Nintex RPA LE release notes

Follow this page and the Nintex RPA Community blog to stay updated on product release information.

Important: 

If you are upgrading from a Nintex RPA Central version prior to 2.0 and a Nintex Bot version prior to version 17.3.0, Nintex recommends planning a maintenance time to: 

  1. Terminate all botflow instances.

  2. Unpublish all botflows that are scheduled to run within your planned maintenance time window. For more information, see Edit a botflow in Nintex RPA Central. You can also back up or export key botflows. For more information, see Backup and restore and Botflow Menu.

  3. Upgrade Nintex RPA Central. For more information, see Install Nintex RPA Central.

  4. Upgrade Nintex Bots. For more information, see Install and configure a Nintex Bot.

The Nintex RPA Central 2.0 and above releases do not include support for processing datasets in Nintex RPA Central. However, you can still process datasets with Nintex Bots. If you have a job with a dataset that was configured in Nintex RPA Central, and you are upgrading to Nintex RPA Central 2.0 or above, the botflow will stop working. You can let the dataset job complete first before upgrading to Nintex RPA Central 2.0 or you can upgrade to Nintex RPA Central 2.1 or above (recommended).

Nintex RPA Central 3.3.0 and Nintex Bot 17.20.0: September 25, 2025

Nintex RPA Central 3.3.0 new features

New features

  • You can now view the entire history of a botflow to which you have permission, including information about what previous version the botflow was based on, its description, its active status, who created it, and when it was created. For more information, see View botflow version history.

  • You can limit the number of saved botflow versions per botflow. Enforcing a version limit restricts each botflow to a maximum of 999 versions. When the limit is reached, you cannot save new versions of the botflow until you delete existing versions or increase the limit. For more information, see Botflow versioning.

  • You can view the used and available database storage limits on your server. For more information, see Database storage.

Nintex Bot 17.20.0 new feature, enhancements, fixed issues, and known issue

New feature

  • You can save and import botflows as new versions. For more information, see Menu Bar.

Enhancements

  • The Nintex RPA LE Unlocker has been updated to resolve erroneous lock errors. For more information, see Download files.

  • Ability to write Start Diagnostics and Stop Diagnostics logging information to an output file that you specify.

  • The Click and Send Value actions are improved to bring the container Google Chrome window of targeted elements to the top order.

  • If Nintex Bot detects an issue that is preventing Excel support, the Registry Key is now automatically repaired without prompting you with a warning message, saving you clicks and time.

Fixed issues

  • When an Error Task is executed and an action fails, execution now stops gracefully without closing the botflow or clearing the run stack. The execution pointer remains positioned on the failed action, allowing you to investigate and resolve the issue. Nintex RPA Central is also explicitly notified that the botflow needs attention by sending an error signal.

  • Fixed an issue where datasets with leading/trailing spaces in column headers (e.g., " Name " instead of "Name") are accepted during import but fail validation during publishing due to strict schema comparison.

  • Nintex Bot no longer freezes when multiple instances of it are open.

  • The Watch view has been fixed so that changes to variables are once again highlighted in the Variables view.

Known issue

  • Boxing may not work correctly in Google Chrome when targeting the Print dialog with UIA on Windows Server 2019. We recommend upgrading to Windows Server 2022, as it has performed very well in our internal tests and does not exhibit this issue. Windows Server 2022 also provides you with improved performance and speed.
