I've upgraded a Thinkpad T490 to BIOS version 1.44 seemingly succesfully but the Embedded Controller Program version is still showing the original version and not what the update README promised.
Is the README correct and the same cab-file should contain the ECP update as well? Has anyone upgraded on Windows and actually received the ECP 1.09 update?

I'm not a linux guy but my understanding is that linux uses a capsule update method which is only for the BIOS. There is no capsule update for ECP. So I think you would need to build the bootable USB key and update BIOS/ECP that way. I know this isn't a very good answer and the readme doesn't explain this, but the version information with change history seems copied from the Windows readme.
I can tell you that using the flash-from-Windows package updates both BIOS and ECP.
