 - If you were using **the old API** (PreReleases, dated Feb 2019) and do not want to update your sketch, download the [1.1.0 library](https://github.com/cansik/realsense-processing/releases/tag/1.1.0) from the releases and [install it manually](https://github.com/processing/processing/wiki/How-to-Install-a-Contributed-Library#manual-install) into your processing library folder.
+- It is not recommended to kill a sketch in processing, without closing the camera.
 - Currently the library is still under development.
 - `Linux`, `MacOS` and `Windows` binaries (x86 / x64) are already bundled into the Jar file.
