Swap COP is not more backwards compatible, and explicitly converts the old style parameters before a save if it has not already been done as a result of a cook.

Fixing bug where it was possible to start up in Never update mode with the update button disabled. This was extremely annoying.

Major changes to the operator preset mechanism. We are still able to load old preset files. All new presets will be saved to "index" files in subdirectories of the presets directory in the HOUDINI_PATH. The Presets menu contains a dynamic list of all available presets instead of requiring a manual search for the correct .preset file. Existing .preset files can easily be packaged into index files using the new hidx command line application.

This new preset mechanism also re-introduces the capability that used to exist with the Make Permanent Defaults menu item. If a preset named "Permanent Defaults" exists for an operator, it will be loaded by any new instances of that operator type.

In terms of hscript command support, there are four new commands. oppresetls lists all available presets. oppresetload loads a preset into an operator. oppresetsave saves an operator's settings as a preset. oppresetrm deletes a preset.
