Given that the old forums are almost certainly going to be end up being shuttered, not even being left to be an archive and I doubt the devs will have the past patchnotes saved somewhere I’ve done a thing:
There are links to the specific updates by version number (All the way to the start of the open beta. Small updates can be searched for manually.). It isn’t perfect and not everything was pulled from the patchnotes but the important parts have been saved.
