No, we have good sense. If it takes one year, probably (I mean PROBABLY because it's up to him now) @InvisionHQ may release a version to 4.1.
Advice for the next big update: DO NOT UPDATE your board before you talk to the devs, if you use 3rd-party resources. We can't hurry things just becase a couple of users did things without communicate.
------------------------------------------
4.2 version will be ready tuesday or wednesday probably and will be available to be tested by all purchases in the support board. I don't recommend use it in a live board without test, but as you already did, I don't expect you will wait for final but bear in mind that it's a decision you will take by your own and if you have any issue, a fix can take long and will be provided by the new dev.
