The interactive debugger received fixes for long-standing instrumentation bugs including record literals, defrecord/deftype inline methods, destructured argument lists, and graceful degradation for oversized forms. Session quitting now uses nREPL interrupt machinery instead of deprecated Thread.stop. UX improvements include point restoration after debug sessions and a transient command menu. Tracing output moves from the REPL to a dedicated *cider-trace* buffer with folding, navigation, and source-jump capabilities. The Enlighten mode (inline local value display) exits experimental status with a test suite, bug fixes, and per-form control. A new cider-tap buffer streams tap> values and allows inspector integration. Stack frame navigation and ClojureScript rendering also received fixes. ## Full article daily.dev links to this article rather than hosting it.
