Blue Cat Audio has updated the Parametr'EQ series to v. 3.1, which provides several bug fixes and improvements.

The Parametr'EQ series, which consists of Parametr'EQ ($69), Stereo Parametr'EQ ($79), and Widening Parametr'EQ ($87), offers non-linear modeling capabilities.

The upgrade is free for v. 3.0 users and delivers the following improvements: enlarged frequency ranges, better skin GUI (sliders are color-coded to match the corresponding channels), knobs display the disabled state image, and parameters are restored when loading a project in some hosts.
