+Older JDK versions are *not supported*. Please refer to an older version of this lib, if you  are interested in using it with an older JDK (with `--enable-preview`). Older versions will not receive patches or any kind of support, though!
 
 We attempt to support libfuse 3.x on Linux and Windows while also remaining compatible with libfuse 2.x on macOS, leading to some compromises in the API.
