pSeven Enterprise v2024.04 Release

pSeven development team announces the release of pSeven Enterprise v2024.04, a new version of a low-code cloud-native collaborative platform for building, deploying and operating different models and processes at scale. This release contains many changes, the most important of which are below.


  • Design space exploration block (beta):
    • You can track the progress of the study while it runs, using the new Designs.html report with interactive plots of the evaluation history.

      LHS and other DoE techniques recognize the Maximum batch size setting

    • Enabled the internal modeling of linear responses in DoE techniques and in Adaptive design for GP (except the Adaptive responses).
    • Better visible saving notification: the save button is being disabled and changes its label.

  • Python script block:
    • Updated a number of modules provided by the block. Certain updates might require you to review your scripts so as to keep compatibility with the updated modules.

Deployment and administration

  • Updated the pSeven Enterprise authentication service (Keycloak) to resolve several related CVE issues.
  • Resolved several CVE issues in the embedded Python.

User block development

  • Updated a number of Python modules in the block runtime environment.
  • Fixed a regression issue from v2023.03 where adding the DEV tag to your block did not disable the block code caching on Windows nodes.


  • Design space exploration block (beta):
    • Fixed an issue with batch mode in Gradient-free optimization where, if you do not set the batch size limit, the block always output batches of size 1 (containing a single point only).
    • Fixed an issue with incorrect point classification in Designs.csv where the "feasible" and "optimal" columns could contain 1 for infeasible points (both should be 0 in this case).
    • Fixed an issue with results where, if no feasible designs were found, the block added all points to the Feasible designs sample.
  • Uncertainty quantification block (beta):
    • Fixed an issue where it was possible to save the block with an invalid value of the Random seed option, which caused an error when running the workflow.
  • Python script block:
    • Fixed a regression issue from v2024.01 with using Numba where the block raised ImportError due to the outdated llvmlite dependency.
    • Fixed an issue where manually stopping the block caused a workflow error, so the run status was set to FAILED (should be INTERRUPTED), and api.interrupted() in the block's script did not catch the stop request as intended.
  • Fixed an issue with workflow references where pSeven Enterprise failed to open a main workflow containing references, if that main workflow was copied from another deployment.

pSeven Enterprise v2024.04 also includes other various performance and security improvements and minor bug fixes — please check the release changelog for a full list. You can also contact us to get more information and pSeven Enterprise updates.
