# 2022 Changelog
### ClickHouse release v21.12.1.9017-prestable FIXME as compared to v21.11.1.8636-prestable
#### Backward Incompatible Change
* Add custom null representation support for TSV/CSV input formats. Fix deserialing Nullable(String) in TSV/CSV/JSONCompactStringsEachRow/JSONStringsEachRow input formats. Rename `output_format_csv_null_representation` and `output_format_tsv_null_representation` to `format_csv_null_representation` and `format_tsv_null_representation` accordingly. [#30497](https://github.com/ClickHouse/ClickHouse/pull/30497) ([Kruglov Pavel](https://github.com/Avogar)).
* Return unquoted string in JSON_VALUE. Closes [#27965](https://github.com/ClickHouse/ClickHouse/issues/27965). [#31008](https://github.com/ClickHouse/ClickHouse/pull/31008) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Do not allow direct select for Kafka/RabbitMQ/FileLog. Can be enables by setting `stream_like_engine_allow_direct_select`. Direct select will be not allowed even if enabled by setting in case there is attached materialized view. For Kafka and RabbitMQ direct select if allowed, will not commit massages by default. To enable commits with direct select user must use storage level setting `kafka{rabbitmq}_commit_on_select=1` (default `0`). cc @filimonov. [#31053](https://github.com/ClickHouse/ClickHouse/pull/31053) ([Kseniia Sumarokova](https://github.com/kssenii)).
* A "leader election" mechanism is removed from `ReplicatedMergeTree`, because multiple leaders are supported since 20.6. If you are upgrading from older version and some replica with old version is a leader, then server will fail to start after upgrade. Stop replicas with old version to make new version start. After that it will not be possible to downgrade to version older than 20.6. [#32140](https://github.com/ClickHouse/ClickHouse/pull/32140) ([Alexander Tokmakov](https://github.com/tavplubix)).

* - Added CONSTRAINT ... ASSUME ... (without checking during INSERT) - Added query transformation to CNF (https://github.com/ClickHouse/ClickHouse/issues/11749) for more convenient optimization - Added simple query rewriting using constraints (only simple matching now, will be improved to support <,=,>... later) - Added ability to replace heavy columns with light - Added ability to use the index in queries. [#18787](https://github.com/ClickHouse/ClickHouse/pull/18787) ([Nikita Vasilev](https://github.com/nikvas0)).

Also more use-cases were covered. [#29799](https://github.com/ClickHouse/ClickHouse/pull/29799) ([Vladimir Chebotarev](https://github.com/excitoon)).

* Support `IF EXISTS` modifier for `RENAME DATABASE`/`TABLE`/`DICTIONARY` query, If this directive is used, one will not get an error if the DATABASE/TABLE/DICTIONARY to be renamed doesn't exist. [#31081](https://github.com/ClickHouse/ClickHouse/pull/31081) ([victorgao](https://github.com/kafka1991)).

[#31180](https://github.com/ClickHouse/ClickHouse/pull/31180) ([Alexander Tokmakov](https://github.com/tavplubix)).
