).

• Added Enable Solver UI to last chance autosave recovery window.

• Added Peak Display to the Galapagos Fitness Landscape component.

• Added Feature Display to the Galapagos Fitness Landscape component.

• Added Slope Display to the Galapagos Fitness Landscape component.

• Added Direction Display to the Galapagos Fitness Landscape component.

• Added Remap Option to the Galapagos Fitness Landscape component.

• Added contour accuracy options to Galapagos Fitness Landscape component.

• Added [Smooth Numbers] component for interpolating numbers over time (Maths.Util dropdown).

• Added [Right Trigonometry] component for solving right triangles (Maths.Trig dropdown).

• Added [Triangle Trigonometry] component for solving generic triangles (Maths.Trig dropdown).

• Added [Centroid] component for finding triangle centroids and medians (Maths.Trig dropdown).

• Added [CircumCentre] component for finding triangle circumcentres and perpendiculars (Maths.Trig dropdown).

• Added [InCentre] component for finding triangle incentres and angle bisectors (Maths.Trig dropdown).

• Added [Orthocentre] component for finding triangle orthocentres and altitudes (Maths.Trig dropdown).

• Added [Curve Side] component for determine on which side a curve a point lies (Curve.Analysis dropdown).

• Added [Plane Region] component for finding convex regions bounded by planes (Intersect.Mathematical dropdown).

• Added [Point Deform] component for modifying geometry via control-points (Transform.Morph dropdown).

• Dragging individual components/parameters will now snap to horizontal wires.

Bug fixes:

• Using MRU tiles would always open the GH file on the main canvas, this is fixed.

• Canvas redraws would not work correctly if more than one canvas was active, this is fixed.

• Instantiating components using double-click would always insert the component on the main canvas, this is fixed.

• Drag and drop did not work by default for canvas instances, this is fixed.

• Cull Vertices component would sometimes fail due to index out of range errors, this is fixed.

• The [Arc](Plane, Radius, Angle) component would sometimes result in invalid arcs, this is fixed.

• Additional changes to make Grasshopper compatible with FIPS standards.

• [Surface|Line] intersection component did not correctly re-instate 'Limit First', this is fixed.

• [Surface|Line] component was incorrectly nicknamed SCX (c for curve), this is fixed.

• [Construct Mesh] would crash if topologically invalid faces were supplied, this is fixed.

• [Quadrangulate Mesh] had erroneous tooltip texts, this is fixed.

• The [Smaller Than] component did not handle comparisons with infinities correctly, this is fixed.

• The [Larger Than] component did not handle comparisons with infinities correctly, this is fixed.

• The [Equality] component did not handle comparisons with infinities correctly, this is fixed.

• The [Ellipse] component did not correctly compute focal points for negative radii, this is fixed.

• The [Cone] component did not handle negative radii correctly, this is fixed.

• The [Cone] component sometimes crashed when the radius was zero, this is probably fixed.

• The [Sphere] component did not handle negative radii correctly, this is fixed.

• The [Sphere] component sometimes crashed when the radius was zero, this is probably fixed.

• The [Cylinder] component did not handle negative radii correctly, this is fixed.

• The [Cylinder] component sometimes crashed when the radius was zero, this is probably fixed.

• The [Brep Topology] component did not output correct EF data, this is fixed.

• Integer conversion that exceeded the 32-bit integer range would crash, this is fixed.

• Curve|Plane intersections would return duplicate results on seam intersections, this is fixed.

• Curve|Line intersections would return duplicate results on seam intersections, this is fixed.

• Expressions entered in the Generic Data parameter 'Set Multiple' menu were parsed recursively, this is fixed.

• Changes to the MRU database would not immediately affect the Canvas MRU tiles, this is fixed.

• Groups containing empty subgroups would include (0,0) in their bounds, this is fixed.

• BeforeRunScript override inserts in C# scripts did not include method brackets, this is fixed.

• (Anti)parallel lines were not filtered in the Line|Line intersection component, this is fixed.

• Preview Plane Size setting was named confusingly, this is fixed.

• The [Bounds] component would output a weird domain when all numbers were nulls, this is fixed.

• Opening old GH files with Value Lists would not open with the correct item selected, this is fixed.
