[2.0 v10] Caution Triangle with ! by board info

I just started using Arduino again. I'm playing with a 3.3v Pro mini connected through a genuine FTDI board.

I'm getting a yellow triangle (see below) and can't figure what its trying to tell me.
BTW I can download the "blink without delay" which is working.

Also is it possible to widen the same box so I can see the full message.

Thanks
John

It ís a warning sign telling that something might be wrong, being off...

Thanks, I'll keep an eye on it.

To the right here is a white triangle pointing down. I guess there is message telling what it is about. Click it!
