 ### Changed
 
+- Instead of adding the build time information, the build scripts now use the
+  standardized environment variable [`SOURCE_DATE_EPOCH`][repr] to add the date
+  of the commit from which the binary was built ([#4221]).  This should simplify
+  reproducible builds for package maintainers and those who compile their own
+  AdGuard Home.
 - The setting `local_domain_name` is now in the `dhcp` block in the
   configuration file to avoid confusion ([#3367]).
 - The `dns.bogus_nxdomain` configuration file parameter now supports CIDR
