Changelog

Update instructions

Update all Workflow Engine packages to 17.2.0.

Features

• Added a persist parameter to the SetActivityWithExecutionAsync method. You can now pass implicit parameters with the persistence storage type.
• Introduced the OverrideRuleProvider method in the base plugin to allow overriding the plugin's rule provider implementation.
• Added the GetApproverIdentityId delegate to the Parallel Approvers mechanism in the base plugin. This allows customizing how the IdentityId is retrieved based on the FillApproversUsers action parameter.
• Added the RequiredApprovalsNumber setting to the Parallel Approvers mechanism in the base plugin. This allows specifying the number of approvals required to complete parallel approval.

Enhancements

• PostgreSQL now supports creating a version history table in a schema other than public when using automatic migrations. To do this, specify the desired schema in the provider arguments.

Bug fixes

• Fixed a NullReferenceException caused by the FillApproversRoles action in the Parallel Approvers mechanism of the base plugin.
• Fixed an issue where data in custom activities was not displayed when opening the form.
