ExpressionEngine 3 will be at end-of-life on December 14th, 2018. Therefore, all BoldMinded add-ons will no longer be supported in EE3.
Many add-on developers, including myself, continued supporting EE2 for several months to a year or more after EE3 was released to help customers during the migration process, however, migrating from EE3 to EE4 is trivial. If your site is running on EE3, there is little to no reason to not upgrade it to EE4 right now. As such, our add-on support will end at the same time EE3 becomes retired software.
