# Altinity Stable Build for ClickHouse® 23.8

It has been a while since we certified [Altinity Stable Build for ClickHouse 23.3](https://altinity.com/blog/altinity-stable-clickhouse-23-3-has-arrived). Since then ClickHouse has advanced rapidly. More than 300 contributors from companies all around the world submitted 2200 pull requests with new features and improvements. We spent four months testing and gathering early adopter experience to gain confidence to recommend 23.8 for production use and make sure upgrades go smoothly. As of 23.8.8 we are confident in certifying 23.8 as an Altinity Stable Build. In fact, we have published the release right before the New Year, so it is already in active usage by our customers. 

We collected detailed release notes for 23.8 Altinity Stable at [Altinity Documentation Site](https://docs.altinity.com/releasenotes/altinity-stable-release-notes/23.8). There are a lot of new features, but also many things that changed their behavior, so check them carefully before upgrading.

## Changes in Altinity Stable Build Compared to Upstream Build

[Altinity Stable Builds](https://altinity.com/altinity-stable/) for ClickHouse are open source and are based on the upstream LTS versions. Altinity Stable 23.8.8 is based on upstream 23.8.8.20-lts, but we have additionally back-ported several important fixes:

- Fix key analysis (with set) for Merge engine [#54905](https://github.com/ClickHouse/ClickHouse/pull/54905) via [#341](https://github.com/Altinity/ClickHouse/pull/341)

- Fix partition pruning of extra columns in set [#55172](https://github.com/ClickHouse/ClickHouse/pull/55172) via [#342](https://github.com/Altinity/ClickHouse/pull/342)

- Fix FINAL produces invalid read ranges in a rare case [#54934](https://github.com/ClickHouse/ClickHouse/pull/54934) via [ #343](https://github.com/Altinity/ClickHouse/pull/343)

- Fix incorrect free space accounting for least_used JBOD policy [#56030](https://github.com/ClickHouse/ClickHouse/pull/56030) via  [#344](https://github.com/Altinity/ClickHouse/pull/344)

- Fix ALTER COLUMN with ALIAS [#56493](https://github.com/ClickHouse/ClickHouse/pull/56493) via  [#345](https://github.com/Altinity/ClickHouse/pull/345) *(backported into 23.8.9 upstream)*

- Disable `system.kafka_consumers` by default due to possible live memory leak [#57822](https://github.com/ClickHouse/ClickHouse/pull/57822) via [#346](https://github.com/Altinity/ClickHouse/pull/346) *(backported into 23.8.9 upstream)*

## Let’s Install!

Linux packages can be found at [https://packages.clickhouse.com](https://packages.clickhouse.com) for upstream builds, and at [https://builds.altinity.cloud](https://builds.altinity.cloud) for Altinity Stable builds.

Docker images for the upstream version should be referenced as `clickhouse/clickhouse-server:23.8.8.20`

Altinity Stable build images are available as `altinity/clickhouse-server:23.8.8.21.altinitystable`

For more information on installing ClickHouse from either the Altinity Builds or the upstream builds, see the [ClickHouse Altinity Stable Release Build Install Guide](http://docs.altinity.com/altinitystablebuilds/stablequickstartguide/).

Please contact us at [info@altinity.com](mailto:info@altinity.com) if you experience any issues with the upgrade.

You don’t have to install today, since this build has a three year maintenance tail. We’ll support it through 27 Dec 2026.
