* NEWS *

debuginfod-client: Default $DEBUGINFOD_URLS is computed from drop-in files
                   /etc/debuginfod/*.urls rather than hardcoded into the
                   /etc/profile.d/debuginfod* scripts.
                   Add $DEBUGINFOD_MAXSIZE and $DEBUGINFOD_MAXTIME settings
                   for skipping large/slow transfers.
                   Add $DEBUGINFOD_RETRY for retrying aborted lookups.

debuginfod: Supply extra HTTP response headers, describing archive/file
            names that satisfy the requested buildid content.
            Support -d :memory: option for in-memory databases.
            Protect against loops in federated server configurations.
            Add -r option to use -I/-X regexes for grooming stale files.
            Protect against wasted CPU from duplicate concurrent requests.
            Limit the duration of groom ops roughly to rescan (-t) times.
            Add --passive mode for serving from read-only database.
            Several other performance improvements & prometheus metrics.

libdw: Support for the NVIDIA Cuda line map extensions.
       DW_LNE_NVIDIA_inlined_call and DW_LNE_NVIDIA_set_function_name
       are defined in dwarf.h. New functions dwarf_linecontext and
       dwarf_linefunctionname

translations: Update Japanese translation.
