What happened to the Signing Tool?

I recently download and installed the latest version of STMCube Programmer and I see that the Signing Tool is now gone.  In its place is the STM32 Trusted Package Creator.  Unfortunately, support for the STM32N6 appears to be missing.  Where may I find the old signing tool?

Hi ​@Neuraleanus,

Signing tool is indeed there, there just have been a change starting from STM32CubeProgrammer v2.21. Please refer to this thread: SigningTool for STM32N6 in STM32CubeProgrammer v2.21.0 | Community.
