Prior Release Downloads

Is there a way to download prior releases?

Since MixBus 3 is compatible with Ardour 4 I would like to download that to use for tracking on slower machines if needed.

I found the news releases through the search function but they all redirect to the same download page which only offers the current version or source code.

Old binaries are no longer supported and not available for download.
If you can wait 2 days… Mixbus 4 (based on Ardour 5) is due:

If you download source code from git, then all prior versions are available via a command like: git checkout 5.3
