Thanks for checking. It must be something weird with my ISP and / or Akamai. After several attempts, I still only got 2.5MB. However, I was able to download the entire file from a remote server I manage.
I just installed the beta, but the installer referenced v5.0 (install dir, title of install screen, etc). Not sure if this is because I have v5.0 installed also (likely) or because the project var name wasn't updated before the release (doubtful). Anyway, just wanted to let you know.
