Altinity Stable® Build for ClickHouse® 24.8

Altinity Stable® Build for ClickHouse® 24.8 is now available! As Altinity users are aware, Altinity Stable Builds are based on ClickHouse Long Term Support releases and maintained for three years. We build them for organizations who value stable operation without major upgrades for long periods of time. 

Version 24.8 Release Summary

It has been a while since we certified Altinity Stable Build for ClickHouse® 24.3. Since then, development rapidly progressed in the ClickHouse GitHub project. More than 250 contributors from companies all around the world submitted 2400+ pull requests with new features and improvements. We spent several months testing the new version and tracking fixes merged to the 24.8 LTS branch. We also collected early adopter feedback on upgrades as well as feature changes that affect production use. As of version 24.8.11, we are confident in certifying 24.8 as ready for use. 

Detailed release notes for Altinity Stable Build 24.8 are available on the Altinity Documentation Site. There are a lot of new features, but also many behavior changes, so check the release notes carefully before upgrading. In particular, some ClickHouse functions that have existed forever, like neighbor, runningDifference and runningAccumulate, are now deprecated in favor of more advanced window functions. Analyzer, which was enabled in 24.3, has got a lot of fixes and improvements, so it is now safe to use. Please test upgrade carefully and read the known limitations. Also check the ClickHouse® Upgrade E-book, which provides guidelines for upgrading ClickHouse databases.
