+# TeaQL Python 0.3.0
+
+Tracking: [release issue 45](https://github.com/teaql/teaql-python/issues/45).
+
+This release publishes the merged request intent and Trace Chain implementation,
+including query and mutation lineage, independent graph ownership, relation
+aggregates, facet tracing and safe SQL diagnostics. Generated examples cover
+shared references, loaded snapshots, Checker overlap and repeat bootstrap.
+
+Regenerate applications when upgrading from 0.2.x: request and lineage
+contracts have changed. Logging remains enabled by default, with sensitive
+parameters masked and the existing disable controls preserved.
+
+Release gates cover native tests, every retained example, an isolated generated
+consumer of the immutable internal 0.3.0 wheel, and public PyPI delivery.
+External-provider skips are recorded separately; they are not passing tests.
