+### ClickHouse release v21.11, 2021-11-09
+
+#### Backward Incompatible Change
+
+* Change order of json_path and json arguments in SQL/JSON functions (to be consistent with the standard). Closes [#30449](https://github.com/ClickHouse/ClickHouse/issues/30449). [#30474](https://github.com/ClickHouse/ClickHouse/pull/30474) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Remove `MergeTree` table setting `write_final_mark`. It will be always `true`. [#30455](https://github.com/ClickHouse/ClickHouse/pull/30455) ([Kseniia Sumarokova](https://github.com/kssenii)). No actions required, all tables are compatible with the new version.
+* Function `bayesAB` is removed. Please help to return this function back, refreshed. This closes [#26233](https://github.com/ClickHouse/ClickHouse/issues/26233). [#29934](https://github.com/ClickHouse/ClickHouse/pull/29934) ([alexey-milovidov](https://github.com/alexey-milovidov)).
+* This is relevant only if you already started using the experimental `clickhouse-keeper` support. Now ClickHouse Keeper snapshots compressed with `ZSTD` codec by default instead of custom ClickHouse LZ4 block compression. This behavior can be turned off with `compress_snapshots_with_zstd_format` coordination setting (must be equal on all quorum replicas). Backward incompatibility is quite rare and may happen only when new node will send snapshot (happens in case of recovery) to the old node which is unable to read snapshots in ZSTD format. [#29417](https://github.com/ClickHouse/ClickHouse/pull/29417) ([alesapin](https://github.com/alesapin)).
+
+#### New Feature
+
+* New asynchronous INSERT mode allows to accumulate inserted data and store it in a single batch in background. On client it can be enabled by setting `async_insert` for `INSERT` queries with data inlined in query or in separate buffer (e.g. for `INSERT` queries via HTTP protocol). If `wait_for_async_insert` is true (by default) the client will wait until data will be flushed to table. On server-side it controlled by the settings `async_insert_threads`, `async_insert_max_data_size` and `async_insert_busy_timeout_ms`. Implements [#18282](https://github.com/ClickHouse/ClickHouse/issues/18282). [#27537](https://github.com/ClickHouse/ClickHouse/pull/27537) ([Anton Popov](https://github.com/CurtizJ)). [#20557](https://github.com/ClickHouse/ClickHouse/pull/20557) ([Ivan](https://github.com/abyss7)). Notes on performance: with asynchronous inserts you can do up to around 10 000 individual INSERT queries per second, so it is still recommended to insert in batches if you want to achieve performance up to millions inserted rows per second.
+* Add interactive mode for `clickhouse-local`. So, you can just run `clickhouse-local` to get a command line ClickHouse interface without connecting to a server and process data from files and external data sources. Also merge the code of `clickhouse-client` and `clickhouse-local` together. Closes [#7203](https://github.com/ClickHouse/ClickHouse/issues/7203).

[#27933](https://github.com/ClickHouse/ClickHouse/pull/27933) ([Alexey Boykov](https://github.com/mathalex)).
+* Add support for compression and decompression for `INTO OUTFILE` and `FROM INFILE` (with autodetect or with additional optional parameter). [#27135](https://github.com/ClickHouse/ClickHouse/pull/27135) ([Filatenkov Artur](https://github.com/FArthur-cmd)).
+* Add CORS (Cross Origin Resource Sharing) support with HTTP `OPTIONS` request. It means, now Grafana will work with serverless requests without a kludges. Closes [#18693](https://github.com/ClickHouse/ClickHouse/issues/18693). [#29155](https://github.com/ClickHouse/ClickHouse/pull/29155) ([Filatenkov Artur](https://github.com/FArthur-cmd)).

