38 | 38 | * Gives the possibility to truncate specific tables from a database, filtered with the `LIKE` keyword. [#78597](https://github.com/ClickHouse/ClickHouse/pull/78597) ([Yarik Briukhovetskyi](https://github.com/yariks5s)). |
39 | 39 | * Support `_part_starting_offset` virtual column in `MergeTree`-family tables. This column represents the cumulative row count of all preceding parts, calculated at query time based on the current part list. The cumulative values are retained throughout query execution and remain effective even after part pruning. Related internal logic has been refactored to support this behavior. [#79417](https://github.com/ClickHouse/ClickHouse/pull/79417) ([Amos Bird](https://github.com/amosbird)). |
40 | 40 | * Add functions `divideOrNull`,`moduloOrNull`, `intDivOrNull`,`positiveModuloOrNull` to return NULL when right argument is zero. [#78276](https://github.com/ClickHouse/ClickHouse/pull/78276) ([kevinyhzou](https://github.com/KevinyhZou)). |
| 41 | +* Clickhouse vector search now supports both pre-filtering and post-filtering and provides related settings for finer control. (issue [#78161](https://github.com/ClickHouse/ClickHouse/issues/78161)). [#79854](https://github.com/ClickHouse/ClickHouse/pull/79854) ([Shankar Iyer](https://github.com/shankar-iyer)). |
41 | 42 | * Add [`icebergHash`](https://iceberg.apache.org/spec/#appendix-b-32-bit-hash-requirements) and [`icebergBucket`](https://iceberg.apache.org/spec/#bucket-transform-details) functions. Support data files pruning in `Iceberg` tables partitioned with [`bucket transfom`](https://iceberg.apache.org/spec/#partitioning). [#79262](https://github.com/ClickHouse/ClickHouse/pull/79262) ([Daniil Ivanik](https://github.com/divanik)). |

43 | 44 | #### Experimental Feature |
|
112 | 113 | * Enable sending crash reports by default. This can be turned off in the server's configuration file. [#79838](https://github.com/ClickHouse/ClickHouse/pull/79838) ([Alexey Milovidov](https://github.com/alexey-milovidov)). |
113 | 114 | * System table `system.functions` now shows in which ClickHouse version functions were first introduced. [#79839](https://github.com/ClickHouse/ClickHouse/pull/79839) ([Robert Schulze](https://github.com/rschu1ze)). |
114 | 115 | * Added `access_control_improvements.enable_user_name_access_type` setting. This setting allows enabling/disabling of precise grants for users/roles, introduced in https://github.com/ClickHouse/ClickHouse/pull/72246. You may want to turn this setting off in case you have a cluster with the replicas older than 25.1. [#79842](https://github.com/ClickHouse/ClickHouse/pull/79842) ([pufit](https://github.com/pufit)). |
115 | | -* Clickhouse vector search now supports both pre-filtering and post-filtering and provides related settings for finer control. (issue [#78161](https://github.com/ClickHouse/ClickHouse/issues/78161)). [#79854](https://github.com/ClickHouse/ClickHouse/pull/79854) ([Shankar Iyer](https://github.com/shankar-iyer)). |
116 | 116 | * Proper implementation of `ASTSelectWithUnionQuery::clone()` method now takes into account `is_normalized` field as well. This might help with [#77569](https://github.com/ClickHouse/ClickHouse/issues/77569). [#79909](https://github.com/ClickHouse/ClickHouse/pull/79909) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)). |
117 | 117 | * Fix the inconsistent formatting of certain queries with the EXCEPT operator. If the left-hand side of the EXCEPT operator ends with `*`, the formatted query loses parentheses and is then parsed as a `*` with the `EXCEPT` modifier. These queries are found by the fuzzer and are unlikely to be found in practice. This closes [#79950](https://github.com/ClickHouse/ClickHouse/issues/79950). [#79952](https://github.com/ClickHouse/ClickHouse/pull/79952) ([Alexey Milovidov](https://github.com/alexey-milovidov)). |
118 | 118 | * Small improvement in `JSON` type parsing by using cache of variants deserialization order. [#79984](https://github.com/ClickHouse/ClickHouse/pull/79984) ([Pavel Kruglov](https://github.com/Avogar)). |
