Since getting my Espruino board the STM32F3 discovery board has been gathering dust! I pulled it out and am trying to update to the latest software. I don't seem to be able to find boot1 and boot0 on the board. Does the STM32F3 have a different procedure to enter boot loader then other boards?

Nope! Just the same - but because it's got a separate programmer on the board as well it's better to use that. Just follow the instructions here: http://www.espruino.com/Other+Boards

Hi! Downloaded 1v69 to F3discovery. can't download program from right pane at all, can't implement reset() and save(). they don't finish. tryed on 2 boards which were ok on previous versions...

@Andrey:
Did you see this note (from here: http://www.espruino.com/Other+Boards):

"Note: This board is more difficult to connect to. You need to power
up the board without 'USB USER' plugged in, and then plug in USB
later. If you subsequently reset the board, you'll need to unplug USB
and plug it back in."

You need to use the "other" USB connector (USB_USER) and not the one you used to upload the Espruino software.
Maybe that is the issue you are running into?
But reading your note again, you probably already tried that.