+* `Executable`, `ExecutablePool` added option `send_chunk_header`. If this option is true then chunk rows_count with line break will be sent to client before chunk. [#28833](https://github.com/ClickHouse/ClickHouse/pull/28833) ([Maksim Kita](https://github.com/kitaisreal)).
+* `tokenbf_v1` and `ngram` support Map with key of String of FixedSring type. It enhance data skipping in query with map key filter. ```sql CREATE TABLE map_tokenbf ( row_id UInt32, map Map(String, String), INDEX map_tokenbf map TYPE ngrambf_v1(4,256,2,0) GRANULARITY 1 ) Engine=MergeTree() Order by id ``` With table above, the query `select * from map_tokebf where map['K']='V'` will skip the granule that doesn't contain key `A` . Of course, how many rows will skipped is depended on the `granularity` and `index_granularity` you set. [#28511](https://github.com/ClickHouse/ClickHouse/pull/28511) ([凌涛](https://github.com/lingtaolf)).

+
+#### Performance Improvement
+
+* Background merges can be preempted by each other and they are scheduled with appropriate priorities. Now long running merges won't prevent short merges to proceed. This is needed for a better scheduling and controlling of merges execution. It reduces the chances to get "too many parts" error. [#22381](https://github.com/ClickHouse/ClickHouse/issues/22381). [#25165](https://github.com/ClickHouse/ClickHouse/pull/25165) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)). Added an ability to execute more merges and mutations than the number of threads in background pool. Merges and mutations will be executed step by step according to their sizes (lower is more prioritized). The ratio of the number of tasks to threads to execute is controlled by a setting `background_merges_mutations_concurrency_ratio`, 2 by default. [#29140](https://github.com/ClickHouse/ClickHouse/pull/29140) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
+* Allow to use asynchronous reads for remote filesystems. Lower the number of seeks while reading from remote filesystems. It improves performance tremendously and makes the experimental `web` and `s3` disks to work faster than EBS under certain conditions. [#29205](https://github.com/ClickHouse/ClickHouse/pull/29205) ([Kseniia Sumarokova](https://github.com/kssenii)). In the meantime, the `web` disk type (static dataset hosted on a web server) is graduated from being experimental to be production ready.
+* Queries with `INTO OUTFILE` in `clickhouse-client` will use multiple threads. Fix the issue with flickering progress-bar when using `INTO OUTFILE`. This closes [#30873](https://github.com/ClickHouse/ClickHouse/issues/30873). This closes [#30872](https://github.com/ClickHouse/ClickHouse/issues/30872). [#30886](https://github.com/ClickHouse/ClickHouse/pull/30886) ([alexey-milovidov](https://github.com/alexey-milovidov)).
+* Reduce amount of redundant compressed data read from disk for some types `SELECT` queries (only for `MergeTree` engines family). [#30111](https://github.com/ClickHouse/ClickHouse/pull/30111) ([alesapin](https://github.com/alesapin)).

+* Primary key index and partition filter can work in tuple. [#29281](https://github.com/ClickHouse/ClickHouse/pull/29281) ([凌涛](https://github.com/lingtaolf)).
+* If query has multiple quantile aggregate functions with the same arguments but different level parameter, they will be fused together and executed in one pass if the setting `optimize_syntax_fuse_functions` is enabled. [#26657](https://github.com/ClickHouse/ClickHouse/pull/26657) ([hexiaoting](https://github.com/hexiaoting)).
+* Now min-max aggregation over the first expression of primary key is optimized by projection. This is for [#329](https://github.com/ClickHouse/ClickHouse/issues/329). [#29918](https://github.com/ClickHouse/ClickHouse/pull/29918) ([Amos Bird](https://github.com/amosbird)).

+# How to Build ClickHouse on Linux for RISC-V 64 Architecture {#how-to-build-clickhouse-on-linux-for-risc-v-64-architecture}
+
+As of writing (11.11.2021) building for risc-v considered to be highly experimental. Not all features can be enabled.
+
+This is for the case when you have Linux machine and want to use it to build `clickhouse` binary that will run on another Linux machine with RISC-V 64 CPU architecture. This is intended for continuous integration checks that run on Linux servers.
+
+The cross-build for RISC-V 64 is based on the [Build instructions](../development/build.md), follow them first.

