10.19 release.
Note that for NTSYNC you need a new Linux kernel (6.14 or newer).
Run something through Wine (for example, winecfg) and, while it's running, execute If you have no How to know if NTSYNC works
lsof /dev/ntsync command. If you see your Wine process IDs there, then NTSYNC works and Wine uses it, otherwise it most likely does not work. An example of working NTSYNC:
$ lsof /dev/ntsync
lsof: WARNING: can't stat() tracefs file system /sys/kernel/debug/tracing
