+* Thu Nov 25 2021 Mark Wielaard <mjw@fedoraproject.org> - 0.186-1
+- Upgrade to upstream 0.186
+  - 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.
+
 * Thu May 27 2021 Mark Wielaard <mjw@fedoraproject.org> - 0.185-2
 - Disable debuginfod client by default for f34.
