+
+### Breaking Changes
+
+- **pg**: `ExecFunc` signature changed from `func(Conn) error` to `func(context.Context, Conn) error`. All callbacks passed to `WithConn`, `WithTx`, and `WithAdvisoryLock` must be updated to accept a `context.Context` as the first parameter. The provided context carries the active transaction, enabling savepoint support in nested calls.
+
+### Added
+
+- **pg**: Nested `WithTx` calls now create savepoints instead of independent transactions. If the inner callback fails, only the savepoint is rolled back; the outer transaction remains active.
+- **pg**: `WithoutTx` function to obtain a context with the active transaction removed, useful when a nested call should start an independent transaction.
