 #### Performance Improvement
 * Distinct optimization for sorted columns. Use specialized distinct transformation in case input stream is sorted by column(s) in distinct. Optimization can be applied to pre-distinct, final distinct, or both. Initial implementation by @dimarub2000. [#37803](https://github.com/ClickHouse/ClickHouse/pull/37803) ([Igor Nikonov](https://github.com/devcrafter)).
 * Improve performance of `ORDER BY`, `MergeTree` merges, window functions using batch version of `BinaryHeap`. [#38022](https://github.com/ClickHouse/ClickHouse/pull/38022) ([Maksim Kita](https://github.com/kitaisreal)).
-* Fix significant join performance regression which was introduced in https://github.com/ClickHouse/ClickHouse/pull/35616 . It's interesting that common join queries such as ssb queries have been 10 times slower for almost 3 months while no one complains. [#38052](https://github.com/ClickHouse/ClickHouse/pull/38052) ([Amos Bird](https://github.com/amosbird)).
+* More parallel execution for queries with `FINAL` [#36396](https://github.com/ClickHouse/ClickHouse/pull/36396) ([Nikita Taranov](https://github.com/nickitat)).

[#38052](https://github.com/ClickHouse/ClickHouse/pull/38052) ([Amos Bird](https://github.com/amosbird)).
 * Migrate from the Intel hyperscan library to vectorscan, this speeds up many string matching on non-x86 platforms. [#38171](https://github.com/ClickHouse/ClickHouse/pull/38171) ([Robert Schulze](https://github.com/rschu1ze)).
 * Increased parallelism of query plan steps executed after aggregation. [#38295](https://github.com/ClickHouse/ClickHouse/pull/38295) ([Nikita Taranov](https://github.com/nickitat)).
 * Improve performance of insertion to columns of type `JSON`. [#38320](https://github.com/ClickHouse/ClickHouse/pull/38320) ([Anton Popov](https://github.com/CurtizJ)).
@ -59,7 +61,6 @@
 * `ORDER BY (a, b)` will use all the same benefits as `ORDER BY a, b`. [#38873](https://github.com/ClickHouse/ClickHouse/pull/38873) ([Igor Nikonov](https://github.com/devcrafter)).
 * Align branches within a 32B boundary to make benchmark more stable. [#38988](https://github.com/ClickHouse/ClickHouse/pull/38988) ([Guo Wangyang](https://github.com/guowangy)). It improves performance 1..2% on average for Intel.
 * Executable UDF, executable dictionaries, and Executable tables will avoid wasting one second during wait for subprocess termination. [#38929](https://github.com/ClickHouse/ClickHouse/pull/38929) ([Constantine Peresypkin](https://github.com/pkit)).
-* TODO remove? Pushdown filter to the right side of sorting join. [#39123](https://github.com/ClickHouse/ClickHouse/pull/39123) ([Vladimir C](https://github.com/vdimir)).
 * Optimize accesses to `system.stack_trace` table if not all columns are selected. [#39177](https://github.com/ClickHouse/ClickHouse/pull/39177) ([Azat Khuzhin](https://github.com/azat)).
 * Improve isNullable/isConstant/isNull/isNotNull performance for LowCardinality argument. [#39192](https://github.com/ClickHouse/ClickHouse/pull/39192) ([Kruglov Pavel](https://github.com/Avogar)).
 * Optimized processing of ORDER BY in window functions. [#34632](https://github.com/ClickHouse/ClickHouse/pull/34632) ([Vladimir Chebotarev](https://github.com/excitoon)).

