# --- Release Notes for Carla 1.9.x --- 0. THIS IS A BETA RELEASE! 1. LADISH does not support multi-client JACK applications. To prevent any issues Carla will switch to single-client mode automatically. 2. Rack mode is still a bit experimental, specially on non-JACK drivers. 3. Carla will not work with non-native LV2 Plugin UIs that require the instance-data extension. This is by design and not a bug. 4. OSC control seems to work well, but has not been tested in great detail. Be sure to report any issues. 5. LinuxSampler (used for GIG and SFZ file loading) and ZynAddSubFX internal plugin is not available for Windows at this point. 6. Carla-Control is not available at this point (needs to be reworked for the 2.0 codebase).
