It sounds like you bought Halide 1. At the time, we had supported Halide 1 for three years of huge feature updates when we launched Halide Mark II. Rather than just drop Halide 1, we gave everyone Mark II and a year of additional updates.
The alternative would have been to just release a separate app called Halide 2 and stop updating Halide 1. In that case, version 1 would probably fall apart pretty quickly due to OS and camera changes year to year.
I’m genuinely curious if you’d have preferred we stopped updating Halide 1, because we’re always trying to find the best way to support users while keeping the light on.
