+* Disabled GCC optimization that prevents mod dlls from unloading after engine calls dlclose
+* Fixed third party libraries possibly not being linked to when building Linux server dll (Thanks a1batross)
+* Mods made with this SDK will now shut down if they detect they are being run from a Valve game directory (e.g. by placing the dlls in `Half-Life/valve/cl_dlls` and `Half-Life/valve/dlls`). This is not supported and puts users at risk of being VAC banned. Run mods from their intended location only
