Simon specifically highlights that <code>ALTER TABLE</code> can now directly add and remove <code>NOT NULL</code> and <code>CHECK</code> constraints, a workflow he previously had to manage using his own <code>sqlite-utils transform()</code> method. The update also introduces <code>json_array_insert()</code> (alongside its jsonb equivalent) and brings significant upgrades to the CLI mode&rsquo;s result formatting via a new Query Results Formatter library. True to form, Simon leveraged AI assistance—specifically Claude Code on his phone—to compile this new C library into WebAssembly to build a custom playground interface.</p>
