What's New in Altair AI Hub 2025.1.0?

Released: 15th May 2025

Version 2025.1 is compatible with version 10, 2024, and 2025.0. When you’re still on version 9, then upgrading to 2025 is a major version upgrade. Please make sure to read the upgrade from AI Hub 9 migration instructions!

The following describes the enhancements and bug fixes in AI Hub 2025.1.0:

AI Hub Server

Enhancements

Service endpoints of Scoring Agents / Web API Agents have been enhanced:
- GET requests are now supported
- Endpoints can be requested with arbitrary binary data
- Endpoints can return arbitrary binary data
Added ability to synchronize Altair Python SDK extensions located inside AI Hub's home directory under resources/python-sdk-extensions
- The Python SDK extensions require the Java extension Python Extension Loader (PEL)
- Synchronization mechanism is identical to other resources (licenses, Java extensions, ...)
- By default, the PEL is using the default synchronization folders to pick up Altair Python SDK extensions, this can be overridden by setting PYSDK_PEL_EXT_LOC to a different location
- Added/modified the following properties to AI Hub
  - sync.python-sdk-extension-exclusions (defaults to an empty list)
  - sync.tmp-dir.python-sdk-extension-dir (defaults to ${sync.tmp-dir.base-dir}/python-sdk-extension)
  - rapidminer.python-sdk-extension-dir (defaults to ${aihub.home-dir}/resources/python-sdk-extensions)
  - sync.execution-context-exclusions to ["extensions/workspace", "AIToolsDevkit"] which was previously defaulting to ["extensions/workspace"]
- Added the following properties to Web API Agent / Scoring Agent
  - scoring-agent.sync.python-sdk-extensions.enabled (defaults to true for Web API Agents, false otherwise)
  - scoring-agent.sync.python-sdk-extensions.clean-before (defaults to true)
  - scoring-agent.rapidminer.python-sdk-extension-dir (defaults to ${scoring-agent.home-dir}/resources/python-sdk-extensions)
- Added the following properties to Job Agent
  - jobagent.sync.python-sdk-extensions.enabled (defaults to true)
  - jobagent.sync.python-sdk-extensions.clean-before (defaults to true)
  - jobagent.container.python-sdk-extensions-dir (defaults to ${jobagent.home-dir}/resources/python-sdk-extensions) which is filling the python-sdk-extension-dir to the Job Container automatically
- Added the following properties to Job Container
  - python-sdk-extension-dir (defaults to provided setting by Job Agent)
Allow to enable/disable indexing of to-be-synchronized files (to Job Agents, Web API Agents), added the following properties to AI Hub which have been enabled by default in prior versions
- sync.extension-enabled (defaults to true)
- sync.python-sdk-extension-enabled (defaults to true)
- sync.libs-enabled (defaults to true)
- sync.execution-context-enabled (defaults to true)
- License synchronization is automatically determined by the license.mode property
Web API Agents exit code is now configurable when a sync request is incoming, scoring-agent.sync.sync-shutdown-exit-code defaults to -1
Added a web interface to view status of internal synchronization service and an action to trigger re-synchronization for admins
Added a web interface for administrative operations like shutdown for admins
Added properties to AI Hub to control the timing and exit code of manually invoked shutdowns
- aihub.shutdown-delay defaults to 5000 milliseconds
- aihub.shutdown-exit-code defaults to -1
Deployments are disabled automatically, in case of missing required extensions
Deployments can be disabled manually by the user (via UI)
Dependency updates
- Upgraded to Spring Boot 3.4.5
- Bump h2 version from 2.1.214 to 2.3.232
- org.apache.commons:commons-text from 1.13.0 to 1.13.1
- com.google.guava:guava from 33.4.7-jre to 33.4.8-jre
- Front-end dependencies

Fixed

Web API Agents and Scoring Agents maintain their resulting IOContainer objects on disk; only input data is properly cleaned up after execution
Front-end for Endpoints crashing due to 3rd party library version collision
Fixed data set response in Web API and Scoring Agent to capture
- missing nominal values which are now represented as null (before: "?")
- missing date values which are now represented as null (before: "new Date(0)")
Fixed cached repository inconsistencies
