XPS 9360 BIOS 2.5.0 refreshed, but no version bump?

First, I'm really struggling with the new forum layout.
I can't  find posts I did last year... Not linked to my profile anymore...

On topic:

I'm running linux so to view my bios:
dmidecode output gives:

        Vendor: Dell Inc.
        Version: 2.5.0
        Release Date: 12/12/2017

But now i read on the Dell Bios website:

XPS 13 9360 2.5.0 BIOS
Release date: 29 dec 2017
Last changed: 11 jan 2018

In terms of version I would say I'm on current version, but according the release dat that can't be correct.

My question: is this still the same bios, or is it not, but the version hasn't changed?

The noted fixes seem inportant enough...

Fixes:
- Updated Intel ME Firmware to address security advisories INTEL-SA-00086 (CVE-2017-5705, CVE-2017-5708, CVE-2017-5711 & CVE-2017-5712) & INTEL-SA-00101(CVE-2017-13077, CVE-2017-13078 & CVE-2017-13080)
- Update to the latest CPU microcode to address CVE-2017-5715

Re: XPS 9360 BIOS 2.5.0 refreshed, but no version bump?

 It's still the same BIOS from December 29th as checksums didn't change and they still match. I'm confused about this "update" too, maybe some typos on the webpage were fixed.

UPD: dmidecode shows 12/12/2017 for me too, so it's the same BIOS image:

Vendor: Dell Inc.
Version: 2.5.0
Release Date: 12/12/2017

ha ha!

OK guys, you all need to know that release dates on Dell support website are absolutely meaningless!

You should'nt pay attention to it as it will only confuse you. (in fact release dates are changed every day for my XPS 13!!!)

Only Version number is correct.

I can't find an explanation why on earth Dell are always updating release date on already released drivers... but hey, they do!

@DELL: please stop updating release date if there is no real update for a driver/bios/software.

Thanks for reminding to verify the checksums, could have thought of that myself.
And you are right, they haven't changed.

As I recall there wasn't many info from Dell on the 2.5.0 update when it was first released.
CVE-2017-5715 got public on January 3, 2018 as Spectre.
So my best guess is that they released this urgent update with the fix for Spectre, but didn't mention it.
And that the change on 11jan 2018 is that they added the info for CPU microcode to address CVE-2017-5715.

If that's correct Dell did a great job.
Many people are still waiting for a Bios fix from their hardware vendor, we are not.