+
+### ClickHouse release v22.7.1.2484-stable (f4f05ec786a) FIXME as compared to v22.6.1.1985-stable (7000c4e0033)
+
+#### Backward Incompatible Change
+* Enable setting `enable_positional_arguments` by default. It allows queries like `SELECT ... ORDER BY 1, 2` where 1, 2 are the references to the select clause. If you need to return the old behavior, disable this setting. [#38204](https://github.com/ClickHouse/ClickHouse/pull/38204) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* `Ordinary` database engine and old storage definition syntax for `*MergeTree` tables are deprecated. By default it's not possible to create new ones. If `system` database has `Ordinary` engine it will be automatically converted to `Atomic` on server startup. There are settings to keep old behavior (`allow_deprecated_database_ordinary` and `allow_deprecated_syntax_for_merge_tree`), but these settings may be removed in future releases. [#38335](https://github.com/ClickHouse/ClickHouse/pull/38335) ([Alexander Tokmakov](https://github.com/tavplubix)).
+* * Force rewriting comma join to inner by default (set default value `cross_to_inner_join_rewrite = 2`). To have old behavior set `cross_to_inner_join_rewrite = 1`. [#39326](https://github.com/ClickHouse/ClickHouse/pull/39326) ([Vladimir C](https://github.com/vdimir)).
+* Disable format_csv_allow_single_quotes by default. [#37096](https://github.com/ClickHouse/ClickHouse/issues/37096). [#39423](https://github.com/ClickHouse/ClickHouse/pull/39423) ([Kruglov Pavel](https://github.com/Avogar)).
+
+#### New Feature

 These codecs are designed to make compression more effective by using specific features of data. Some of these codecs do not compress data themself. Instead, they prepare the data for a common purpose codec, which compresses it better than without this preparation.

-## How ClickHouse documentation is generated? {#how-clickhouse-documentation-is-generated}
+## Generating ClickHouse documentation {#how-clickhouse-documentation-is-generated}

-ClickHouse documentation is built using [build.py](build.py) script that uses [mkdocs](https://www.mkdocs.org) library and it’s dependencies to separately build all version of documentations (all languages in either single and multi page mode) as static HTMLs for each single page version. The results are then put in the correct directory structure. It is recommended to use Python 3.7 to run this script.
+ClickHouse documentation is built using [Docusaurus](https://docusaurus.io). 

-[release.sh](release.sh) also pulls static files needed for [official ClickHouse website](https://clickhouse.com) from [../../website](../../website) folder then pushes to specified GitHub repo to be served via [GitHub Pages](https://pages.github.com).
+## Check the look of your documentation changes {#how-to-check-if-the-documentation-will-look-fine}

-## How to check if the documentation will look fine? {#how-to-check-if-the-documentation-will-look-fine}
+There are a few options that are all useful depending on how large or complex your edits are.

-There are few options that are all useful depending on how large or complex your edits are.
+### Use the GitHub web interface to edit

-### Use GitHub web interface to edit
+Every page in the docs has an **Edit this page** link that opens the page in the GitHub editor.  GitHub has Markdown support with a preview feature. The details of GitHub Markdown and the documentation Markdown are a bit different but generally this is close enough, and the person merging your PR will build the docs and check them.

-GitHub has Markdown support with preview feature, but the details of GitHub Markdown dialect are a bit different in ClickHouse documentation.
+### Install a Markdown editor or plugin for your IDE {#install-markdown-editor-or-plugin-for-your-ide}

-### Install Markdown editor or plugin for your IDE {#install-markdown-editor-or-plugin-for-your-ide}
+Usually, these plugins provide a preview of how the markdown will render, and they catch basic errors like unclosed tags very early.

-Usually those also have some way to preview how Markdown will look like, which allows to catch basic errors like unclosed tags very early.

-### Use build.py {#use-build-py}
+## Build the docs locally {#use-build-py}

-It’ll take some effort to go through, but the result will be very close to production documentation.
+You can build the docs locally.  It takes a few minutes to set up, but once you have done it the first time, the process is very simple.