+It is possible to create two `Merge` tables that will endlessly try to read each others' data, but this is not a good idea.

+## Four Latter Word Commands
+
+ClickHouse Keeper also provides 4lw commands which are almost the same with Zookeeper. Each command is composed of four letters such as `mntr`, `stat` etc. There are some more interesting commands: `stat` gives some general information about the server and connected clients, while `srvr` and `cons` give extended details on server and connections respectively.  
+
+The 4lw commands has a white list configuration `four_letter_word_white_list` which has default value "conf,cons,crst,envi,ruok,srst,srvr,stat,wchc,wchs,dirs,mntr,isro".
+
+You can issue the commands to ClickHouse Keeper via telnet or nc, at the client port.
+```
+echo mntr | nc localhost 9181
+```
+
+Bellow is the detailed 4lw commands:
+
+- ruok : Tests if server is running in a non-error state. The server will respond with imok if it is running. Otherwise it will not respond at all. A response of "imok" does not necessarily indicate that the server has joined the quorum, just that the server process is active and bound to the specified client port. Use "stat" for details on state wrt quorum and client connection information.

 ## [experimental] Migration from ZooKeeper
 
 Seamlessly migration from ZooKeeper to ClickHouse Keeper is impossible you have to stop your ZooKeeper cluster, convert data and start ClickHouse Keeper. `clickhouse-keeper-converter` tool allows converting ZooKeeper logs and snapshots to ClickHouse Keeper snapshot. It works only with ZooKeeper > 3.4. Steps for migration:

The probability is for every allocation or deallocations, regardless of the size of the allocation. Note that sampling happens only when the amount of untracked memory exceeds the untracked memory limit (default value is `4` MiB). It can be lowered if [total_memory_profiler_step](#total-memory-profiler-step) is lowered. You can set `total_memory_profiler_step` equal to `1` for extra fine-grained sampling.

The setting value is the number of mapped regions (usually equal to the number of mapped files). The amount of data in mapped files can be monitored in [system.metrics](../../operations/system-tables/metrics.md), [system.metric_log](../../operations/system-tables/metric_log.md) system tables by the `MMappedFiles` and `MMappedFileBytes` metrics, in [system.asynchronous_metrics](../../operations/system-tables/asynchronous_metrics.md), [system.asynchronous_metrics_log](../../operations/system-tables/asynchronous_metric_log.md) by the `MMapCacheCells` metric, and also in [system.events](../../operations/system-tables/events.md), [system.processes](../../operations/system-tables/processes.md), [system.query_log](../../operations/system-tables/query_log.md), [system.query_thread_log](../../operations/system-tables/query_thread_log.md), [system.query_views_log](../../operations/system-tables/query_views_log.md) by the `CreatedReadBufferMMap`, `CreatedReadBufferMMapFailed`, `MMappedFileCacheHits`, `MMappedFileCacheMisses` events. Note that the amount of data in mapped files does not consume memory directly and is not accounted in query or server memory usage — because this memory can be discarded similar to OS page cache. The cache is dropped (the files are closed) automatically on the removal of old parts in tables of the [MergeTree](../../engines/table-engines/mergetree-family/mergetree.md) family, also it can be dropped manually by the `SYSTEM DROP MMAP CACHE` query.

