* Multiple JOINS with some restrictions: no asterisks, no complex aliases in ON/WHERE/GROUP BY/... [#4462](https://github.com/yandex/ClickHouse/pull/4462)([Artem Zuikov](https://github.com/4ertus2))
### Bug Fixes
* This release also contains all bug fixes from 19.3 and 19.1.
* Fixed bug in data skipping indices: order of granules after INSERT was incorrect. [#4407](https://github.com/yandex/ClickHouse/pull/4407)([Nikita Vasilev](https://github.com/nikvas0))
* Fixed `set` index for `Nullable` and `LowCardinality` columns. Before it, `set` index with `Nullable` or `LowCardinality` column led to error `Data type must be deserialized with multiple streams` while selecting. [#4594](https://github.com/yandex/ClickHouse/pull/4594)([Nikolai Kochetov](https://github.com/KochetovNicolai))
* Correctly set update_time on full `executable` dictionary update. [#4551](https://github.com/yandex/ClickHouse/pull/4551)([Tema Novikov](https://github.com/temoon))
