New release: v1.20
btf_encoder:
Improve ELF error reporting using elf_errmsg(elf_errno())

Use kernel module ftrace addresses when finding which functions to encode.
libbpf:
Allow use of packaged version.
dwarf_loader:
Support DW_AT_data_bit_offset
DW_FORM_implicit_const in attr_numeric() and attr_offset()
Support DW_TAG_GNU_call_site, standardized rename of DW_TAG_GNU_call_site.
build:
Fix compilation on 32-bit architectures.

New release: 1.19
Split BTF
DWARF workarounds for DW_AT_declaration
Support cross-compiled ELF binaries with different endianness
Support showing typedefs for anonymous types
Speedups using libbpf algorithms
See changes-v1.19 for a complete and more detailed list of changes

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.

Fix FTBFS
Resolves: bug 1863459

Second attempt - Rebuilt for

Rebuilt for https://fedoraproject.org/wiki/Fedora_33_Mass_Rebuild

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

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.