+## exponentialMovingAverage {#exponential-moving-average}
+
+Сalculates the exponential moving average of values for the determined time. 
+
+**Syntax**
+
+```sql
+exponentialMovingAverage(x)(value, timestamp)
+```
+
+Each `value` corresponds to the determinate `timestamp`. The half-life `x` is the time lag at which the exponential weights decay by one-half. The function returns a weighted average: the older the time point, the less weight the corresponding value is considered to be.
+
+**Arguments**
+
+-   `value` — Value. [Integer](../../../sql-reference/data-types/int-uint.md), [Float](../../../sql-reference/data-types/float.md) or [Decimal](../../../sql-reference/data-types/decimal.md).
+-   `timestamp` — Timestamp. [Integer](../../../sql-reference/data-types/int-uint.md), [Float](../../../sql-reference/data-types/float.md) or [Decimal](../../../sql-reference/data-types/decimal.md).
+
+**Parameters**
+
+-   `x` — Half-life period. [Integer](../../../sql-reference/data-types/int-uint.md), [Float](../../../sql-reference/data-types/float.md) or [Decimal](../../../sql-reference/data-types/decimal.md).
+
+**Returned values**
+
+- Returnes an [exponentially smoothed moving average](https://en.wikipedia.org/wiki/Moving_average#Exponential_moving_average) of the values for the past `x` time at the latest point of time.
+
+Type: [Float64](../../../sql-reference/data-types/float.md#float32-float64).

-Bit functions work for any pair of types from UInt8, UInt16, UInt32, UInt64, Int8, Int16, Int32, Int64, Float32, or Float64.
+Bit functions work for any pair of types from `UInt8`, `UInt16`, `UInt32`, `UInt64`, `Int8`, `Int16`, `Int32`, `Int64`, `Float32`, or `Float64`. Some functions support `String` and `FixedString` types.
 
 The result type is an integer with bits equal to the maximum bits of its arguments. If at least one of the arguments is signed, the result is a signed number. If an argument is a floating-point number, it is cast to Int64.

 ## bitShiftLeft(a, b) {#bitshiftlefta-b}
 
+Shifts the binary representation of a value to the left by a specified number of bit positions.
+
+A `FixedString` or a `String` is treated as a single multibyte value.
+
+Bits of a `FixedString` value are lost as they are shifted out. On the contrary, a `String` value is extended with additional bytes, so no bits are lost.
+
+**Syntax**
+
+``` sql
+bitShiftLeft(a, b)
+```
+
+**Arguments**
+
+-   `a` — A value to shift. [Integer types](../../sql-reference/data-types/int-uint.md), [String](../../sql-reference/data-types/string.md) or [FixedString](../../sql-reference/data-types/fixedstring.md).
+-   `b` — The number of shift positions. [Unsigned integer types](../../sql-reference/data-types/int-uint.md), 64 bit types or less are allowed.
+
+**Returned value**
+
+-   Shifted value.
+
+The type of the returned value is the same as the type of the input value.
+
+**Example**
+
+In the following queries [bin](encoding-functions.md#bin) and [hex](encoding-functions.md#hex) functions are used to show bits of shifted values.
+
+``` sql
+SELECT 99 AS a, bin(a), bitShiftLeft(a, 2) AS a_shifted, bin(a_shifted);

 ### Encryption Codecs {#create-query-encryption-codecs}
 
 These codecs don't actually compress data, but instead encrypt data on disk. These are only available when an encryption key is specified by [encryption](../../../operations/server-configuration-parameters/settings.md#server-settings-encryption) settings. Note that encryption only makes sense at the end of codec pipelines, because encrypted data usually can't be compressed in any meaningful way.
 
 Encryption codecs:
 
--   `Encrypted('AES-128-GCM-SIV')` — Encrypts data with AES-128 in [RFC 8452](https://tools.ietf.org/html/rfc8452) GCM-SIV mode. This codec uses a fixed nonce and encryption is therefore deterministic. This makes it compatible with deduplicating engines such as [ReplicatedMergeTree](../../../engines/table-engines/mergetree-family/replication.md) but has a weakness: when the same data block is encrypted twice, the resulting ciphertext will be exactly the same so an adversary who can read the disk can see this equivalence (although only the equivalence).

