+
+### Added
+- `client.dataframe.sql()`: execute a SQL SELECT and get results directly as a pandas DataFrame (#141)
+- Schema discovery: `client.query.list_columns()`, `client.query.list_relationships()`, and `client.query.list_table_relationships()` to inspect table columns and relationships from metadata (#141)
+- SQL query helpers: `client.query.sql_columns()`, `client.query.sql_select()`, `client.query.sql_joins()`, and `client.query.sql_join()` to auto-build SQL statements from metadata without knowing column or join syntax manually (#141)
+- OData query helpers: `client.query.odata_select()`, `client.query.odata_expands()`, `client.query.odata_expand()`, and `client.query.odata_bind()` to auto-discover navigation property names and build `@odata.bind` values from metadata (#141)
+- `SELECT *` raises a `ValidationError` with a clear message instead of sending the query to the server, which does not support wildcard selects; use `client.query.sql_columns()` to discover available columns (#141)
+- SQL safety guardrails: write statements (`INSERT`, `UPDATE`, `DELETE`, etc.) raise `ValidationError` before hitting the server; cartesian joins (`FROM a, b`) and leading-wildcard `LIKE` patterns emit `UserWarning` (#141)
+- `client.tables.create()` now accepts an optional `display_name` parameter to set a human-readable label for the table in Dataverse; defaults to the schema name when omitted (#164)
+- Opt-in HTTP diagnostics logging: pass a `LogConfig` to `DataverseConfig` to log all HTTP request and response traffic to rotating local log files with automatic redaction of sensitive headers (`Authorization`, etc.) (#135)
+
+### Changed
+- `client.tables.create_lookup_field()` now automatically lowercases `referencing_table` and `referenced_table` to valid Dataverse logical names; callers no longer need to call `.lower()` manually (#141)
