Hi,
Just a quick note to let everyone know that if you are having issues publishing any customisations for the 2023.115.301.7250 release, you may need to unblock file PX.Web.Customization.dll (at a minumium) otherwise you may get a validation error during publishing:

I ran the following powershell command (as an administrator) in my C:\MYOB Advanced\Customization\{Instance Name}\AdvancedValidation\AdvancedWebsite\Bin directory:
Get-ChildItem -Recurse | unblock-file

Once this was done, I was able to publish my customisation.
