- Update to release 0.8.0
  * New features and APIs:
    - support auto-resolution of binaries and shared libraries from PATH, if necessary;
    - support attaching by function names (only by IP was supported before);
    - support attaching to USDTs (SEC("usdt/...") and
      bpf_program__attach_usdt()) with initially supported architectures:
      x86-64 (amd64); x86 (i386); s390x; ARM64 (aarch64); RISC V (riscv);
    - improved BPF verifier log reporting for CO-RE relocation failures (no
      more obscure "invalid func unknown#195896080" errors);
    - auto-adjust BPF ringbuf size according to host kernel's page size requirements;
    - high-level BPF map APIs: bpf_map__lookup_elem(), bpf_map__update_elem(),
      etc that validate key/value buffer sizes;
    - bpf_link_create() can create all bpf_link-based (including raw_tp,
      fentry/fexit, etc), falling back to bpf_raw_tracepoint_open() on old
      kernels transparently;
    - support opting out from auto-loading BPF programs declaratively with
      SEC("?...");
    - support opting out from auto-creation of declarative BPF maps with
      bpf_map__set_autocreate();
    - support multi-kprobes (SEC("kprobe.multi/...") and
      bpf_program__attach_kprobe_multi_opts());
    - support target-less SEC() programs (e.g., SEC("kprobe"), SEC("tp"), etc);
    - support BPF sub-skeletons for "incomplete" BPF object files (requires
      matching bpftool to generate .subskel.h);
    - BPF cookie support for fentry/fexit/fmod_ret BPF programs
      (bpf_program__attach_trace_opts());
    - support for custom SEC() handlers (libbpf_register_prog_handler()).
  * BPF-side API
    - BPF-side USDT APIs. See new usdt.bpf.h header:
      * BPF_USDT() program wrapper macro; bpf_usdt_arg(), bpf_usdt_arg_cnt(),
      * bpf_usdt_cookie() helpers;
    - new bpf_core_field_offset() CO-RE helper and support
      bpf_core_field_size(type, field) forms;
    - barrier() and barrier_var() macros for improving BPF code generation;
    - __kptr and __kptr_ref tags added;
    - ARC architecture support in bpf_tracing.h header;
    - new BPF helpers:
      * bpf_skb_set_tstamp();
      * bpf_ima_file_hash();
      * bpf_kptr_xchg();
      * bpf_map_lookup_percpu_elem().
  * Bug fixes
    - netlink bug fixes;
    - libbpf.pc fixes to support patch releases properly;
    - BPF_MAP_TYPE_PERF_EVENT_ARRAY map auto-pinning fix;
    - minor CO-RE fixes and improvements for some corner cases;
    - various other small fixes and improvements.

- Update to 0.5.0:
  + New features and user-space APIs:
    - libbpf_set_strict_mode() allowing to opt-in into backwards incompatible libbpf-1.0 changes. See "Libbpf: the road to 1.0" and "Libbpf 1.0 migration guide" for more details.

    - BPF_PROG_TYPE_SYSCALL support;
    - BPF perf link support for kprobe, uprobe, tracepoint, and perf_event BPF programs;

    - 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_get_func_ip() helper;
    - bpf_sys_bpf() helper;
    - bpf_task_pt_regs() helper;
    - bpf_btf_find_by_name_kind() helper;
