Propose good practise

[amenk]

I would like to promote the practise to mark changes, because fellow developers might search a lot if vendor was changed when debugging errors.

Feel free to accept if you agree.

Thanks for the great work :-)

would be obosolete with #69

Ah yes I love this! Another good practice to mention to people would probably be to not to remove big blocks of code and rather comment them out with extra notification as those also will cause confusion when someone expects certain logic to be found but finds nothing (not even a comment that something was removed).

Anyhow having this in docs would be a very cool step towards the enhancement in issues already, yes :)

Will merge this over the weekend :)
