	2nd September 2010 Added H10 version of the microbevel Vop to the Vex/Vops page.
	23rd January 2010 Updated all HDK code to work on H10, and compiled 32bit versions for Windows.

	8th March 2009 Added bend light shader otl.
	26th June 2008 Added occlusion light shader otl.
	10th May 2008 Updated UnwrapLSCM to work with H9. Fixed the multi-parameters that were previously still in H8 format.
	30th April 2008 Updated Wrap deformer with some bug fixes, also added support for radius override attribute on the driver surface. Updated the help and added it to the source code package which I had forgotten to do.
	27th April 2008 Added Volume measure sop otl.
	27th April 2008 Fixed Driven obj to work in H9. Updated download pages to add vc7 build info to H9 downloads. Vc8 and 64-bit builds for windows coming soon.
	9th April 2008 Updated multi-parameters in Parents sop and PartitionByCol sop to use the H9 syntax.
	4th April 2008 Replaced the source code for Pointslide sop as it was the wrong version.
	30th March 2008 Made more improvements to the Wrap deformer, wrap prep now adds the orient attribute.
	29th March 2008 Made a number of improvements to the Wrap deformer, it now supports the orient attribute which should make it quicker and means the Wrap prep sop is not required. Also updated the example deformer file to show this new method and fixed the partition example to work with H9.
	8th March 2008 Added duplicate point testing to  RBFmorpher, duplicate feature points cause the sop to fail.
	1st March 2008 Fix bug with SBCdeformer that would cause it to fail if the number of points on input 1 changed.
	1st March 2008 Reversed the order of the recent changes list. Latest stuff is now at the top.....
	28th February 2008 Fixed a bug with new cacheing option of  RBFmorpher  where changing the kernel type was not correctly cached.
	27th February 2008 Fixed pre-convex option of SBC_Capture.
	24th February 2008 Uploaded compiled 9.1 versions of all hdk code.
	23rd February 2008 Improved the accuracy of  RBFmorpher  for large meshes.
	20th February 2008 Added a new RBFmorpher for H9.1 including cache option and extra kernals.
	4th December 2007 Uploaded 3 new otls Carve proximity, Multi carve and Prim sort
	17th November 2007 Several improvements made to Tri2Quad. Some parameters have been renamed so this may not work in old hip files. Posted modified source for all sops that needed code updates to work with H9. Added GroupEdges sop.
	11th November 2007 Added an output group to UVunwrapLSCM - this stores the group of polys that are between the seams as indicated by the hint prim. Fixed a bug with the amplify parameter on UVuniform and made the first changes to support groups. Also changed some defaults to numbers more likely to work every time. Finally added the ability to view the smoothing grid in uv space.
	10th November 2007 Added seam colouring to UVunwrapLSCM - this lets you more easily visualise in uv space which seams match together in 3d. Handy for painting textures if you don't have a 3d paint package.
	4th November 2007 Added support for seams defined by an attribute UVunwrapLSCM
	1st Novemeber 2007 Upped the solver limit for UVunwrapLSCM - should improve the solution in tricky cases

	29th May 2007 Fixed an error in the wrap deform sop where it would wrongly tell you the geometry wasn't captured if a varmap existed on the input geometry. Also added an extra check to unsure rest and deforming capture geometry have the same number of points. Fixed the missing geometry in the example hip file. Added some simply error trapping to measure distortion sop Added variable mapping for the local variables.
	28th May 2007 Added measure distortion sop to hdk page.
	26th May 2007 Modified selector script for highlight so you can now pick the camera in the viewport.
