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 4.0.0 and Nintex Bot 18.0.0: May 26, 2026

Nintex RPA Central 4.0.0 new features and fixed issues

New features

  • Added support for the new Bot Role Licensing model which supports assigning Nintex Bot roles to bots as Developer, Attended, or Unattended Bots. For more details on the new licensing model, contact your Nintex Account Manager.

  • Added support for running multiple instances of a botflow, limited to the number of available and assigned bots. For more information, see Instance Management.

Fixed issues

  • Fixed an issue where botflow permissions could not be assigned to certain botflows in Nintex RPA Central 3.2.0.

  • Improved memory usage to reduce high memory consumption.

  • Updated the Nintex RPA Central API behavior so that an instance is paused before it is terminated.

Nintex Bot 18.0.0 new features and enhancements, fixed issues, and known issue

New features and enhancements

  • Added support for the new Bot Role Licensing model allowing Nintex Bot to run as a Developer, Attended, or Unattended Bot. For more details on the new licensing model, contact your Nintex Account Manager.

    Note: Nintex Bot still fully supports existing Licensing models (Enterprise, Standard, and Bot Editions).

  • Added support for a new Rocket iSeries Java emulator, including related enhancements and defect fixes.

  • Added a new Set Variables action that allows setting the values of multiple variables in a single action.

  • Added an option to search all text nodes when searching a UI Automation (UIA) list or combo box.

  • Optimized the Open Data action to improve execution speed.

  • Automatically applies the Excel registry fix for unattended bots when running them from Nintex RPA Central, removing the need for user prompts.

  • Improved blocked iFrame detection in the Nintex RPA Chrome Extension to make Chrome target rectangle calculations more robust on pages that include blocked iFrames.

Fixed issues

  • Fixed an issue where the Credential Exists action did not work as expected.

  • Fixed an issue where a bot window could become unresponsive due to a background Save prompt not appearing in the foreground.

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.
