 ### Changed
 
+- Stopped mounting together the directories `/opt/adguardhome/conf` and
+  `/opt/adguardhome/work` in our Docker images ([#2589]).
 - When `dns.bogus_nxdomain` option is used, the server will now transform
   responses if there is at least one bogus address instead of all of them
   ([#2394]).  The new behavior is the same as in `dnsmasq`.
