v1.4.1

clickhouse-connect 1.4.1

This is a patch release with two bug fixes. One restores correct Alembic autogenerate output for non-ClickHouse dialects after the ClickHouse integration is imported. The other completes the return-type annotations on the async client so callers running mypy in strict mode no longer get errors.

What's Changed

Bug Fixes

• SQLAlchemy: importing the ClickHouse Alembic integration no longer changes Alembic autogenerate output for other database dialects. The ClickHouse renderers for CreateTableOp, AddColumnOp, and DropTableOp were registered as process-wide replacements with no dialect guard, because Alembic renderers have no per-dialect dispatch. Any non-ClickHouse autogenerate run in the same process then used the ClickHouse renderers, which dropped the nullable argument from columns whose nullability was not set explicitly and injected cc_sqlalchemy imports. The renderers now fall back to Alembic's built-in rendering for non-ClickHouse dialects. Closes #832.
• Several public AsyncClient methods now carry the return-type annotations their sync Client counterparts already had. close, close_connections, query_np, query_df, query_arrow, set_client_setting, and set_access_token were missing them, so downstream projects running mypy with --disallow-untyped-calls got no-untyped-call errors on calls like await client.close() once the package began shipping py.typed in 1.4.0. The async client surface is now fully annotated. This is a type-only change with no runtime effect. Closes #831.
