+## libvcs 0.45.0 (2026-06-28)
+
+libvcs 0.45.0 makes test behavior independent of execution order by removing shared state from the URL registry and the pytest fixtures. {class}`~libvcs.url.registry.VCSRegistry` now keeps its parsers per instance, so building a custom registry no longer mutates the module-level `registry`, and the `git_repo`, `hg_repo`, and `svn_repo` fixtures hand every test its own clone instead of a shared checkout — fixing cross-test state leakage for downstream test suites such as vcspull. Contributors also gain an opt-in parallel test mode via pytest-xdist.

 #### `VCSRegistry` no longer shares parser state across instances (#539)
