Question about version 1 and version 2

Hello all. I have discovered InvoicePlane :). It’s a great software. Is it safe to use 1.5.11, or set up when a version 2 comes at some point (e.g. because of data transfer and PHP updates)? Or will version 2 be released at some point?

It is safe to use 1.5.11 and there will be a version 2, but it’s going to take a while
