- The `syntax-parse` form supports unwinding side-effects when it backtracks, both explicitly with `~undo` patterns and implicitly with the built-in managed state (using `syntax-parse-state-ref`, etc). - The `db` library supports SCRAM-SHA-256 authentication for backends running PostgreSQL 10 or later. Client support for SCRAM and other SASL mechanisms is provided by the new `sasl` library. - The `lazy-require-syntax` form supports lazy loading of macro transformers. Note that the macros must obey certain implementation constraints (see the `lazy-require-syntax` documentation).
