Code Breaks Every Time MT5 releases an update!!

Hello we have developed an EA for MT5 but we've noticed every time there is an update on MT5 our code breaks. 

This is really inconvenient because MT5 releases updates constantly and each time it affects random functions (it seems like). 

So then we are left to only trial and error to figure what functions were broken this time and hope we fixed them all until the next update. 

I'm wondering if anyone out there can also relate to this and if anyone has a solution. 

Thank you.
