[yocto] How to keep image version and changelog

[Daniel.]

Hi everybody,

I need to versionate and keep a changelog of my images. Today I have a
file (/etc/image-version) that holds the image vesion taken from PV of
my image recipe and compilation date. I need to keep a changelog so I
can easily keep track of changes in image.

My first idea was creating an CHANGELOG variable inside the image's
recipe, update it there and have a kind of auto PV to increment at
everychange on recipe. So I can simply fix bugs and