-For the first time you’ll need to:
+### Clone the repos

-#### 1. Set up virtualenv
+The documentation is in two repos, clone both of them:
+- [ClickHouse/ClickHouse](https://github.com/ClickHouse/ClickHouse)
+- [ClickHouse/ClickHouse-docs](https://github.com/ClickHouse/clickhouse-docs)

-``` bash
-$ cd ClickHouse/docs/tools
-$ mkdir venv
-$ virtualenv -p $(which python3) venv
-$ source venv/bin/activate
-$ pip3 install -r requirements.txt
+### Install Node.js
+
+The documentation is built with Docusaurus, which requires Node.js.  We recommend version 16. Install [Node.js](https://nodejs.org/en/download/).
+
+### Copy files into place
+
+Docusaurus expects all of the markdown files to be located in the directory tree `clickhouse-docs/docs/`.  This is not the way our repos are set up, so some copying of files is needed to build the docs:
+
+```bash
+# from the parent directory of both the ClickHouse/ClickHouse and ClickHouse-clickhouse-docs repos:
+cp -r ClickHouse/docs/en/development     clickhouse-docs/docs/en/
+cp -r ClickHouse/docs/en/engines         clickhouse-docs/docs/en/
+cp -r ClickHouse/docs/en/getting-started clickhouse-docs/docs/en/
+cp -r ClickHouse/docs/en/interfaces      clickhouse-docs/docs/en/
+cp -r ClickHouse/docs/en/operations      clickhouse-docs/docs/en/
+cp -r ClickHouse/docs/en/sql-reference   clickhouse-docs/docs/en/
+
+cp -r ClickHouse/docs/ru/*               clickhouse-docs/docs/ru/
+cp -r ClickHouse/docs/zh                 clickhouse-docs/docs/
 ```

-#### 2. Run build.py
+#### Note: Symlinks will not work.
+### Setup Docusaurus

-When all prerequisites are installed, running `build.py` without args (there are some, check `build.py --help`) will generate `ClickHouse/docs/build` folder with complete static html website.
+There are two commands that you may need to use with Docusaurus:
+- `yarn install`
+- `yarn start`

-The easiest way to see the result is to use `--livereload=8888` argument of build.py. Alternatively, you can manually launch a HTTP server to serve the docs, for example by running `cd ClickHouse/docs/build && python3 -m http.server 8888`. Then go to http://localhost:8888 in browser. Feel free to use any other port instead of 8888.
+#### Install Docusaurus and its dependencies:
+
+```bash
+cd clickhouse-docs
+yarn install
+```
+
+#### Start a development Docusaurus environment
+
+This command will start Docusaurus in development mode, which means that as you edit source (for example, `.md` files) files the changes will be rendered into HTML files and served by the Docusaurus development server.
+
+```bash
+yarn start
+```
+
+### Make your changes to the markdown files
+
+Edit your files.  Remember that if you are editing files in the `ClickHouse/ClickHouse` repo then you should edit them
+in that repo and then copy the edited file into the `ClickHouse/clickhouse-docs/` directory structure so that they are updated in your develoment environment.
+
+`yarn start` probably opened a browser for you when you ran it; if not, open a browser to `http://localhost:3000/docs/en/intro` and navigate to the documentation that you are changing.  If you have already made the changes, you can verify them here; if not, make them, and you will see the page update as you save the changes.  

 ## How to change code highlighting? {#how-to-change-code-hl}

-ClickHouse does not use mkdocs `highlightjs` feature. It uses modified pygments styles instead.
-If you want to change code highlighting, edit the `website/css/highlight.css` file.
-Currently, an [eighties](https://github.com/idleberg/base16-pygments/blob/master/css/base16-eighties.dark.css) theme
-is used.
+Code highlighting is based on the language chosen for your code blocks.  Specify the language when you start the code block:

+<pre lang="no-highlight"><code>```sql
+SELECT firstname from imdb.actors;
+```
+</code></pre>
+
+```sql
+SELECT firstname from imdb.actors;
+```
+
+If you need a language supported then open an issue in [ClickHouse-docs](https://github.com/ClickHouse/clickhouse-docs/issues).
