I have read a few threads and a wiki page, but I am still getting confused.
Until now I have used RPi Model B+ v1.2 and since it has 40 GPIOs, 4x USB and stuff, I supposed it is the RPi 2. Today I have received RPi 2 Model B v1.1 for my new project. It also has 40 GPIOs, 4x USB, but has a different CPU (or whatever that is, it says Broadcom instead of Samsung) AND it has a smaller Raspberry drawn on it. They both claim to be copyrighted in 2014.
So... which is newer (supposedly better)? Main differences?