+## exponentialMovingAverage {#exponential-moving-average}
+
+Вычисляет экспоненциальное скользящее среднее за определенный промежуток времени.
+
+**Синтакис:**
+
+```sql
+exponentialMovingAverage(x)(value, timestamp)
+```
+
+Каждой точке `timestamp` на временном отрезке соответствует определенное значение `value`. Период полураспада — временной интервал `х`, через который вес значений уменьшается в 2 раза. Функция возвращает взвешенное среднее: чем старше временная точка, тем c меньшим весом считается соответствующее ей значение.
+
+**Аргументы**
+
+-   `value` — входные значения. [Integer](../../../sql-reference/data-types/int-uint.md), [Float](../../../sql-reference/data-types/float.md) или [Decimal](../../../sql-reference/data-types/decimal.md).
+-   `timestamp` — параметр для упорядочивания значений. [Integer](../../../sql-reference/data-types/int-uint.md), [Float](../../../sql-reference/data-types/float.md) или [Decimal](../../../sql-reference/data-types/decimal.md).
+
+**Параметры**
+
+-   `x` — период полураспада. [Integer](../../../sql-reference/data-types/int-uint.md), [Float](../../../sql-reference/data-types/float.md) или [Decimal](../../../sql-reference/data-types/decimal.md).
+
+**Возвращаемые значения**
+
+-   Возвращает [экспоненциальное скользящее среднее](https://ru.wikipedia.org/wiki/Скользящая_средняя#Экспоненциально_взвешенное_скользящее_среднее) за прошедшее время `x` в последний момент времени.
+
+Тип: [Float64](../../../sql-reference/data-types/float.md#float32-float64).

 ### Мутации {#mutations}
 
 Мутации - разновидность запроса ALTER, позволяющая изменять или удалять данные в таблице. В отличие от стандартных запросов [ALTER TABLE … DELETE](../../../sql-reference/statements/alter/delete.md) и [ALTER TABLE … UPDATE](../../../sql-reference/statements/alter/update.md), рассчитанных на точечное изменение данных, область применения мутаций - достаточно тяжёлые изменения, затрагивающие много строк в таблице. Поддержана для движков таблиц семейства [MergeTree](../../../engines/table-engines/mergetree-family/mergetree.md), в том числе для движков с репликацией.

+Backports changes from PR to release branch.
+Requires multiple separate runs as part of the implementation.
+
+First run should do the following:
+1. Merge release branch with a first parent of merge-commit of PR (using 'ours' strategy). (branch: backport/{branch}/{pr})
+2. Create temporary branch over merge-commit to use it for PR creation. (branch: cherrypick/{merge_commit})
+3. Create PR from temporary branch to backport branch (emulating cherry-pick).
+
+Second run checks PR from previous run to be merged or at least being mergeable. If it's not merged then try to merge it.
+
+Third run creates PR from backport branch (with merged previous PR) to release branch.

-# How to build ClickHouse on Mac OS X
-#  Build should work on Mac OS X 10.12. If you're using earlier version, you can try to build ClickHouse using Gentoo Prefix and clang sl in this instruction.
-#  With appropriate changes, build should work on any other OS X distribution.
-
-## Install Homebrew
-
-if [ -z `which brew` ]; then
-    /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
-fi
-
-## Install required compilers, tools, libraries
-
-brew install cmake ninja gcc icu4c mariadb-connector-c openssl unixodbc libtool gettext readline librdkafka
-
-# If you want to run tests
-brew install python
-sudo pip install lxml termcolor requests
-
-## Checkout ClickHouse sources
-
-#  To get the latest stable version:
-
-BASE_DIR=$(dirname $0) && [ -f "$BASE_DIR/../../CMakeLists.txt" ] && ROOT_DIR=$BASE_DIR/../.. && cd $ROOT_DIR
-
-if [ -z $ROOT_DIR ]; then
-    # Checkout ClickHouse sources
-    git clone -b stable --recursive https://github.com/ClickHouse/ClickHouse.git
-    cd ClickHouse
-fi
-
-#  For development, switch to the `master` branch.
-#  For the latest release candidate, switch to the `testing` branch.
-
-## Build ClickHouse
-
-mkdir build
-cd build
-cmake .. -DCMAKE_CXX_COMPILER=`which g++-9 g++-8` -DCMAKE_C_COMPILER=`which gcc-9 gcc-8`
-cmake --build .
-
-cd ..
-
-#  Run server:
-# build/programs/clickhouse-server --config-file=ClickHouse/programs/server/config.xml &
-
-#  Run client:
-# build/programs/clickhouse-client
-
-
-## Caveats
-#  If you intend to run clickhouse-server, make sure to increase system's maxfiles variable. See [MacOS.md](https://github.com/ClickHouse/ClickHouse/blob/master/MacOS.md) for more details.

