+
+    Release 2.7.0
+
+    This release adds DNS-over-HTTPS support!
+
+    DNS-over-HTTPS can be used by specifying transport mode `doh` and you
+    should also look at the dnsperf(1) man-page (or `-H`) for the extended
+    options `doh-uri` and `doh-method`, which controls aspects of DoH/HTTP/2
+    that you might want to set.
+
+    Other fixes:
+    - Add check when constructing DNS packet so that total length of labels
+      does not exceed 255 bytes
+    - Fix connection/reconnection state handling for DoT transport
+    - Fix event handling by initializing them directly when opening the
+      sockets, otherwise events could have been missed which would give
+      incorrect statistics
