Karelia Software has released Watson 1.6, a free upgrade to its Web services interface.

It introduces a number of improvements, including integration with iCal and Address Book, alongside support for EyeTV.

The EyeTV support means US Mac users with El Gato Software's EyeTV Digital Video Recorder can select a TV show for recording to disc from within Watson.

Developer and company president Dan Wood explained: "We received many requests for integration with other applications – so we improved the phone, TV and Movie plug-ins to transfer their Web-based data directly into our users' working environments."

Additional features include: wide-screen movie trailer playback within the Movies tool, and numerous bug fixes.

A demo version is available for download – registration costs $29.
