Version 5.6 of the Systemtap tracing tool has been released.

BPF LSM hooks and XDP packet-processing probes for the –bpf
runtime, BTF-based kernel.tracepoint probes, statement execution
tracing, a new @enumname() operator, richer runtime error context,
dyninst hardware watchpoints, modern systemd service templates, and
broad Linux 7.2 runtime/tapset compatibility work. Multithreaded
speedups throughout.
