PROP_DESIGN Beta utilizes a new type of propeller theory, that I created in January of 2020. Wake visualization has been added to ANALYSIS. This includes wake contraction/expansion.
I would love to get feedback on how it's working for you. If you think you have found a bug, let me know that too. Use the contact form on the 'Support' page, to get a hold of me.
Unless someone reports a bug, I don't have any plans of working on this project anymore. I started it in 2008 and it took way more time and work than I ever could have imagined. The code seems very good now, as far as I can tell. Likewise, if I get feedback from users saying the code matched test data, I will move the code out of beta status and delete the contact form.

There is no changelog. I started developing PROP_DESIGN in 2008. I tried making a changelog several different times. However, it quickly became so long that there didn't seem to be value in it. Who is going to read through pages and pages of cryptic change notes? The important thing is to use the current version of PROP_DESIGN. In any event, some of the most recent changes are listed below:

PROP_DESIGN is used in combination with several other software programs:
All source codes were compiled with gfortran via tdm-gcc. The compilation options I used are in the 'c.bat' files. You can tune these for your specific processor and possibly gain a little more speed. This shouldn't be necessary, however, as the codes should run very fast as is (using the default settings).
All versions of PROP_DESIGN are designed to run on AMD and Intel x86-64 processors. For other processor types, you will have to re-compile the Fortran 77 source code files.
If you want to run PROP_DESIGN on an operating system other than 64-bit Windows, you will have to re-compile the Fortran 77 source code files.
The best option is to use a small product that utilizes 64-bit Windows. There are many such devices available. This approach would not require any changes to PROP_DESIGN. This would allow you to design a propeller, for a prospective customer, without having to return to your office. So if you were in a meeting or at a trade show, with a few inputs from the prospective customer, you could generate a design right there.
I have never used Apple products, due to their business practices. If you want to run PROP_DESIGN on an Apple product, you will have to figure that out on your own.
