Preparing for the new update

Hi. Im using Blackfyre since the launch week. And i saw in some topic the next update will be tommorow or this week. Im a french user and of course the website is made in english. My community is in french also. So i add to translate with PO or by changing the code. (Also did some changes in the code because of some feature lacking for me.) Since the new update is coming soon how will i need to install this update and what can i expect to change/install to make it work? Also. Where can i find the updates? I never saw somewhere where i can see that my theme is having an update possible to download either in wordpress or envato. Thanks for the answer!
