@brianteeman I thought you could update alphas via the update manager?
Either way, there shouldn't be a PHP error being thrown.
Functionally you can use the install BUT we never do the update scripts to handle changed files or changed database stuff so it is unlikely to work.

One does not update an existing install at this time.
So, if one has been working on some things and has to do a fresh install that would mean the altered files would have to be copied over to the new installation.
There is nothing new about this. This has been the practice for 13 years
@dgt41 Is this the right place to start: https://github.com/joomla/joomla-cms/tree/4.0-dev

So let's keep going that way, right? Sounds like an arguments for a change to me.
mbabker:
For what it is worth, there is zero technical reason why upgrades between anything but stable releases cannot be supported.
Are you volunteering to do the required work?
So it can be done.
As with every joomla pre-release there is no upgrade path between pre-releases
