Rafale prototypes status & testing

Hi all,
I have some questions regarding the 4 Rafale prototypes (C01, M01, M02 and B01).
I know that C01 and M01 were retired some years ago. But what about B01 and M02? I haven’t seen these prototypes for quite some time. The last thing I read was about the M02 conducting tests back in 2005. I suppose these prototypes are retired now as well.

My question is when exactly were the aircraft withdrawn and how much sorties/flight hours have they completed?

My other question is were these aircraft used for additional trials beyond the F1, 2 development? I mean to remember that the C01 was supposed to be used for trials with the M88-3. I know that this engine haven’t been flown aboard any Rafale.

BTW way how is the DRAAM going on and what about the M88-2ECO have these been flown on the Rafale by now?
