 * 23496:Added the new mode of operating [actor system](./concepts/glossary#actor-system), which allows for more efficient use of computing resources – the performance of a 4-core node is increased by 40%, now the performance per core is the same as that of a 10-core node; the performance of a 2-core node is increased by 110%, the performance per core is only 5% less than that of a 10-core node (previously it was 50% less). It is enabled by setting the `use_shared_threads` flag in the [actor-system configuration](./devops/configuration-management/configuration-v1/change_actorsystem_configs).

 * 24666:Fixed an [issue](https://github.com/ydb-platform/ydb/issues/23895) that scalar and block hash shuffles may be incompatible and it causes incorrect results, for example, in hash joins. Now no 2 different kinds of shuffles (SCALAR and BLOCK) should be inputs to the single stage. (#24033) [#24666](https://github.com/ydb-platform/ydb/pull/24666) ([Ivan](https://github.com/abyss7))
