Older versions of Iguana used a different set of libraries and APIs to interact with plugins. To ensure backward compatibility, these libraries and APIs are still supported, but new plugins should not use these libraries.

	These existing libraries have not been deprecated and are still supported. You do not need to update your plugin to use the new VB.NET/C# plugin interface.

For information on the libraries and APIs that are in current use, see Writing a Plugin in VB.NET or C#.
