PPPYAbsent optional node dependencies are now accepted when the slot allows an empty bound set, with clearer guides.
Released on August 11, 2026
Dependencies
- A node dependency may now be absent when its slot admits an empty set of bounds, so optional dependencies no longer need to be present to satisfy resolution.
Documentation
- The guides now document how to add an optional dependency and correct the wording used to describe the dependency walk.
- The guides now name the both-sources failure and describe the add-path cache fallback.
- The guides now accurately describe worklist deduplication and launch vacancy.
