In the plugin’s page says:
Fully supported in 7.0.0 or higher (including Sage). Support for 6.4.0 and higher can easily be added by updating the Roots_Wrapping class and filters. See the FAQ for details.
but looks like the last update was back in 2015, so was wondering if this is compatible with Sage 9? has anyone tested this with Sage 9 beta?
