A quick patch for County Callouts will be out soon to make the plugin compatible with the latest GTA/RagePluginHook/LSPDFR versions. Soon after that will be an initial preview release of Highway Callouts. It will feature a small handful of calls and features at first launch and be built upon going forward.
My activity should start to increase again now that I have more time available. I have some more projects in the works and hope to have more information to share soon.
