    - BPF_PROG_TYPE_SYSCALL support;
    - BPF perf link support for kprobe, uprobe, tracepoint, and perf_event BPF programs;
    - BPF cookie support for kprobe, uprobe, tracepoint, and perf_event BPF programs through bpf_program__attach_[ku]probe_opts() APIs;
    - allow to specify ref_ctr_off for USDT semaphores through bpf_program__attach_uprobe_opts() API;
    - btf_custom_path support in bpf_object_open_opts, allowing to specify custom BTF for CO-RE relocations;
    - sk_reuseport/migrate program type support;
    - btf_dump__dump_type_data() API, allowing to dump binary data according to BTF type description;
    - btf__load_into_kernel() and btf__load_from_kernel_by_id(), and split BTF variants of them;
    - btf__load_vmlinux_btf() and btf__load_module_btf() APIs;
    - bpf_map__initial_value() API to get initial value of mmap-ed BPF maps;
    - bpf_map_lookup_and_delete_elem_flags() API.
  + BPF-side APIs and features:
    - support for weak typed __ksym externs;
    - BPF timer helpers: bpf_timer_init(), bpf_timer_set_callback(), bpf_timer_start(), bpf_timer_cancel();
    - bpf_get_attach_cookie() helper to get BPF cookie from BPF program side;
    - bpf_get_func_ip() helper;
    - bpf_sys_bpf() helper;
    - bpf_task_pt_regs() helper;
    - bpf_btf_find_by_name_kind() helper;
    - usability improvements for bpf_tracing.h when target architecture is missing.
  + Bug fixes and compatibility improvements:
    - improve BPF support detection on old Red Hat kernels with backported BPF patches;
    - improvements for LTO builds with GCC 10+;
    - pass NLM_F_EXCL when creating TC qdisc;
    - better support of BPF map reuse on old kernels;
