Looks like it. Unfortunately I can't support and release VST2 versions of any of my plugins, as VST2 has been deprecated and it's not possible to get a new license agreement with Steinberg for VST2 plugins. :(
I think you'll have to look for either a way to load VST3 plugins into a VST2 host, or switch to a different DAW altogether, but that might be a difficult step to take.
