 * Allow using extended integer types (`Int128`, `Int256`, `UInt256`) in `avg` and `avgWeighted` functions. Also allow using different types (integer, decimal, floating point) for value and for weight in `avgWeighted` function. This is a backward-incompatible change: now the `avg` and `avgWeighted` functions always return `Float64` (as documented). Before this change the return type for `Decimal` arguments was also `Decimal`. [#15419](https://github.com/ClickHouse/ClickHouse/pull/15419) ([Mike](https://github.com/myrrc)).
 * Expression `toUUID(N)` no longer works. Replace with `toUUID('00000000-0000-0000-0000-000000000000')`. This change is motivated by non-obvious results of `toUUID(N)` where N is non zero.
 * SSL Certificates with incorrect "key usage" are rejected. In previous versions they are used to work. See [#19262](https://github.com/ClickHouse/ClickHouse/issues/19262).
+* `incl` references to substitutions file (`/etc/metrika.xml`) were removed from the default config (`<remote_servers>`, `<zookeeper>`, `<macros>`, `<compression>`, `<networks>`). If you were using substitutions file and were relying on those implicit references, you should put them back manually and explicitly by adding corresponding sections with `incl="..."` attributes before the update. See [#18740](https://github.com/ClickHouse/ClickHouse/pull/18740)  ([alexey-milovidov](https://github.com/alexey-milovidov)).
