* NEWS *

debuginfod: Add CORS (webapp access) support to webapi and --cors option.

    Add --listen-address option for binding the HTTP listen socket
    to a specific IPv4 or IPv6 address.

    debuginfod client now caches x-debuginfod-* HTTP headers
    alongside downloaded files.

libdw: Add dwarf_language and dwarf_language_lower_bound functions.

    Improved support for DWARF6 language metadata as well as DWARF
    language constants for Nim, Dylan, Algol68, V and Mojo.

    dwarf_srclang is now forward-compatible with DWARF6 language
    constants.

libdwfl_stacktrace: Experimental new library interface for unwinding
    stack samples into call chains, and tracking and caching Elf data
    for multiple processes, building on libdwfl.  Initially supports
    perf_events stack sample data.

libelf: elf_scnshndx has been rewritten to be more robust, particularly
    for ELF files with more than 64K sections.

readelf: Improved handling of corrupt ELF data.

    --section-headers output now includes a "Key to Flags" explaining
    section flag meanings.
