Workflow Engine 12.4.0

March 28, 2024

Overview

Workflow Engine 12.4.0 is a validation and stability release. Workflow Engine packages already target .NET Standard, so .NET 8 compatibility existed earlier; in this release we fully tested and confirmed production use with .NET 8 across official samples and runtime scenarios.
