QUANTCONNECT COMMUNITY
I was looking through the discussions and realized there are updates to LEAN somewhat often, and could result in needing to change your code. Could this effect live projects too? Several of the update posts say a certain line of code would no longer work or some things would have to be re-written. It would be very conscerning if an update came out that could make a live project no longer functional, so I figured I must be missing something.
Thanks!

Live project (i.e. already running) is not impacted by changes in Lean version in my understanding, it's an already compiled assembly that will not change during the server's uptime. A different version can happen to master before your next launch however. (at which time assembly is recompiled to link with newest Lean assembly version) Beware that highly unusual circumstances may make a live project relaunch necessary, if your code is out of date you might be unable to immediately relaunch. Before major (intentionally breaking interface) changes they branch off the current master - in which case you can pick an older branch for your project.

Ok that makes sense, thanks for the help.
