Orion Platform Version

Release Date

End of Support





































This table does not cover versioning of all subcomponents in Orion.


Compatibility Notes

Although releases are supported for one year, Orion maintains high levels of compatibility between versions. However, the following notes should be kept in mind.

  • Old Cubes may not be able to be connected to newer Cubes if the Floe specification version is mismatched.

  • There may be external reasons involving pip or 3rd party dependencies that prevent an old Floe package from being uploaded.

  • Newer versions of Orion Platform may not run against older Orion stacks, and they will raise an error if they require a new API or version of an API.

Orion 2021.1.1 introduced a check on the minimum version of Orion Platform for new Floe package uploads.

Version 2023.3.1 Highlights for Cube and Floe Developers

Orion Integration, Version 2023.3.1

The following dependencies should be observed by Cube and Floe developers.

















Orion Client

  • Updated example docker files were added with Amazon Linux 2023 and Ubuntu 22 commands.

  • WorkFloeJob.start() now accepts the notify=True flag to send a job completion email.

  • ocli datasets download now supports the –fieldlist argument to optionally export only select dataset columns. This comma-delimited list can contain either column names or column IDs.

  • OrionSession.delete_resource and ocli TYPE delete now support an immediate flag for files, datasets, collections, and projects.

  • Orion server minimum version has been upgraded to 19, thus requiring use of an Orion 2023.3.1 stack.

  • ocli jobs summary-export has been added to generate a job summary CSV file for an organization according to the request parameters. See Retrieving Summary of Jobs Within an Organization.

Bug Fixes

  • When you share a job via orionclient with session.share_resource (WorkFloeJob_instance, project_id), other members of the project can see the job in the UI. There are cases, however, where a user has access to a job but not the underlying Floe (e.g., a custom Floe that was not shared). The user could see the job but reached an uninformative blank screen when they clicked on it. The action now produces an error message.

Orion Platform

  • Columns can now be optionally ignored when exporting datasets to files. This functionality is available only in Orion.

  • A bug has been fixed in which floes using the RecordsToFileConverter Cube produced bloated files when only in Orion.

  • A bug has been fixed in which Floes using the RecordsToFileConverter Cube produced bloated files when exporting to CSV.


  • A new Cube parameter, max_backlog_wait, has been added. This parameter specifies the maximum number of seconds a Cube will be backlogged on a scaling group before being reevaluated for placement on another scaling group.

Version 2023.2.1 Highlights

  • Version 2023.2.1 includes a host of performance and stability improvements.

  • Package ingestion within Orion has been improved.

    • The environment log is now available during processing.

    • Log messages are clearer, with timestamps and phase timing.

    • Conda error messages are now more fully preserved.

  • Support for Python 3.11 has been added.

  • Support for docker-based Orion packages based on Amazon Linux 2023 (AL2023) and Ubuntu 22 (ubuntu22) has been added.

Orion Integration, Version 2023.2.1

  • The dependency attrs>=23.0.0,<24.0.0 is pinned to avoid an upstream RuntimeWarning.

  • Python ≥ 3.9 is required.



  • A new cube parameter pids_per_cpu_limit has been added. This parameter allows users to configure the amount of available pids (processes/threads) in a cube.

Orion Client

  • Serial cubes will now retry http codes 409, 429, 460, 500, 502, 503, and 504 indefinitely

  • File download uses helper to check for incomplete download, retries three times

  • Project tags are tags on resources in Team Data on the Project Data page. They are visible to all project members and are colored pink in the user interface. Any member of a project can now add project tags to any resource in Team Data. Resources are now searchable via their project tags in the Orion user interface and with Orion Client. Tags are managed with ocli jobs commands.

Orion Platform

  • Molecule titles are now preserved when exporting records to CSV format.

  • Conversion of datasets to CSV has been streamlined by removing the need to read all records prior to conversion.

  • A nonprimary molecule field is used if available when a primary molecule field is not present when converting a record to an OEMol.

  • DatasetReader cubes may now be used inside or outside of a CubeGroup without the need to set fast_read.


  • Placeholders are now written within OEFields instead of images when converting records to molecular file formats.

  • Columns containing primary molecules are now added as the first column when exporting datasets to CSV files, with their titles exported as the second column.

Version 2023.1.2 Highlights

  • Version 2023.1.2 is a maintenance release containing performance and stability improvements developed at OpenEye.

  • Python ≥ 3.9 is required.

Orion Integration, Version 2023.1.2

  • The dependency requests==2.29 is pinned to avoid conflicts.

  • A memory leak was causing large numbers of simultaneous jobs to fail. The leak, now fixed, could cause failure with ≥ 100 jobs running simultaneously. A symptom was a message with:

    [...., State=Suspect] removed: Error[NoError]]


Orion Client

  • We have modified rate limiting. We have added a mechanism to help the Orion client tell if it is running in Orion as a serial cube or as a parallel cube. If the current client is a parallel cube running in Orion, retries are limited to 2; if the current client is a serial cube, retries continue indefinitely.

Orion Integration, Version 2023.1.1
