On the PCB as in v1.1, v1.2 etc.?
That didn't happen when the A+ gained an extra 256MB
or the Pi2 changed to a different generation of SoC or the Pi3B moved to a new revision of the SoC.
My bad it did, didn't it? Pi2 v1.1 and v1.2
The shift from the Pi2Bv1.1 to Pi2Bv1.2 was probably the biggest change never to be announced. Word got out when people noticed the different SoC on the board (BCM2836 to BCM2837).
I've not seen the 3B with the newer SoC other than in pictures, I think that moved to 1.3, again a large change using the B0 SoC.
But that is quite a change, a resistor is not.
Has the Pi3B shifted to using the B0 stepping? The only practical reason to do that that I can think of would be to reduce inventory (one less part to stock), but that wouldn't happen unless the Pi2Bv1.2 also shifted to the B0 stepping...which--I think--would be noticed pretty quickly.
Adding another resistor may require track changes. Minor as that is, it would mean a new revision number. Whether the number makes it onto the board were we can set it is anybody's guess.
The only ones have been the original B and then once the B+ was established it would have been the Zero as it gained a camera connector.
The original Model B went through several revisions, with varying amounts of announcement being made. I have versions...with 70mA polyfuses for the USB ports, with zero ohm resistors in place of the polyfuses, and with nothing there at all (that's the Model B v2.0).
The addition of the camera connector to the Pi0 was announced.
