Wed Jun 14 2023 Viktor Malik <vmalik@redhat.com> - 1.25-1
- Resolves: rhbz#2190484
- Build with system libbpf
- New release: v1.25
- Support for DW_TAG_unspecified_type more generally.
- Make sure struct member offsets are in ascending order. Rust BTF needs this.
- Support C atomic types (DW_TAG_atomic_type).
- Initial support for DW_TAG_LLVM_annotation, used for BTF type tags, for __rcu, __user, etc
- Exclude functions with the same name (static functions in different CUs), inconsistent prototypes or not following calling convention.
- Allow generation of BTF for optimized functions, those that end with a .isra*, .constprop*.
- Support 'pahole --lang=/--lang_exclude=asm'
- Support --compile from DWARF in addition to from BTF.
- Exclude RUST CUs in 'btfdiff', as those are not yet being BTF encoded.

Wed Oct 06 2021 Jiri Olsa <jolsa@redhat.com> - 1.22-1
- New release: v1.22
- Resolves: rhbz#2010414
- Introduce -j/--jobs option to specify the number of threads to use.
- Multithreaded DWARF loading, requires elfutils >= 0.178.
- Preparatory work for multithreaded BTF encoding, the focus for 1.23.
- Allow encoding BTF to a separate file.
- Show all different types with the same name, not just the first one found.
- Stop assuming that reading from stdin means pretty, add --prettify.
- Improve type resolution for the --header command line option.
- Do not consider the ftrace filter when encoding BTF for kernel functions.
- Lock calls to non-thread safe elfutils' dwarf_decl_file() and dwarf_decl_line().
- Change hash table size to one that performs better with current typical vmlinux files.
- Allow tweaking the hash table size from the command line.
- Add --kabi_prefix to avoid deduplication woes when using _RH_KABI_REPLACE().
- Add --with_flexible_array to show just types with flexible arrays.
- Support btfdiff with a detached BTF file.
- Introduce sorted type output (--sort).
- Disable incomplete CTF encoder.
