  - New release: 1.16
  - BTF encoder: Preserve and encode exported functions as BTF_KIND_FUNC.
  - BTF loader: Add support for BTF_KIND_FUNC
  - Pretty printer: Account inline type __aligned__ member types for spacing
  - Pretty printer: Fix alignment of class members that are structs/enums/unions
  - Pretty printer: Avoid infinite loop trying to determine type with static data member of its own type.
  - RPM spec file:  Add dwarves dependency on libdwarves1.
  - pfunct: type->type == 0 is void, fix --compile for that
  - pdwtags: Print DW_TAG_subroutine_type as well
  - core: Fix ptr_table__add_with_id() handling of pt->nr_entries
  - pglobal: Allow passing the format path specifier, to use with BTF
  - Tree wide: Fixup issues pointed out by various coverity reports.


author: Arnaldo Carvalho de Melo <acme@redhat.com> - 1.17-1
changelog:
  - New release: 1.17
  - Support raw BTF as available in /sys/kernel/btf/vmlinux.
  - When the sole argument passed isn't a file, take it as a class name:
  - Do not require a class name to operate without a file name.
  - Make --find_pointers_to consider unions:
  - Make --contains and --find_pointers_to honour --unions
  - Add support for finding pointers to void:
  - Make --contains and --find_pointers_to to work with base types:
  - Make --contains look for more than just unions, structs:
  - Consider unions when looking for classes containing some class:
  - Introduce --unions to consider just unions:
  - Fix -m/--nr_methods - Number of functions operating on a type pointer

changelog:
  - New release: 1.18
  - Use debugging info to pretty print raw data
  - Store percpu variables in vmlinux BTF.
  - Fixes to address segfaults on the gdb testsuite binaries
  - Bail out on partial units for now, avoiding segfaults and providing warning to user.
