Plug in charger to MacBook.
Make sure MacBook is on wall power too .
Reboot Mac, and it’ll update . Done it on 3 now flawlessly

Of course they do. So does every smart light bulb from Hue or so.
Processors nowadays, especially those used to handle such devices as USB-C chargers, light bulbs, smart plugs etc. only cost some cents.
Probably they all use some sort of ARM Cortex M-series porocessor.
How do you check the firmware on about mine shows 0.0.0.0
I thought the Chargers were eliminated this past weekend.
These days it's a safe bet to assume that every electronic device contains at least a microcontroller. It's an easier and cheaper way to build electronics now, rather than hardwiring a bunch of discrete logic. I believe in this case it's used to negotiate sending amounts of power above the default.
IIRC Lightning cables (official ones, at least) also contain a microcontroller to negotiate which lines of the cable are used for which signals.
I think it’s arrogance to the extreme.
“You stupid, stupid customer! All you do is buy our products! You don’t deserve to know whether we fixed a bug that’s been affecting your daily work, you pathetic flea.”
This is yet another reason why Apple continues to fail miserably in enterprise computing. “What’d you fix?” “We’re not telling! Nyah, nyah, nyah, stupid IT guy! We’re too good for you! Ha!”
And… if Apple doesn’t even have a list of what they fixed and confirmed fixed… well that’s WAY worse.
If you plug a MagSafe charger into an iPhone, and then put the iPhone on the MagSafe pad, does it power your iPhone forever?
(Actually, I would expect the software in the MagSafe charger to specifically shut down this case.)
Agreed, and yet there are people who seem to want to check constantly if and when a firmware upgrade has occurred and look for ways to force it to happen. More often than not, the upgrades bring no discernible change in day to day use, so who cares its it takes a day, a week or a month?
Been looking everywhere for this info but does anyone know what specific voltages the 2nd gen mage safe charger needs to achieve 25w? I know the doc says 30w charger but we all know the voltages are what matter. So many adapters out there with screwy voltages sold as 30w.
For example the apple 35w USBC dual port adapter I don’t think will give you 25w to the MagSafe adapter because it requires a voltage it doesn’t support but I can’t find this info anywhere!!

Hell, many throw away vapes now have full blown RISC-V or even ARM procs in them
No. For your scenario, the update is pushed to the charger though the puck end from your iPhone, not the USB-C end from your Windows PC/laptop. Just put your iPhone on the MagSafe charger and let it sit overnight (which is typically what people do anyway when they go to bed.)
For those where it's just showing 0.0.0.0, it usually means that the charger is in an update state. If you leave it alone, plugged into power with your iPhone attached, it'll go back to showing a version number eventually. Sometimes, when it shows that 0.0.0.0 version, it can also be missing other fields entirely, like the serial number and hardware version fields. They should all reappear eventually if you just leave it alone.

for the past decade+, even the most simple of devices are built around programmable controllers. And that implies software stored within a memory device. It is now more common for this software to be field updateable.
So, according to the linked MagSafe How-To, with my MagSafe charger plugged into a AC adapter, not a Mac, I can access and update the firmware from my iPhone sitting on the MagSafe charger?
I'd have guessed that I'd need to plug the MagSafe into a Mac, but that's not what the site is saying.
This would mean MagSafe has Bluetooth or Wi-fi connectivity. I've never heard this before. Otherwise how would an iPhone update MagSafe's firmware?

It does also bring to mind a suggestion I had a couple of years ago for Apple to build in something of a super AirDrop into MagSafe chargers and iPhones. Surely the millimeter proximity involved could speed up AirDrop to much, MUCH faster speeds than it currently works at several meters.

Perhaps Apple has updated the support article [link] since you last looked, but they now discuss it there.
It requires an adapter that supports 15V/2.0A or higher.
All chargers long before this one had updates, you just didn't know it because it took place in the factory. This is why every single device, piece of software, etc has version numbers on it. Bugs are found, updates are fixed, people buy the new ones.
Being able to update a charger is a good thing, it means whatever is fixed you get the fix instead of being stuck with the bugged one.
weird, mine displayes as Firmware 0.0.2.58 on iOS, or version 2.58 on macOS
