Among the enhancements, we can mention support for renaming the non-Steam game shortcuts via the Manage Shortcuts options in the Big Picture mode, along with support for fine tuning binding selections for non-Steam game community configurations, thanks to the ability to share them by name.
It is now possible to save legacy configurations for games that have native controller support, the Steam Controller configurator has been updated to better display the title and author of a certain set of bindings, along with their templates, and the configuration selector is now more responsive.
