+
+    Release 2.15.0
+
+    This release fixes DNS parsing w.r.t. EDNS, implements better loop
+    detection during name decompression and adds a lot of EDNS indexers
+    and filters.
+
+    Previously the DNS parser expected the additional records to come
+    straight after the question section. Meaning that if the DNS packet
+    had any answer or authority records, they would be parsed as additional
+    records for the OPT record and EDNS information.
+
+    Following new indexers has been added:
+    - edns_cookie
+    - edns_cookie_len
+    - edns_cookie_client
+    - edns_cookie_server
+    - edns_ecs
+    - edns_ecs_family
+    - edns_ecs_source_prefix
+    - edns_ecs_scope_prefix
+    - edns_ecs_address
+    - edns_ecs_subnet
+    - edns_ede
+    - edns_ede_code
+    - edns_ede_textlen
+    - edns_ede_text
+    - edns_nsid
+    - edns_nsid_len
+    - edns_nsid_data
+    - edns_nsid_text
+
+    Following new filters has been added:
+    - edns0-only
+    - edns0-cookie-only
+    - edns0-nsid-only
+    - edns0-ede-only
+    - edns0-ecs-only
+
+    See man-page dsc.conf(5) for more information.
+
+    Other fixes/additions:
+    - Only parse entire DNS message if EDNS indexers are used
+    - `dns_protocol`: Implement proper loop detection during decompression
+    - `xmalloc`: Check return of `amalloc()` before using `memset()`/`memcpy()` because it's undefined behavior on null pointers
+
+    8259f30 EDNS filters
+    41f3b9a strtohex, nsid text
+    a666c04 EDNS(0) Client Subnet