+
+ClickHouse organized an online Meetup on October 19, 2021, hosted by our very own co-founder and CTO, Alexey Milovidov. There are a lot of new features to discuss in the 21.10 version of ClickHouse, along with many more new features coming up on the roadmap.
+
+There were over 200 attendees in person for the Meetup and 3,853 viewers online, and we want to thank everyone who attended live. You can watch the recording of the Meetup on YouTube [here](https://www.youtube.com/watch?v=W6h3_xykd2Y).
+
+Alexey Milovidov, Chief Technology Officer, welcomed and updated the community on ClickHouse Inc.'s latest news. Maksim Kita, Sr. Software Engineer at ClickHouse, started with a discussion on the new User Defined Functions (UDFs) available in 21.10. UDFs can be defined as lambda expressions using the CREATE FUNCTION command. For example:
+
+```
+CREATE FUNCTION a_plus_b AS (a, b) -> a + b
+```
+
+In addition to UDFs, there are two new table engines - Executable and ExecutablePool - that can stream records via stdin and stdout through custom scripts written in whatever language you prefer. For details, be sure to check out our [new training lesson on What's New in ClickHouse 21.10](https://clickhouse.com/learn/lessons/whatsnew-clickhouse-21.10/).
+
+You can now encrypt your data stored on S3, HDFS, external disks, or on a local disk. ClickHouse developers Vitaly Baranov and Artur Filatenkov discussed the details and benefits of encrypting your data at rest in ClickHouse. Vitaly presented the new full disk encryption feature and Arthur presented column-level encryption.

+
+![Arthur Filatenkov](https://blog-images.clickhouse.com/en/2021/clickhouse-october-moscow-meetup/arthur-filatenkov.jpg)
+
+Alexey then spent 40 minutes discussing some of the amazing new features on the ClickHouse roadmap, including:
+
+* ClickHouse Keeper: a new C++ coordination system for ClickHouse designed as an alternative to ZooKeeper
+* Support for working with semi-structured data, including JSON objects with arbitrary nested objects
+* Asynchronous insert mode - now you can insert data without batching!
+
+After the talk, Alexey took questions from users on:
+
+* How to parse User-Agent in ClickHouse 
+* Is it true that ClickHouse developers have a ClickHouse tattoo
+
+![YAML Configuration](https://blog-images.clickhouse.com/en/2021/clickhouse-october-moscow-meetup/yaml-configuration.jpg)
+
+* If you are excited about ClickHouse, be sure to join us on [Telegram](https://t.me/clickhouse_en)
+* We also have a community Slack workspace be sure to join [here](https://clickhousedb.slack.com/).
+* If you are new to ClickHouse and want to see it in action, check out our [Getting Started lesson](https://clickhouse.com/learn/lessons/gettingstarted/).

