6.2.0

2026-07-27

​
Summary

The main changes in 6.2 are:
  • Upgrade to Java 25
  • Upgrade to Spring Boot 4, including Spring 7 and Jackson 3
  • Switch to SLF4J for logging
Many smaller changes are also part of this release. See the changelog for the full list. A migration note provides detailed guidance, including an automated migration process using OpenRewrite recipes.

​
Java upgrade

The new baseline is Java 25, bringing the latest JDK improvements to Atoti.

​
Spring upgrade

The new baseline is Spring 7 and Spring Boot 4, because open source support for Spring Boot 3 ends in June 2026. This upgrade also brings Jackson to version 3.

​
SLF4J

Atoti Server now logs through SLF4J, the de facto standard logging facade for Java, instead of JUL (java.util.logging). Routing Atoti Server logs into your logging framework of choice is now more direct. See the migration notes for the logging dependencies to review when upgrading.

​
New Features

  • Added Copper Join Optimization, an experimental optimization that speeds up Copper joins with a selective filter on the joined table.

​
Other changes

  • ClickHouse 26.03
  • Databricks Runtime: 17.3
  • MSSQL Server 2019
