CONTRIBUTING:

elfutils has adopted a policy on the use of Large Language Models
(LLMs).  Contributions containing output generated by LLMs are not
currently being accepted.

debuginfod:

Introduce --home-redirect and --home-html switches allowing for
redirecting to custom URL and/or serving a custom html file, if
document root is requested.  Related: PR33635.

New command line option --max-depth that limits scanner depth.

Metadata queries now support lookup by build-id.

New function debuginfod_default_progressfn added to libdebuginfod.

debuginfod-find:

Fixed bug where DEBUGINFOD_PROGRESS environment variable was ignored if
debuginfod-find was invoked without -v.

elflint:

Recognize .debug_*.dwo sections, .relro_padding sections as well as
SHT_AARCH64_ATTRIBUTES, SHT_LLVM_LTO and SHT_LLVM_ADDRSIG.

Accept R_X86_64_DTPOFF64 in ET_REL files.

Add lints for PT_LOAD, PT_INTERP and PT_PHDR segments.

libdw:

Added language constants for Erlang, Elixir and Gleam.

Fixed bug that caused sections in DWARF package files (.dwp) to be
missed if section .debug_dwp is present.

libdwfl:

Improved handling of Linux kernel object files with sh_addr fields set
to non-zero.

libdwfl_stacktrace:

AArch64 and 32-bit ARM support added.  The libdwfl_stacktrace library
interface is experimental and may be subject to API/ABI changes.

libelf:

New man pages for gelf.h functions.

Fixed gelf_getmove and gelf_update_move assertion failures caused by
incorrect ELFCLASS32/ELFCLASS64 handling.

elf_update now correctly handles binaries with 65280+ sections when
section zero headers aren't loaded.

readelf:

Improved support for DWARF Package Files (.dwp) sections.

Improved output format for .gcc_except_table.

stacktrace:

This experimental tool is scheduled to be removed in the next release
and replaced with the upcoming eu-stackprof tool.
