Grasshopper 0.8.0060 available for download

Dear Users and Userettes,

Grasshopper 0.8.0060 is available for download from the usual location. This is a bit of an experimental release, so if you're on a tight schedule you should stay away for a few days in case nasty bugs do turn up.

The installer for 0.8.0052 can be downloaded directly from our servers in case you need to revert.

Old files should open fine, but you might not be able to open files saved with 0.8.0060 on earlier versions!

Major changes explained:

1. Grasshopper can now serialize Curves, Meshes and Breps directly inside the gh/ghx file, meaning you can store this geometry inside parameters as opposed to merely referencing them from a Rhino document. You can 'internalise' referenced and generated geometry via the [Internalise Data] item in geometry parameter menus. Also, while picking geometry from the Rhino document, you can switch modes between [Reference] and [Copy]. [Reference] does the same as before, [Copy] will store a duplicate of the picked shape.
2. Variable Parameters can now be controlled by zooming in on the component in question. This new ZUI (Zoomable User Interface) replaces the old GUI which consisted of a pop-up window that was awkward to use to say the least. In the wake of this new ZUI some of the components that used to have variable parameters have been improved as well (Merge, Sort and Explode Tree most notably), but note that when opening old files you'll still get the old components with the old GUI.
3. Due to sinister and magic incantations by our .NET SDK head honcho it should now be possible to run on Rhino4 without the new Microsoft runtimes. If this is not the case, we'd like to know.

Detailed list of changes since 0.8.0052:

• It is now possible to zoom in on the canvas to 5000% instead of 1000%.
• The middle mouse button no longer deselects anything when it pops up the radial menu.
• Rotation transform formatting now includes axes descriptions in case of orthogonal axes.
• Exported Help topics would have an incorrect HTML header, this is fixed.
• Catenaries wouldn't solve correctly when distance between end-points was large, this is fixed.
• Unsolved catenaries would result in a triangle chain with incorrect length, this is fixed.
