What Is Known About Print Shop for Mac 4.1 by Mackiev Software?

MacOS Catalina came out in October, 2019, and Print Shop for Mac 4.0 was incompatible with it because it was a 32-bit application (and Catalina forward didn't support 32-bit applications). So I've been stuck on Mojave for over two years in order to run my existing copy of Print Shop for Mac.

During that time, Mackiev (the developer) never created a 64-bit version; it appeared that further development of the app had been abandoned.

Recently, I received an email from Mackiev stating that they were in the final stages of creating a "true 64-bit update, 4.1, of the Print Shop product" which would be "fully compatible with Catalina through Monterey". From the sound of things, they haven't actually made this available, yet, however, but expect to in the near future.

Does anyone know anything about this? Is this for real? Is it a true 64-bit app that will run properly on Catalina forward? Perhaps most importantly, will it be backward-compatible with Print Shop projects created using previous version(s) of the product?

I'm somewhat dubious of this, given Mackiev's track record with failing to produce a 64-bit app following the introduction of Catalina (over two years ago). Also, I've heard (anecdotally) that this will be a port of their Windows product, and it will therefore not have the look and feel of the original Mac version.

I very much appreciate any insight anyone can offer.
