This release contains the legacy version of OBS Blade (2.1.0) which was the last working version for OBS 27.X and WebSocket 4.X
If for whatever reasons you can't upgrade the OBS or the WebSocket plugin, this release might be useful for you. For all other ocassions, please just download the app from the App Store (most recent production version) or build it yourself (instructions in the readme).
