Is Thinkpad W520 still supported w/ bios security fixes?

Hi, I own a W520 and compared W520 and W530 bios update history and I see that the latest security fix* for  theW530 bios was not shipped to W520. Also Lenovo hasn't revealed the type of vulnerability that was fixed in W530 machines and not on W520 if applicable.

So is W520 officially supported and if yes when will be these fixes backported? Thanks for the reply.



<2.73> UEFI: 2.73 / ECP: 1.13 - [Important] Update includes a security fix. - (Fix) Fixed an issue where BIOS silent update might fail with system account

I do not see any listing for the ThinkPad W520 on the Lenovo EOL page at, but it could be that it just hasn't been added.  On the other hand the last download I see for the W520 at is from February of this year.
