Older Alpha and Beta Versions

[ds5678]

Links to alpha/beta versions follow a particular format:

• https://unity3d.com/unity/beta/2021.2.0b5
• https://unity3d.com/unity/beta/2020.2.0b6
• https://unity3d.com/unity/beta/2019.1.0b5
• https://unity3d.com/unity/beta/2019.2.0b7
• https://unity3d.com/unity/alpha/2019.2.0a6
• https://unity3d.com/unity/alpha/2019.1.0a8

If a public alpha/beta exists, a link of that format should work. However, I could not find any from before Unity 2019, so this might not be entirely accurate.

Unlike 2020+, I could not find a list of beta versions for 2019.1 and 2019.2, so you'll have to manually try links to see if they work. Be aware that sometimes, a Unity version gets skipped, i.e. from 2021.1.7 to 2021.1.9.

I created new issues for all the old alpha and beta versions I could find. I don't think there are any others publicly available.