+
+We're continuing our monthly release cadence and blog updates at[ ClickHouse, Inc](https://clickhouse.com/blog/en/2021/clickhouse-inc/). The 21.11 release includes asynchronous inserts, interactive mode, UDFs, predefined connections, and compression gains. Thank you to the 142 committers and 4337 commits for making this release possible. 
+
+Let's highlight some of these new exciting new capabilities in 21.11:
+
+## Async Inserts
+
+New asynchronous INSERT mode allows to accumulate inserted data and store it in a single batch utilizing less disk resources(IOPS) enabling support of high rate of INSERT queries. On a client it can be enabled by setting `async_insert` for `INSERT` queries with data inlined in a query or in a separate buffer (e.g. for `INSERT` queries via HTTP protocol). If `wait_for_async_insert` is true (by default) the client will wait until data will be flushed to the table. On the server-side it can be tuned by the settings `async_insert_threads`, `async_insert_max_data_size` and `async_insert_busy_timeout_ms`. 
+
+**How does this help our ClickHouse Users?**
+
+A notable pain point for users was around having to insert data in large batches and performance can sometimes be hindered. What if you have a monitoring use case and you want to do 1M records per second into ClickHouse; you would do large 100k record batches, but if you have 1,000 clients shipping data then that was hard to collect these batches to insert into ClickHouse. Historically to solve for this you might have to use Kafka or buffer tables to help with the balancing and insertion of data.
+
+Now, we've introduced this new mode of Async inserts where you can do a high rate of small inserts concurrently and ClickHouse will automatically group them together into batches and insert it into the table automatically. Every client will get an acknowledgement that the data was inserted successfully.
+
+## Local Interactive Mode
+
+We have added interactive mode for `clickhouse-local` so that you can just run `clickhouse-local` to get a command line ClickHouse interface without connecting to a server and process data from files and external data sources.
+
+**How does this help our ClickHouse Users?**
+
+What if you have an ad-hoc use case that you want to run analytics on a local file with ClickHouse? Historically, you'd have to spin up an empty ClickHouse server and connect it to the external data source that you were interested in running the query on e.g. S3, HDFS, URL's. Now with ClickHouse Local you can just run it just like a ClickHouse Client and have the same full interactive experience without any additional overhead steps around setup and ingestion of data to try out your idea or hypothesis. Hope you enjoy!
+
+## Executable UDFs
+
+Added support for executable (scriptable) user defined functions. These are UDFs that can be written in any programming language. 
+
+**How does this help our ClickHouse Users?**
+
+We added UDFs in our 21.10 release. Similar to our October release we're continuing to innovate around the idea of making it more user friendly to plug in tools into ClickHouse as functions. This could be you doing an ML inference in your Python script and now you can define it as a function as available in SQL. Or, what if you wanted to do a DNS lookup? You have a domain name in a ClickHouse table and want to convert to an IP address with some function. Now just plug in an external script and this will go process and convert the domain names into IP addresses.
+
+## Predefined Connections
+
+Allow predefined connections to external data sources. This allows to avoid specifying credentials or addresses while using external data sources, they can be referenced by names instead. 
+
+**How does this help our ClickHouse Users?**
+
+You're just trying to connect ClickHouse to another data source to load data, like MySQL for example, how do you do that? Before this feature you would have to handle all the credentials for MySql, use the MySQL table functions, know the user and password permissions to access certain tables, etc. Now you have a predefined required parameters inside the ClickHouse configuration and the user can just refer to this by a name e.g. MongoDB, HDFS, S3, MySQL and it's a one-time configuration going forward. 
+
+## Compression
+
+Add support for compression and decompression for `INTO OUTFILE` and `FROM INFILE` (with autodetect or with additional optional parameter).
+
+**How does this help our ClickHouse Users?**
+
+Are you just looking to import and export data into ClickHouse more easily if you have compressed data? Before this feature you had to manually specify compression of input and output data into ClickHouse and even for stream insertion you'd still have to manage the decompression there too. Now, you can just write it as a file e.g. mytable.csv.gz --- and, go!
+
+In the last month, we've added new free Training modules including a What's New in 21.11. Take the lesson [here](https://clickhouse.com/learn/lessons/whatsnew-clickhouse-21.11/).
