Improve changelog (publication) process

[mdxs]

While waiting for the next release, I checked the version history (aka changelog) on the Apple App Store entry for Pythonista 3 and it correctly lists changes for the current v3.4

However, the "Release Notes" link provided on https://omz-software.com/pythonista/ stops at v3.3 when detailing "What’s New in Pythonista".

So there seems to be a mismatch and with the upcoming release it makes sense to ensure this is fixed before it goes public.

Yeah, that's part of the documentation, and I haven't updated that at all in the first beta (also needs changes for Python 3.13). I'm working on it, should be fixed in one of the next builds.
