The old runtime xref only saw loaded namespaces, reported callers not occurrences, and didn't support ClojureScript. The new source-based xref-find-references uses a three-stage search: REPL resolves the fully qualified name, ripgrep narrows candidate files, then a namespace-aware regexp filters results per file's ns form. A configurable cider-xref-references-mode lets users choose source, runtime, or both modes. Beyond find-usages, CIDER 2.0 adds a who-\* family of commands (who-calls, who-implements, who-macroexpands, etc.) inspired by SLIME. The author notes clojure-lsp remains valuable for project-wide renames and unused-var linting, but CIDER now handles the most common use case out of the box.
