Timing on new revision of AudioMoth?

Hi all, I run a little citizen science frog monitoring project in the south-west of Western Australia. I'm super excited because I've just managed to secure enough community funding for 10 AudioMoth units. But I saw in the recent End of Summer Update that there is a new revision of AudioMoth ("version 1.1.0") to make it more robust. Is that a revision to the actual physical unit? If so, do you have any approximate timing as to when that will be in production? (I probably only have one shot at buying these units so don't want to buy the current model if an improved one is not too far away.)

Any insights would be most appreciated. Thank you.
