3.0.0 completed the modernisation programme (tooling, type hints, tests, documentation and standards conformance) and 3.1.0 added PROV-JSONLD. What's new in 3 summarises the 3.x line for projects still on 2.x, and the announcement post PROV Python 3.x: a major release covers what changed and who uses the package. ROADMAP.md lists the planned releases and the support policy. Feedback is welcome on the issue tracker.
