Below are the versioning schemes used for publishing debs:
| Build target | Version format |
|---|---|
| Daily PPA | XX.YY-<revno>~g<commitish>~ubuntu22.04.1 |
| Staging PPA | XX.YY~22.04~rc1 |
| Stable PPA | XX.YY~22.04~stableppa1 |
| Archive release | XX.YY~22.04 |
| Archive bugfix release | XX.YY.Z~22.04 |
Regardless of source, the latest available "upstream version" (e.g. 27.4) will
always be installed, because the upstream version comes first followed by a
tilde (~) in all version formats.
This table demonstrates upgrade paths between sources for one particular upstream version.
