Worth doing. There was another update just last week.
Here's Polar's updates info page

I'd be interested to hear how you go on. I got a Vantage M a couple of weeks ago to replace an expired 910xt, but due to illness haven't been able to try it swimming yet.
One other thing. I found after my 1st update the 'fixes' the firmware didn't all work until i did an off and a back on again. (Not swim specific, but even the fixes to sync properly with the Galaxy phone I was using. )
