What's new in Rapidminer AI Python SDK 2.0
Released: July 01, 2026
The new Rapidminer AI Python SDK (rapidminer-ai-sdk) package has superseded the now deprecated Altair AI Tools Python Devkit (altair-aitools-devkit)! All functionality has fully transitioned into the new package, so please use rapidminer-ai-sdk going forward!
Functionality-wise, the Rapidminer AI Python SDK 2.0 and the deprecated Altair AI Tools Devkit 1.2 are identical as this release marks the switch to the new package.
Since Python 3.12 has been out for almost three years by now and 3.11 will be EOL next year, we decided to bump the minimum required Python version to 3.12 when building new extensions.
Security improvements
Since Python extensions by nature execute Python code, and arbitrary Python code can do arbitrary things, we have added support for signing Python extensions via the trusted Rapidminer code signing certificate. Extensions signed with it indicate that they have either been developed by us directly, or at least have been deemed safe by us after inspection. This can be coupled with new admin settings which can be used to enforce e.g. only usage of such signed extensions and blocks any attempt by users to load unsigned extensions (which can come from unverified sources).
Introducing UX improvements
Rapidminer AI Python SDK 2.0 introduces support for better error messages (including translation support) for expected events during operator runtime (e.g. an invalid combination of settings, expected connectivity problems, etc.) This will be very useful to tell the user about configuration or state problems that can be expected - so they no longer appear as scary error messages that normally indicate actual bugs.
In addition to that, we have also introduced the capability for developers to define colors for the Python operators, which aligns with the existing capability of Java-based operators to easily visually distinguish different operator categories.
