hkey now supports http proxies when connecting to license.sidefx.com. It saves these proxy settings in a preference file called hkey.pref.

Removed a reference to freed memory when quitting Houdini with the tool menu up in the viewport. I don't think that this was causing any real problems, but definitely not a safe operation.

Render state now properly handles viewport resizing.

Adding a script to the toolkit binaries to extract the HDK header files.

Fixing a bug where hcbrowse won't run on Linux machines with FireGL cards.

Ray-tracing of large numbers of metaballs has been sped up considerably. As well, accuracy of super-quadric metaball intersection has been improved.

The ptlined VEX function is now more precise.

Even if a shader does not have a color parameter of a particular name, the shop will now link the openGL diffuse color to the first color parameter present (if any).

The color rectangles in non-animatable color parameters now support drag'n'drop operations.

Non-animatable parameters can now receive channel values from drag'n'drop events.

Fixed bug where dragging a parameter would actually supply one more chunk of data than the parameter supports.

We no longer ignore the umask when creating directories on unix machines.

On unix, the license server host name is now stored in a file. This way, if hserver is restarted or the machine is rebooted, the same license server host will be used. The SESI_LMHOST environment variable no longer needs to be set.

Fixing a bug where returning multiple licenses in a row would sometimes crash hkey.

When we fail to find a license when running Houdini, we now launch hkey to help the user solve their problems.

Can now drag vops and vopnets directly onto geometry.
