1. Definition
<non-native Package version> ::= <Upstream version> "-" <Debian revision>;
<native Package version> ::= <Upstream version>;
<Debian revision> ::= "reading Package version from right to left, anything until and not including the first dash (-)";
<Upstream version> ::= "reading Package version from left to right, anything until and not including the last dash (-)";
- 1.2.3: Upstream version 1.2.3
- 1.2.3-4: Upstream version 1.2.3, Debian revision 4
- 1.2.3-4+deb12u1: Upstream version 1.2.3, Debian revision 4+deb12u1

- 2024-10-01-1: Upstream version 2024-10-01, debian revision 1
2. Tracking
Version tracking by comparing source and all their binary packages,after removing vendor suffix
- Upstream versions are equal and Debian revisions are equal → green
- Upstream versions are equal and Debian revision is lower → orange
- Upstream version is lower → red
- Upstream versions are equal and Debian revision is higher → purple
- Upstream version is higher → purple
- Package is in derivative, but not in Debian → blue
