Mike's Notes
Pipi self-versioning has resumed after being frozen since 2020. Previously, Pipi was versioned whenever developers logged changes.

Notes
Minor releases account for emergent behaviour changes in the system as a whole; the date is arbitrary. Major Releases account for phase-level changes when they occur.
It will take a while to get everything running according to plan. It requires enabling extensive automation across multiple systems. As a result, some parts will initially be out of sync.
If the Version Engine (ver) had been running since 2000, the number of changes would make the current Pipi version look something like
- Pipi 9.18.78+25,000-beta
