How deeply does API Design Patterns cover agile instability?

Explains four lifecycle states and their change policies, then illustrates their monthly progression without implementation details.

Agile instability

As explained in API Design Patterns

Agile instability is an API versioning strategy that maintains a small sliding window of versions and frequently deprecates older versions to deliver new functionality quickly.

Agile instability keeps a small sliding window of API versions, trading long-term stability for lower maintenance overhead and faster delivery of new functionality. It suits active, engaged users who can absorb frequent deprecations. section 24.3.2

A rolling version window

A typical timeline places version 1 in Preview during January, Current in February, Deprecated in March, and Deleted in May. Meanwhile, newer versions successively occupy Preview and Current, maintaining a moving development window.
