In Iguana 4.0, client executables have been renamed plugins. A new plugin settings page enables you to change the port at which the plugin server listens:

This page also reports any problems with the connection to this port.

In Iguana 4.0, the plugin library uses a multi-threading model. This means that multiple plugins can now run concurrently, and an individual plugin can run multiple concurrent plugin instances.

Existing multi-instance plugins that were written to use the single-threaded plugin library may need to be modified to ensure that the event handlers are thread-safe.

For more information on plugins:

• See Plugin Settings for details on configuring the plugin settings.
• See From Plugin for more information on using a plugin as the source component of a channel.
• See To Plugin for more information on using a plugin as the destination component of a channel.
• See Monitoring Plugin Output for information on how you can monitor the output of your plugin from Iguana.
