 * Add new setting `disable_url_encoding` that allows to disable decoding/encoding path in uri in URL engine. [#52337](https://github.com/ClickHouse/ClickHouse/pull/52337) ([Kruglov Pavel](https://github.com/Avogar)).
 
 #### Performance Improvement
-* Writing parquet files is 10x faster, it's multi-threaded now. Almost the same speed as reading. [#49367](https://github.com/ClickHouse/ClickHouse/pull/49367) ([Michael Kolupaev](https://github.com/al13n321)).
 * Enable automatic selection of the sparse serialization format by default. It improves performance. The format is supported since version 22.1. After this change, downgrading to versions older than 22.1 might not be possible. You can turn off the usage of the sparse serialization format by providing the `ratio_of_defaults_for_sparse_serialization = 1` setting for your MergeTree tables. [#49631](https://github.com/ClickHouse/ClickHouse/pull/49631) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
 * Enable `move_all_conditions_to_prewhere` and `enable_multiple_prewhere_read_steps` settings by default. [#46365](https://github.com/ClickHouse/ClickHouse/pull/46365) ([Alexander Gololobov](https://github.com/davenger)).
 * Improves performance of some queries by tuning allocator. [#46416](https://github.com/ClickHouse/ClickHouse/pull/46416) ([Azat Khuzhin](https://github.com/azat)).

 * Now interserver port will be closed only after tables are shut down. [#52498](https://github.com/ClickHouse/ClickHouse/pull/52498) ([alesapin](https://github.com/alesapin)).
 
 #### Experimental Feature
+* Writing parquet files is 10x faster, it's multi-threaded now. Almost the same speed as reading. [#49367](https://github.com/ClickHouse/ClickHouse/pull/49367) ([Michael Kolupaev](https://github.com/al13n321)). This is controlled by the setting `output_format_parquet_use_custom_encoder` which is disabled by default, because the feature is non-ideal.
 * Added support for [PRQL](https://prql-lang.org/) as a query language. [#50686](https://github.com/ClickHouse/ClickHouse/pull/50686) ([János Benjamin Antal](https://github.com/antaljanosbenjamin)).
 * Allow to add disk name for custom disks. Previously custom disks would use an internal generated disk name. Now it will be possible with `disk = disk_<name>(...)` (e.g. disk will have name `name`) . [#51552](https://github.com/ClickHouse/ClickHouse/pull/51552) ([Kseniia Sumarokova](https://github.com/kssenii)). This syntax can be changed in this release.
 * (experimental MaterializedMySQL) Fixed crash when `mysqlxx::Pool::Entry` is used after it was disconnected. [#52063](https://github.com/ClickHouse/ClickHouse/pull/52063) ([Val Doroshchuk](https://github.com/valbok)).

+* Backported in [#52826](https://github.com/ClickHouse/ClickHouse/issues/52826): Fix incorrect projection analysis which invalidates primary keys. This issue only exists when `query_plan_optimize_primary_key = 1, query_plan_optimize_projection = 1` . This fixes [#48823](https://github.com/ClickHouse/ClickHouse/issues/48823) . This fixes [#51173](https://github.com/ClickHouse/ClickHouse/issues/51173) . [#52308](https://github.com/ClickHouse/ClickHouse/pull/52308) ([Amos Bird](https://github.com/amosbird)).
+
+#### Build/Testing/Packaging Improvement
+* Backported in [#53019](https://github.com/ClickHouse/ClickHouse/issues/53019): Packing inline cache into docker images sometimes causes strange special effects. Since we don't use it at all, it's good to go. [#53008](https://github.com/ClickHouse/ClickHouse/pull/53008) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+* Backported in [#53288](https://github.com/ClickHouse/ClickHouse/issues/53288): The compiler's profile data (`-ftime-trace`) is uploaded to ClickHouse Cloud., the second attempt after [#53100](https://github.com/ClickHouse/ClickHouse/issues/53100). [#53213](https://github.com/ClickHouse/ClickHouse/pull/53213) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Backported in [#53461](https://github.com/ClickHouse/ClickHouse/issues/53461): Preserve environment parameters in `clickhouse start` command. Fixes [#51962](https://github.com/ClickHouse/ClickHouse/issues/51962). [#53418](https://github.com/ClickHouse/ClickHouse/pull/53418) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+
+#### Bug Fix (user-visible misbehavior in an official stable release)
+
+* Fix optimization to move functions before sorting. [#51481](https://github.com/ClickHouse/ClickHouse/pull/51481) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).

+* Fix ORDER BY tuple of WINDOW functions [#52145](https://github.com/ClickHouse/ClickHouse/pull/52145) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Disable expression templates for time intervals [#52335](https://github.com/ClickHouse/ClickHouse/pull/52335) ([Alexander Tokmakov](https://github.com/tavplubix)).
+* Fix `countSubstrings()` hang with empty needle and a column haystack [#52409](https://github.com/ClickHouse/ClickHouse/pull/52409) ([Sergei Trifonov](https://github.com/serxa)).
+* Fixed inserting into Buffer engine [#52440](https://github.com/ClickHouse/ClickHouse/pull/52440) ([Vasily Nemkov](https://github.com/Enmk)).
+* The implementation of AnyHash was non-conformant. [#52448](https://github.com/ClickHouse/ClickHouse/pull/52448) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* init and destroy ares channel on demand.. [#52634](https://github.com/ClickHouse/ClickHouse/pull/52634) ([Arthur Passos](https://github.com/arthurpassos)).

+## USearch {#usearch}
+
+This type of ANN index is based on the [the USearch library](https://github.com/unum-cloud/usearch), which implements the [HNSW
+algorithm](https://arxiv.org/abs/1603.09320), i.e., builds a hierarchical graph where each point represents a vector and the edges represent
+similarity. Such hierarchical structures can be very efficient on large collections. They may often fetch 0.05% or less data from the
+overall dataset, while still providing 99% recall. This is especially useful when working with high-dimensional vectors,
+that are expensive to load and compare. The library also has several hardware-specific SIMD optimizations to accelerate further
+distance computations on modern Arm (NEON and SVE) and x86 (AVX2 and AVX-512) CPUs and OS-specific optimizations to allow efficient
+navigation around immutable persistent files, without loading them into RAM.

+
+USearch currently supports two distance functions:
+- `L2Distance`, also called Euclidean distance, is the length of a line segment between two points in Euclidean space
+  ([Wikipedia](https://en.wikipedia.org/wiki/Euclidean_distance)).
+- `cosineDistance`, also called cosine similarity, is the cosine of the angle between two (non-zero) vectors
+  ([Wikipedia](https://en.wikipedia.org/wiki/Cosine_similarity)).
+
+For normalized data, `L2Distance` is usually a better choice, otherwise `cosineDistance` is recommended to compensate for scale. If no
+distance function was specified during index creation, `L2Distance` is used as default.
