5.0.0 is a major stable release and is the last release to support Python 2 & 3.4. 5.0.0 is mostly backwards-
compatible with 4.2.2 and is intended for long-term, bug fix only support.
5.0.0 comes two weeks after the 5.0.0RC1 and includes a small number of additional bug fixes. Note that
rdflib-jsonld has released a version 0.5.0 to be compatible with rdflib 5.0.0.
There is a large list of changes since the 4.2.2 release, see the CHANGELOG for details.
See https://rdflib.dev for the proposed future release schedule.
